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 RS232 (#85603)
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.
