Serial Cables

To cable an unrecognized device:
1. Make sure the device is a serial device.
Peripheral devices are cabled to the serial ports on your patch panel.
This applies only to serial devices.
2. Determine whether the device is DCE or DTE.
The manual or your dealer should have this information. Modems are
generally DCE devices; most terminals and printers are DTE devices.
3. If the device is DCE, use a modem cable.
Begin by trying the cables with the pin configuration specified earlier in this
appendix. These cables work with most devices.
4. If the device is DTE, use a null modem cable.
Begin by trying the cables with the pin configuration specified earlier in this
appendix. These cables work with most devices.
If these typical cable specifications do not work, see the manual for your
peripheral device to determine which pins are active. Also see “Patch Panel
Pinouts” in Chapter 3 to determine which pins are active for the serial ports on
your patch panel.
You must wire the cable connectors according to the needs of both the
peripheral device and the serial port on your patch panel. You might have to
experiment to find a successful compromise.
