The RS232 interface is accessible through the rear panel IN/OUT jacks. The jacks are8contacts each
and conform to EIA/TIA-568A requirements. The IN and OUT jacks are used to connect the unitsina
RS232 or RS458 chain toacontroller. The data format is ASCII,8bits/character no parity bit, one stop bit.
The baud rate can be selected to one of the6possible 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.
