Zero-modem connection. From your experience
Zero-modem connection. From your experience.
Why can still be needed such a connection? For example, a friend came to you and wants to fill you a couple of times from a rocket installation. Or you have two computers at home (and this is not such a rarity) and you want to have access to the Internet from both computers, while having one modem. Or maybe you need to transfer multiple large files from one computer to another.
For such a connection, it is enough to buy a so-called zero-modem cable. Cables for COM and LPT ports are approximately the same ($ 3 - $ 6), the data transfer rate is also approximately the same. The advantage of such a compound is low cost and lack of additional equipment. Disadvantages: a short distance (up to 5 m) between computers; Low data transfer rate; One-sided data exchange management.
Who remembers the Doom1 at work or at the institute, he probably remembers the so-called "lace" - 3 wiring attached to some of the COM ports of two tres (Intel 80386). This simple adaptation allowed to play against a friend or together against monsters, which made a new element of acute sensations to the game. With the advent of Windows and games that require communication using IPX protocols, TCP / IP about this device forgot. And in vain. Everything is not so difficult, and for home it is a very attractive solution, and the name is NULL-MODEM. So, zero-modems are two types: for COM (serial) ports and for LPT (parallel) ports. The first type is connected to the same port type as the usual modem (their usually 2), the second to the printer port (which is not entirely convenient if there is a printer).
Zero-modem connection for Som ports is convenient because the computer, usually, one COM port is free. The disadvantage is that the data transfer rate is only 115200 bits / s. Just 2-3 times faster than good connection with the Internet. With this speed, 1 megabytes of data is transmitted a little more than a minute. Actually, if you decide to use a zero-modem cable for Som ports, it is better to buy it. The fact is that there are 2 types of Som ports: DB-25 (wide, 25 pins) and DB-9 (narrow, 9 pins). On the radio bearer or in the firm trading in components for computers, you can purchase a universal zero-modem cable. At each end of its end, the pair of connectors is one for DB-25 and one for DB-9. If you decide to solder it yourself, then use the scheme below:

|
I do not recommend trying to insert a cable into connectors when the power is turned on at least one of the computers: you can burn the port. Well, if you still do it, it is first necessary to touch the connector with the housing. If you do not turn off the computer connect, you will still have to reboot to initialize ports.
What I still noticed: there was English Norton on a laptop, and I had a Russian, communication programs were respectively called telnet.exe and telemax.exe. When transferring 2 MB of information, about 300 errors were gained. When I installed on two machines the same Russian version, then the number of hibuses decreased to zero. Let you not frighten the inscription in the upper right corner of Offline - it is necessary. With Norton you can work both from DOS and under Windows. I checked only under Windows 98. True, the communication program window must be actively, otherwise the speed drops greatly and the number of errors increases, but the connection is not interrupted.
No matter what connectors to use: 9 and 25, 9 and 9 or 25 and 25 Contacts, the main thing is to specify in the TELEMAX program from the Norton program set, which you need to use such a port. If the computer has been turned on, then you need to reboot after the connection. I could not find a long time on the Internet Norton Commander - there were only non-working links. Therefore, I will lay out for downloading the Norton shell with Telemax program, we need it. The appearance of her shell I led above. For the convenience of downloading and transferring the diskette, I pretty cleaned the folder, leaving, actually Norton Commander and Telemax. The default settings can not be changed, but you must check the port where the wire is connected. I can say more - if there is no connection and not curved hands - the port is incorrectly specified. After changing the port, you need to save the settings so that they are with the next program download. To check, you run on two TELEMAX machines and send the zmodem file with one. The download window automatically opens. At the end of the download, a beep sounds.

GreenConnect RUSSIA - manufacturer of the linker, modem and NULL modem cable COM port DB 9 RS -232.
In St. Petersburg, since 2016, the production of cast mom Mom Mom Cable and cable cOMMA-Dad Complete For the modem made it possible to largely expand the range and model range of products.
Using modem or zero-modem Device Management CablesCisco. or game consoles, terminals, cash terminals, various control devices, modems require both standard and special layout.
GreenConnect manufactures zero modem and modem Cable COM port RS-232 both with standard wiring and special, individual schemes. For standard layout scheme zero modem The cable is used nine conduction cable. IN modem cable GCR-DB9CM2M is also involved all 9 prferrers.
High quality, shielded, stranded, soft, copper conductor allows you to use modem Cable GCR. both at home and for industrial purposes. Factory production modem cable It guarantees its performance for a long time, thanks to internal fixation using Injaction Molding technology.
Modem Cable COM port GCR-DB9CM2M models are made long from 50 cm to 10 meters, just like extension PAP Mom Com Ports of the GCR-DB9CM2F model.
Partnership directly with the Russian manufacturer GreenConnectRussia. allow you to save significant funds and use high quality modem cable For their tasks.
You can order or buy from the warehouse zero-modem cable In any quantity at the best value.
Please note that the molding of the RS232 modem cable is diverse (depending on the technical tasks).
Playing scheme semiduplexrS-232 cable
This scheme is used to control 2 devices that send data in the floorduplex. For example, one device sends data and both other devices are waiting for incoming data.In half the duplex mode, both devices cannot transmit simultaneously. If this happened, then the data would be impossible to consider. This method is used in all connection schemes.from the main device to the receiving. In this method, the computer (P3) cannot send data and intervene in the exchange of data between external devices.
Playing scheme duplexrS-232 cable
This cable is used when you must control the exchange of data between two external devices that may pass async data (full duplex mode). You need 2 RS232 port on your computer (separate port for communicable and incoming data). Modern monitor serial port can show both sides of the full dual communication RS232 in the "double ports" method. In this method, the computer (P3, P4) cannot send data and intervene in the exchange of data between external devices.
Zero modem cable is very necessary thing in satellite farm. First of all, for firmware of satellite receivers. But not always it can be bought here and have to do it yourself.
As I already said 0 modem cable We are useful primarily for the firmware of satellite receivers. And if for this you can use a short, which is easier to buy, then for the cardchairring through the computer almost always needed a long or very long (made up to 15 m.). And it is better to escape yourself. And it is done quite easily.
How to make himself zero modem cable (RS232) cord for tuner firmware do it yourself?
We will need two DB-9F connectors, soldering iron, solder, cable - twisted pair, as it is suitable for me just right (you can and the other, there is a telephone right at hand), schemes and skillful hands.
There are several connection options, but most often you need a cable for three contacts. Well, if this is not suitable - then we make full of all contacts according to the figures below.
Not a complete zero modem cable is almost always suitable. But he has a variety when his contacts go
Contacts 2 - 2 and 3 - 3, 5 -5 straight
Contacts 2 - 3 and 3 - 2, 5 - 5 not direct
It is the last not straight line coming most often.
Spacking the RS-232 port in satellite receiver can be like "dad" and "moms".
"Mothers" are much more often found so I advise you to do with two "mammies" at the ends.
It is indirect zero-modem cable With two moms, and with the calculation of the right-left, suitable for the firmware of most satellite receivers, or for a sharing.
Problems with "firmware" receivers. No COM port. Using a laptop
In the majority of "old" computers and laptops purchased more than 5 years ago, there have always been several COM ports (RS-232). At the very least, there was always at least one "RS-232" connector.
Fig. 1. Connector on computer case
Different external equipment connected to it: mice, printers, modems, specialized equipment. Therefore, there were no problems with connecting the receiver to a computer for the "firmware". It was enough to simply connect, run the program to update the receiver and calmly do everything you need.
In modern computers, the "RS-232" connector is often absent. There are problems, often very unpleasant. In most receivers there are no other ways of "firmware" except the use of "RS-232". And the "USB" input to connect an external storage flash drive is not all receivers.
And sometimes there is another problem: the laptop has a "COM" port, but with the receiver of one model it works, and with others - no. This is due to the violation by the manufacturer of the laptop of the RS-232 data transfer standard. They go to this in order to save the battery charge energy. If the receiver has been technically scrupulus and accurately, the receiver will be installed a special chip for the "COM" port. Thanks to this microcircuit, the receiver will work with a laptop, and with a computer. But the installation of the microcircuit increases the total cost of the product, and recently the manufacturers save even on these trifles! Therefore, the problem of incompatibility of laptops and most receivers arises.
When using the computer, the problem of lack of necessary ports "RS-232" is simply solved: it is necessary to purchase an additional module with "COM" ports. This board installed in the computer is called "PIC-COM" or simply "COM payroll".
Fig. 2. PCI card for a computer with two "COM" ports
If you are not strong in computers and previously never dealt with the installation of additional equipment to the computer, then contact a specialist! Otherwise you can "kill" expensive equipment.
After installing the board in the computer, the Windows operating system is "OS" assigns a number of installed number, for example, "1", "2" ... "25".
When using a laptop, the usual fee from the computer cannot be installed: not the standard and size. There are two ways to solve this problem: expensive, but high-quality, and cheap, but not fully compatible. In the first case, you must purchase a special board with ports for a laptop. The price of these fees is high, and acquire, even under the order, I could not have been this fee
Fig. 3. Place for laptop with "COM" port
And there is a catch: in "old" and "new" laptops two different standards for additional equipment! Before purchasing, check with the instructions for your laptop!
If you could not purchase a board on a computer or laptop, then one output remains: "USB". In almost all modern computer models there are "USB" exit, at least two, and even eight! There are various "USB-COM" converters.

Assembly and configuration
Here, everything is done elementary - we make a fee, drill the 4-re holes and attack all the details.
As a result, you must have such a transition:
Fee, so as not to oxidize, you can blend a polyurethane varnish or any quick-drying car varnish, which is at hand.
Next, this device is connected to the USB port of the computer.
Windows will detect a new device and asked the driver.
We go to the site of the software and pump the latest version of firewood
At the time of writing the article, the most recent driver was this.
After feeding Windows Driver, a new COM port of Prolific will appear in the system: 
Now it is necessary to check the adapter's performance
To do this, on the adapter in the COM port connector, a screwdriver or wire with a closer circuit 2 and 3 (on the connector itself, numbers are usually knocked out with contact numbers - look closely) as an option, you can attack a temporary jumper:
Next, launch the program "Hyperterminal" (Start-\u003e Programs-\u003e Standard-\u003e Communication-\u003e Hyperterminal)
There is no hypertherminal on Wist and seven! Therefore, you will have to go to Google / Yandex to roll out a hyperterminal or any of its analog.
Select our new Som port in the connection settings:
Now launch a connection, choose English layout and try to print something.
Symbols of press keys should appear on the screen:
If the letters do not appear, check the installation
That's actually all!
Now it remains to remove the jumper from the contacts 2-3 and you can use the adapter for direct purpose.
Those. In the free connector of the "USB" laptop, the input of such a "converter" is connected, the driver (control program) is installed from the drive from the kit and the system settings appears a virtual COM port with a assigned sequence number.

BM8050 health check without external equipment
To check the transfer and reception of all the necessary modem signals according to the connection of the SOM device.
Set jumpers to contacts 2-3, 4-6, 7-8 soms connector VM8050.
Connect the device with USB port PC.
See which port OS has allocated for the device, for which go to the Start --- Setup --- Control Panel --- System --- Equipment --- Device Manager - Ports (Som and LPT) --- Silicon Labs CP210X USB TO UART BRIDGE (COM1).
Run the standard HipERTERMINAL application for Windows from Starting Programs --- Standard --- Communication --- HiperTerminal.
Stop the running connection if it is active, for which you press the above call to stop.
See which port is used by the program to communicate with the device, for what to go to the left at the top of the property and opposite "connect via" select the same port as in the device manager (in our case COM1).
In the same window, make sure that the "hardware" flow control is selected in the program, for which click the button in the center "Configure" and in the lower window "Stream Management" Select "hardware".
Exit the program setting, for which click OK, once again.
Type the text "Text" in the HiPerterminal program, while the text "Text" text is printed on the screen, which confirms the serviceability of the device.
Remove the jumpers from contacts 2-3, 4-6, 7-8 soms connector VM8050.
Type the text "Text" in the HiperTerminal program, while there is no print on the screen, which confirms the serviceability of the device.
Configuring the driver and select the port for the USB-COM adapter
Here we will be waited for the first problems: first, the OS could assign a virtual port to the virtual port, for example, "25". A program for the "firmware" of the receiver allows you to work with port numbers from one to four. Secondly, not all USB -Com converters can work with the program for the firmware and the receiver itself. The reason is that manufacturers of equipment produced their products and programs to them differently. Check all the converters are necessary individually for your program and your receiver. It often happens that with one equipment the converter works, and from the other, no.
If the first problem is eliminated by changing the port number in the OS settings, then the problem of compatibility of the equipment, programs and the converter cannot be eliminated.
To change the number assigned, you must change it manually. To do this, you need to log in to the Device Manager: "Start" - "Setup" - "Control Panel" - "System".

DE-9 TO DE-9, DE-9 TO DE-25 CABLES. Use this Cable to Connect Two Devices Equipped with Serial RS-232 Interface. This Cable May Be Used to Connect Any RS-232 Equipped Device To Computer, Connect Two Computers Via Com Serial Port and So ON. RS232 Cable Colors Included.
The Purpose of a Null-Modem Serial Cable Is to Permit Two Devices to Communicate with Each Other Without Modems Or Other Communication Devices Between Them. To Achieve This, The Most Obvious Connection Is That The TXD Signal of One Device Must Be Connected to the RXD Input of the Other Device (And Vice Versa).

Some Devices Use Other for Flow Control. ONE OF THE MOST COMMON SCHEMES IS FOR THE DTE SIGNAL IF IT IS READY TO SEND DATA, AND DCE (THE MODEM) TO SEND DATA, AND DCE (THE MODEM) TO ASSERT CTS WHEN IT IS ABLE TO RECEIVE DATA. By Connecting The Cts Pin of One Device To the CTS Pin of the Other Device, We Can Simulate This Handshake.
ALSO, IT IS COMMON Convention for Many Devices to Assert The Dtr Signal When They Are Powered on, and for Many Dce Devices to Assert The DSR Signal When They Are Powered On, and to Assert The Cd Signal When the Are Connected. By Connecting The DTR Signal of One DTE to Both The CD and DSR Inputs of the Other DTE (And Vice Versa), We are Are Able to Trick Each DTE INTO THINKING THAT IS Connected to A DCE THAT IS POWERED UP AND ONLINE. As a General Rule, The Ring Indicate (RI) Signal Is Not Passed Through A NULL-Modem Connection.
