Connector Assignment

The combined interface is equipped with a 25 pin

DB25S connector.

Connector Transmiss. Printer

18 Transmission Loop TTY –T-Loop +T-Loop

21 Transmission Loop TTY +T-Loop –T-Loop

25 RDY (READY/BUSY) RS232C

The polarity of the receive and send loop alters when

the supply side changes (active/passive) ,,Printer Passi-

ve“ signifies that S1 and S2 must be in position 1.

When using the serial interface RS232C, the interface

cable must be checked for proper contact connections.

In the case of software printer control (e.g. XON/XOFF)

the pin assignment is identical for both the standard and

combined interface. The hardware printer control requi-

res different connections.

The pin assignment of the TTY part of the combined in-

terface corresponds to the pin assignment of the old

TTY interface.
