DISTANCE EXTENDERS
These multi-purpose units have the ability to remote your receiving device up
to 4000 feet (1219.2 m) from the sending device. There are two basic types of
Extenders: serial and parallel. Each serial or parallel Extender comes in 115-
and 230-V input, output, and universal models. The Extenders are available in
kits (parallel-parallel or serial-serial), or you can order them separately to
accommodate a mixed application.
Each of the universal modules can be set to be either an input or an output
device. The non-universal modules are preset during assembly as transmitting
(input) devices or receiving (output) devices. The serial modules are switch-
selectable for either DTE or DCE application, eliminating the need for special
cables and preventing confusion in installation. Connecting the units
together has been made easier by using straight-through Category 5 cable,
connected to either the RJ-11 jack or the 4-screw terminal block.
2. Introduction

CHAPTER 3: Installation
Before you begin, make sure all equipment is off and the Extenders are not
powered on.
3.1 Serial Extenders
In serial-to-serial applications, use the charts on page 11 to set switch S2 for
baud rate, transmission speed, and termination. Set S1 for either DCE to
connect to a PC, or DTE to connect to a modem. Attach the two devices
with appropriate cable. All connections are straight-through: pin 1 to pin 1,
pin 2 to pin 2, etc. Once all connections are made, connect DB25 cables to
the equipment and power up the converters. Now power can be applied to
your equipment.
For testing purposes, a self-test has been incorporated into the serial
converter. To enable the test, S2-4 needs to be placed in the up (open)
position. When this is done, the self-test will be transmitted to the serial
port. If a PC is the receiving device, a terminal-emulation program will
need to be running.

S1 for either Transmitting (Input) Device to connect to a PC, or Receiving
(Output) Device to connect to a printer. On non-universal modules, the
function of S1 is fixed during assembly; S1 is not present on these modules.
Attach the two devices with appropriate cable; all connections are straight-
through (pin 1 to pin 1, pin 2 to pin 2, etc.). Once all connections are made,
connect DB25 cables to your equipment and power up the converters. Now

3.3 Mixed Operation
In a serial-to-parallel application or a parallel-to-serial application, the same
setup is necessary for each unit as described above. It is important to note

devices.
3.3.2 S ERIAL TO S ERIAL
1. One device must be configured as a transmitting (input) device, and one
device must be configured as a receiving (output) device.
2. The transfer rate must be the same between the transmitting and receiving
devices.
3. Each device must be configured as a DCE or DTE as appropriate for the
interfacing equipment.
4. The baud rate of each device must be set the same as the interfacing

3.3.3 P ARALLEL I NPUT TO S ERIAL O UTPUT
1. The parallel device must be configured as a transmitting (input) device,
and the serial device must be configured as a receiving (output) device.
2. The transfer rate must be the same between the transmitting and receiving
devices.
3. The serial device must be configured as a DCE or DTE as appropriate for
the interfacing equipment.
4. The baud rate of the serial device must be set the same as the interfacing

CHAPTER 4: Troubleshooting
If the unit fails to operate:
1.Is the unit powered on? If so, check to see if the power supplies are plugged
into a working AC outlet.
2.Check to see if the inter-connect wire is straight-through.
3.Make sure that one unit is set up to be transmitting and the other receiving.
4.1 Calling Black Box
If you determine that your Extender is malfunctioning, do not attempt to
alter or repair the unit. It contains no user-serviceable parts. Contact Black
Box Technical Support at 724-746-5500.
Before you do, make a record of the history of the problem. We will be able
to provide more efficient and accurate assistance if you have a complete
description, including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used,
appears to create the problem or make it worse.
4.2 Shipping and Packaging
If you need to transport or ship your Extender:
• Package it carefully. We recommend that you use the original container.
• If you are shipping the Extender for repair, make sure you include
everything that came in the original package. Before you ship, contact
Black Box to get a Return Materials Authorization (RMA) number.
