Parameter
Description
RS232 / RS485
Setting:
Unit Number:
Especially with RS 485 applications it is necessary to attach a specific
address to each unit, since up to 32 units can be connected to the same
bus. You can choose any address number between 11 and 99.
Factory setting = 11
The address must not contain a “0“ because these numbers are reserved for
collective addressing.

Protocol Setting:
The serial port of the unit can operate in either “PC-Mode“ or in “Printer
Mode“.
With “PC-Mode“, the unit waits for a request string and responds with a
corresponding data string. For details of the protocol see description
“SERPRO“.
With “Printer Mode“ the unit sends data without any request and under
Timer control as described subsequently.
As soon as the unit receives a character, it automatically switches to PC
Mode and operates according to protocol. When for a period of 20 sec. no
character has been received, the unit switches automatically to “Printer
Mode“ and starts cyclic data transmission.
