Our line of null modem serial cables allows two DTE or DCE devices to communicate with no conflict in data transmission. The transmit and receive signals are crossed to ensure proper data transmission.
Each null modem cable is designed with a rugged, overmolded construction that provides added strain relief and a solid connection each time. Plus the cable is foil shielded for EMI/RFI protection from surrounding office equipment and flourescent lights. Thumbscrew connectors provide a fast, easy connection every time.

Most likely you need a null modem cable. It has however been a long time since I used a serial cable with anything but a modem. It is called 'null modem' because it replaces the functionality of a modem be switching the send and receive lines.
Do I need a Null modem cable, straight through cable, a modem cable or what??? Archived from groups: comp.periphs.printers Standard serial port is the one with only nine pins. The usual printer port is the parallel port & if you look at the printer end it usually looks similar in shape to the computer end but instead of having two holes for screws, it has 'thing' each end for folding in the wire-like clips to hold the cable in. If that is the case, then just an ordinary 'parallel printer cable' will do it. BruceM 'samurai' wrote in message news:[email protected]. I've got an Epson LX-300+ that needs a serial printer cable.

You say the port is working fine - how have you determined this? Be aware that Standard COM ports - 9-pin or 25-pin - are invariably MALE on the machine.

Someone with experience please let me know which serial cable I need to connect a printer to the serial port on my controller. I would also assume it should work on COM1 from a PC. There are whole books written on the subject of how to connect serial devices via COM ports. The reason is that the 'standard' was derived before the PC was dreamt of, and computers were mainframes with (often remote) terminals. The standard defined two types of equipment: Data Terminal Equipment (DTE) - the remote terminal, and the mainframe port (unless it had a modem built in) Data Communications Equipment (DCE) - the modems used at each end of the intervening comms line.
'pooter DTE modem modem DTE terminal. Each of these types has a different pinout. In 25-pin numbering, transmitted data (TxD) is on pin 2 of a DTE. Pin 2 of a DCE is receive data (RxD). Then came the PC. It was (rightly) designated as DTE. People who wanted to connect their remote terminal (DTE) directly to the PC COM port needed a cable that correctly crossed over not only the data lines (2-3 and 3-2) but also correctly configured all the necessary handshake lines to convince both devices that the modems were there and on-line.
Manufacturers then complicated the scene by introducing serial printers configures as a DCE so that it could be connected with a 'straight' cable. And some produced machines that could be configured as DTE or DCE at the flick of a switch. SO the short answer is that there is no simple universal answer to questions like yours. You can try a number of cable types to see if you have success. Bear in mind that the standard describes the elctrical properties of the ports, and requires that any line can withstand an indefinite short to ground OR indefinite contention. (Contention is when two outputs - one HIGH and one LOW - are connected). So if the ports are compliant ( and the majority of laptops and PC's of the last decade aren't truly compliant, but IMOE meet the above safeguard) then you can safely test - with cables or a multimeter.
If both ports are 25-pin, then you can fairly simply determine the DCE/DTE sense of the port with a multimeter and a resistor, or just a multimeter, as follows. Connect the multimeter (volts scale) between pinundertest (PUT) (i.e.
2 or 3) and pin 7 (signal ground). Note the voltage, then apply a load of say 1K ohms or less between the probes. If the voltage collapses the PUT is an INPUT (RxD) but if it holds up above 3 volts it is likely an output. After testing both 2 & 3 on each machine you have at least determined their port sense and this tells you whether you need a null modem cable or not - two the same will need a null modem cable of some kind. The harder part is identifying what handshake line connections the ports require to happily Tx and Rx.
That is a bit long to describe here. I suspect that's why they produce whole books on the subject. If you do find the ports require a null modem after testing as above, google for 'null modem pinout' and the most common ways of defeating hadshake requirements should appear.

How to Connect an Epson Serial POS Printer Beagle Hardware How to connect an Epson Serial POS Printer A serial connection is probably the most common way to connect an Epson printer to the computer. A serial connection involves a pair of wires (transmit and receiver) along with the status and handshaking wires. The data cable connects the serial port on the computer to the serial adapter card on the printer. If installing a Serial Buffer II,. Required Components. Epson POS Printer with Connect-It serial adapter (UB-S01 or equivalent). Windows computer with serial port Epson Printers Covered.
and Setting the Connect-It Serial Adapter Install the Connect-It serial adapter into the Epson TM series printer The adapter can replace the existing adapter and is held in place by 2 screws. The most common problem we've had with serial adapters and printers isn't the printer at all - it's the cable! There's a wide variety of connection schemes used to connect a serial printer. The most common is the null modem type connection where the transmit and received lines are crossed. Epson also recommends crossing the DTR with the DSR and the CTS with the RTS lines. Very often the serial printer is attached using an internally wired adapter which converts the DB-25 connector to a phone type (RJ-11) connector.
The connections can be wired inside the housing for custom wiring options. Note: The DB-25 cable connector on the printer is a serial connection while the serial interface connection on the back of most computers is not a DB-25 connector but a DB-9 male.
The DB-25 connectors commonly found on the back of computers is the parallel interface. This is confusing, but it's the way it is.

Getting Initial Printer and Connect-it Adapter Settings - the Print the initial settings of the serial adapter by running the self test. Run the printer self test by holding down the feed button while turning on the printer. The printer will print a list of initial settings including baud rate, data bits, parity, stop bit, flow control (handshaking). These values will be needed when configuring the serial port in Windows.
Configuring the Computer Check the POS application to determine what the port settings should be on the computer. The POS application and the printer must have the same baud rate, data bits, parity, stop bit for the printer to print legibly. Also the handshaking must be set the same for the printer to print at all. You can change the interface settings of the printer using the on the underside of the printer. See the for the model of printer you are using for specific switch settings. Verify the port you are using by checking the port in the Device Manager under the System applet in the Windows Control Panel. To obtain the latest Device Drivers from Epson:.
Download and Install Epson’s drivers available from. Click on TECHNICAL RESOURCES. Select the printer model under the menu.
Click the download drivers on the printer page. Configuring the Printer in Windows First off, it should be said that the serial printer is not Windows plug and play compliant. You need to make a few changes in the printer settings in Windows to get it to work with the serial adapter. Specifically you need to configure the serial port you are using to connect with the printer.
Installing the Epson in Windows Unpacking the Drivers After downloading the driver installer from Epson, the drivers need to be unpacked before the installer can run. Starting the Installation The installer walks you through selecting the model and interface you are installing drivers for in Windows. Add the Serial Printer Press the 'Add' button to add the new printer to Windows. Selecting the Printer and the Printer Port Choose the Epson model of the printer installed from the pull-down menu and choose the type of interface in use (Serial) for the port type. Setting the Port Settings for the printer Insert the baud, bits, flow control and parity settings from the printer obtained in the, above.
Also select the number of the COM port on the computer connected to the printer. Installing the Driver Files The installer will summarize the drivers selected. You can back up and change the driver here, if necessary. Completing the Driver Installation The drivers will now be installed with the model and port selected.
This completes the installation of the Epson printer drivers. Open the printer in the Windows Printer Folder. Select the Ports Tab.
Turn off bidirectional support, if experiencing problems printing. You can try selecting the serial port in use (COM4 in the above example). Press the 'Configure Port' button to open the properties screen. Enter the same settings as were printed out in the adapter self-test. We recommend that you run off the 'bidirectional printing' option on the Ports screen. Installing the Printer Driver in Windows After installing the drivers, the printer should be visible in the printers folder of the Windows Control Panel. You should now be ready to test the printer by printing some text or by pressing the 'Print Test Page' button in the General Tab of the printer properties.
If the printer fails to print the test page then check:. Power cable is installed and the printer is turned on. Data cable is installed on the printer and the computer. Port settings are set the same on the printer (from the ) and in Windows. The COM port selected in Windows is correct. The data cable has the right configuration for the printer and computer in use. Using the wrong data cable is the most common problem with new installations.
The printer will fail to print unless the cable is compatible. Utilities to Run on the Computer You can verify connectivity by running the Epson Flash utility. Epson Flash Utility The Epson Flash Utility is normally installed along with the Epson printer drives. It is used to upload bitmaps to Epson printers, but has a simple communication test which can check for basic connectivity between the computer and the printer. Pressing the 'Comm. Test' button on the Setup tab of the utility will give a go/no-go indication of basic connectivity. Running the TMNet configuration utility on the Computer The TMNet network utility is not compatible with the serial interface.
Connectivity Problems, never printed. The data cable is incorrect.
Typically serial printers need to use a. This cable is not straight through - it crosses transmit and receive lines. The has not been installed for the serial adapter and printer in use. Check the serial printer cable is plugged into a serial (COM) port on the computer side.
On the computer side this is typically a. The printer or the interface card is defective. Confirm printer operation.
Confirm interface card by swapping with another interface card or printer. Prints Garbage.
You didn't copy the DIP switch serial settings from the old printer to the new printer. The interface settings are not the same on both the printer and computer. Run the to show the current settings on the printer.
Check the computer side to see that settings are the same. Settings can be changed on the printer using the.
The printer selected in the software is not correct or the software doesn't support the printer in use. No longer prints. The TM printer is turned off. Turn on the TM printer. Confirm the connection of the power supply unit or the voltage of the commercial power. The TM printer is offline.
Turn the TM printer online. The ERROR LED of the TM printer is on or flashing. Remove the error cause. The printing port of the driver on the computer side is not specified correctly. Confirm the driver setting on the computer side. The printer is not online in Windows.
Check the status of the printer in the Windows Control Panel, the printer should show status as ready. Tip: try stopping and restarting the Print Spooler from the Services applet of the Control Panel. Printing is slow.
There are problems with the computer. Printing speed may go down due to problems with the network system or applications.
