Bulletin 1400–BCU

The Bulletin 1400-DCU/BCU Communications Card supports Remote I/O

and can be optionally configured as either RS-485 or RS-232C. Remote I/O

and one of the two open architectures are active at all times. RS-232C or

RS-485 are selected by means of a jumper.

Note: Bulletin 1400–DCU is used with the Powermonitor Display Module

and Bulletin 1400–BCU is used with the Powermonitor Block Module.

This section explains the procedure for installing a universal communications

card or changing the communications mode.

The card has a jumper block to allow the user to select RS-232C or RS-485

mode. The card’s currently selected communications mode may be viewed

from the front panel of the Powermonitor Display Module, if the unit is

operating, (see Publication 1400-5.2, Chapter 3, “Field Programming”), or

by removing the card and examining the position of the jumper block.
