Setting up the HomeBase for RS-232 Communications
Connecting the Cables
Connect the HomeBase to the host computer or other device by plugging an RS-232 serial cable into the RS-232
Communications Port on the rear of the HomeBase. The wiring of your cable depends on whether the other device is set up as
a Data Communications Equipment (DCE) or Data Terminal Equipment (DTE) device.
The HomeBase Communication Port is configured as a DCE device. To communicate with a 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.
