3.5.1 Switch nos. 1-5 - Unit Address

A unique address can be assigned to each DP503 in a multi-unit installation for

remote control applications using the RS-232 connector J108 Rem/Download.

Individual units can be uniquely controlled using this feature.

Note While individual units can be controlled this way, status information from a particular unit cannot be
retrieved remotely using the serial port. Instead, individual status information can be retrieved using the
separate connector J109 Status.

The address is set using conventional binary codes as follows:

S101- S101-
