5.3.1 Introduction
Fig. 5-1: Linking ZUP units with RS232 control.
5.3.2 Rear panel connectors pinout
OUT
The RS232 interface is accessible through the rear panel IN/OUT jacks. The jacks are 8 contacts each
and conform to EIA/TIA-568A requirements. The IN and OUT jacks are used to connect the units in a
RS232 or RS458 chain to a controller. The data format is ASCII, 8 bits/character no parity bit, one stop bit.
The baud rate can be selected to one of the 6 possible rates between 300 and 9600bps (refer to
par.5.2.3).Rrefer to par.5.6 for detailed explanation.
Up to 31 ZUP units can be connected to the RS232 control as shown in Fig.5-1.
IN
Tx and Rx are used for RS232 communication. Txd +/- and Rxd +/- are used for RS485
communication. Refer to RS232 and RS485 cables description for connection details.
