RS-232 Cables

Connect the HomeBase device to the host workstation or other device by plugging an RS-232 serial cable into the RS-232 Port (see page 9-3)on the back panel. The wiring of your cable depends on whether the other device is set up as a Data Communication Equipment (DCE) or Data Terminal Equipment (DTE) device.

The HomeBase device is configured as a DCE device. To communicate with another DCE device, use either a null modem adapter in line with a standard RS-232 cable, or a null-modem serial cable. To communicate with a DTE device such as a computer, use a standard (or straight-through) RS-232 cable.

You can make your own cables by following the pin configuration in the chart below. To do so, you must determine if your host RS-232 device is 9-pin or 25-pin, and whether it is configured as a DCE or DTE device.
