7.1 Serial Interface
7.1.1
Serial interface RS232 (V.24) at connector J2
Connector at printer: JST -SH (5pin). >>> Cable: GKA-406: The other end has a 9 pin SUB-D socket. The as-
signment is 1:1, matching the serial interface of the PC.
Please note that the DSR and the DCD ar e terminated on some interfaces.

RS232
The interface cable that comes with the set connects
plug-in connector with the RS232 connection (COM in-
terface of a PC) on the other end. An open-ended cable
with 5 single wir es is available as an option.
TTL
For OEM, a special version with 3.3V TTL levels is
available.
GeBE COM
In this setting, the printer uses the GeBE - Ir pr otocol
for communicating. The pr otocol can be used thr ough
the RS232 as well as the TTL.
Thr ough the CRC pr otected transmission blocks, a se-
cur e data connection can be r ealized.
