Installation and Mounting

A prepared 3U slot in a 19" rack, or other Intermas−compatible enclosure, is required for
mounting the A6151 monitor. 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.

1.5.1 Jumper RS 485

RS 485 bus operation requires an electrical terminator on the first and last bus device.
This is done with plug−in jumpers, that are on the controller board. The figure shows the position
of the jumpers.
To activate the bus terminator and to place lines "A" and "B" on the references, plug the jumpers
as shown in Fig. b). Fig. a) shows the jumper position for deactivated bus termination and open
references (delivery status).
