Pin-Assignment Of RJ-45 Socket And Extension Cord:

Connecting DPC 4000 paging stations to the DPC 4000 IN connector is performed using common RJ-45 extension cords, where the conductors are twisted in pairs as follows: pair 1 = 1/2 (24 V/GND), pair 2 = 3/6 (free), pair 3 = 4/5 (RS-485), pair 4 = 7/8 (AUDIO).

The RS-485 bus may not exceed a maximum length of 1,000m (mind the voltage drop for operation voltage) and must follow a line-structure (short stub cables are permissible). Twisted-pair wiring is of special importance.

Using IY(ST)Y wiring is allowable (38400 Bd, 9N1)

Pin-Assignment Of XLRF-Type Connectors:

The pin-assignment of the MIC/LINE input's XLRF-type connector is as follows: pin 1 = screen, pin 2 = positive conductor, pin 3 = negative conductor. In unbalanced configuration, the pins 3 (-) and 1 (screen) have to be bridged inside the connection plug.
