Appendix D: Serial Port Setup and

Operation

Applies to ACU1002A, ACU1008A and ACUSREM only

The default settings for serial extension (9600bps, 8 data bits, no parity, 1 stop bit, RTS/CTS
and DTR/DSR loopback) are suitable for the majority of applications. This appendix
describes how you can adjust the baud rate and hardware flow control for specialist
applications.

Serial Interface Setup and Operation

You can configure the baud rate and flow control protocol using jumpers on the serial
daughter board (see Figure 18) in the Remote and/or Local Units.

1.

Disconnect the unit’s power supply.

2.

Open the unit by unscrewing the two screws on each side of the case.

3.

Locate the serial daughter board.

The following sections describe how to adjust the baud rate and hardware flow control
protocol. When you have finished, replace the unit covers.

Figure 18

Position of Baud Rate and Flow Control jumper blocks on
Serial Daughter Board

The circuit board has several jumper blocks in addition to
those shown in Figure 18. Do not adjust any of these settings
as you will cause the extender to operate incorrectly.
