Installation and Mounting

A prepared 3U slot in a 19" rack, or other Intermas−compatible enclosure, is required for mount-
ing the A6825 interface card. The slot must be fitted with a 48−pin plug connector (DIN 41612,
design F 48 M). The pin assignment is listed in the following table.
2 UB+ (+ 24V)
4 RS485 bus line 1 A (Port 3) RS485 bus line 1 GND (Port 3) RS485 bus line 1 B (Port 3)

This is done with plug−in jumpers, on the interface card. The figure shows the position of the
jumpers for the 6 RS 485 bus lines.
