Voyager UTP Extender
Serial Addendum

Voyager UTP Extender Serial Addendum
The default settings for serial extension (9600bps, 8 data bits, no parity, 1 stop bit, RTS/CTS and
DTR/DSR loopback) should be suitable for the majority of applications. This addendum 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 1) 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.
Note: The circuit board has several jumper blocks in addition to those shown Figure 1.
Do not adjust any of these settings as you will cause the extender to operate incorrectly.

Baud Rate
You can set the baud rate for serial communication across the extender units at 19200, 9600 (default)
or 1200 baud.
All Local units are supplied with the baud rate preset to 9600 / 19200.
All Remote units are supplied with the baud rate preset to 9600.
Changing the Baud Rate on the Voyager UTP Remote Unit
All Remote units are supplied with the baud rate preset at 9600.

Use this procedure if you want to change the baud rate.
1. Locate the Baud Rate jumper block in the Remote unit.
2. Set the jumper to the required setting as shown in Figure 2.
Ensure that the jumpers are set correctly on both the Voyager UTP Local & Remote units

Use this procedure if you want to change the baud rate.
1. Locate the Baud Rate jumper block in the Local unit.
2. Place the jumper over the posts as shown in Figure 3.
3. Set the hardware flow control jumpers in both Local and Remote Units to RTS/CTS Flow
Control across CAT5 Link as described below.
Ensure that the jumpers are set correctly on both the Voyager UTP Local & Remote units
This mode will support most, but not all, serial mice and trackball devices.
In most cases, we recommend that you use PS/2 mouse devices with the Voyager UTP extender. If
your have a PC that does not have a PS/2 mouse port, then use a PS/2 Mouse on the remote unit and
use a PS/2 to Serial mouse converter (2146-00C) on the Voyager Local Unit to connect to the PC
Note: The drivers supplied with certain Wacom Graphics Tablets dynamically alter the
baud rate and cannot be used with a Voyager UTP Extender system. There is a version
of the driver available with a fixed baud rate. Please contact Technical Support for more
information.
Hardware Flow Control
The daughterboard’s in both Local and Remote units have a series of jumpers which allow the
selection of alternative hardware flow control schemes across the CAT5 link. Most applications will not
require hardware flow control across the link, and therefore the flow control jumpers are set to
loopback by default and should not need adjustment.
The following diagrams show how the jumpers may be set for various flow control schemes.
Please contact Technical Support if you are unsure about serial port handshaking methods.
