Mechanical features and enclosure

The T-switch comes with three 9-pin RS232 ports and is
integrated into a 45mm wide plastic housing for mounting on
standard rails conformal with DIN EN 50022-35.

Configuring the serial ports and T-switch 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 T-switch and use the
attached plug to assist in pulling off the housing cover.

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.
The pinout for the individual ports can be found in the follo-
wing tables.
