DSUB–connector
A 15-pole DSUB–connector serves as the connection for the interface X.21 (Figure 16).
Standard 15-pin D-subminiature plug connectors conforming to MIL–C–24308 and DIN 41652
can be used.

The 15-strand data line should be twisted and screened. The pin assignment can be seen in
Figure 17. The byte–timing is not supported. The cable length for the maximum transmission
speed (512 kBit/s) must be ≤ 100 m (300 ft). Between the communication converter and the
X.21 interface of the communication device, it is recommended to have short connenctions,
in order to avoid electrical interferences. The communication converter should be installed
near to the communication device (DCE).
Please observe additional installation instructions!
