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 RS485 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). Refer 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.
