Interface Cable for RS-422 / RS-485
To control the Hermes by RS-422/ RS-485 interface, only the signals TDATA+,
TDATA-, RDATA+, and RDATA- are necessary.
Check the pin assignment for the interface of your computer, and use the pin
assignment of the printer as shown in table B-1 to obtain a suitable cable. The
connectors of TDATA+ and RDATA+ as well as TDATA- and RDATA- at the
plug-in-connection of the cable must be united. If there is a very large transfer
distance a termination of the cables is recommended.
