Configuring the serial ports and device operating
modes requires opening the housing of the device. For this
purpose it is advantageous to screw a SUB-D plug with body
to one port on the Multi Computer Adapter and use the
attached plug to assist in pulling off the housing cover.

Wiring assignments

The RS232 ports A and B are implemented as SUB-D female
connectors with DCE pin functions, and port C as a SUB-D male
connector with DTE pin functions. This design ensures that the
device can be wired into the majority of applications with stan-
dard 1:1 cables. In addition, this pin configuration make instal-
lation and startup easier, since the data transfer can be tested
first without involving the T-switch by simply connecting the
cables together.
