3X Repeater3X Repeater—Fiber
Your 3X and AS/400 signals cover much longer distances with a 3X Repeater
on line. The Repeater carries out all the vital functions for retransmission—
each signal is resynchronized, reformatted, and filtered for noise before it is
passed on.
2.1 UTP Repeaters
Four models are available:
• 3X Repeater—UTP (IC052) with 110 VAC power supply
• 3X Repeater—UTP (IC052E) with 220 VAC power supply
• 3X Repeater—UTP RJ-45 (IC075A) with 110 VAC power supply
• 3X Repeater—UTP RJ-45 (IC075AE) with 220 VAC power supply
With a single Repeater on your lines, you can set your workstation up to
4500 feet (1376.1 m) from your controller. Each additional Repeater adds
2250 feet (685.8 m) to your line, up to the maximum distance, as determined
by the response time of your system.
The Repeater can handle screw terminal or RJ-11 connections, and works
with 22- or 24-AWG unshielded twisted pair.
2.2 Fiber Repeaters
Four models are available:
• 3X Repeater—Fiber (IC053) with 110 VAC power supply
• 3X Repeater—Fiber (IC053E) with 220 VAC power supply
• 3X Repeater—Fiber RJ-45 (IC076A) with 110 VAC power supply
• 3X Repeater—Fiber RJ-45 (IC076AE) with 220 VAC power supply
Repeaters work in pairs. You can locate each repeater up to 2250 feet
(658.8 m) from its controller or terminal, while your Repeaters may be
separated from each other by distances of up to 8200 feet (2499.4 m).
You can also cascade Repeaters to drive signals even further. Each
additional Repeater adds 8200 feet to your line.
The Repeater uses 50-, 62-, or 100-micron fiberoptic cable terminated by
ST connectors. For workstation and controller connections, it can handle
screw terminal or RJ-11 connections, and works with 22- or 24-AWG twisted
pair.
2. Introduction

CHAPTER 3: Installation—UTP Repeaters
9
3.1 General
Before you install your Repeater, check the contents of the carton. In
addition to this manual, the package should contain an undamaged Repeater
unit. If it has been damaged, call your sales representative for a replacement.
When you install the Repeater, you should follow all customary precautions
for working with electrical equipment. Make sure there’s no current flowing
within your workstation, your controller, and your cable by shutting off power
to your devices before you begin.
The site requirements for the Repeater are minimal. It should sit in a flat,
stable, dry site that affords ample clearance for all connections, and has an
AC outlet within 6 feet (1.8 m).
3.2 Preliminary
To get the best performance from your repeater, you should check the
following:
• Your cable. It should not have any bridge taps, and the wires of the twisted
pairs should be grouped, not separated. You should avoid using flat silver
satin cable for long-distance runs — it is highly vulnerable to noise and
may cause intermittent problems with transmissions.
If you use multi-pair cable, you should use bulk lengths of 100 feet
(30.5 m) or more, and you should avoid connecting multiple services
under the same sheath.
• Polarity. You should make sure that wiring polarity between the host
and your workstations is straight-through. The Repeater is sensitive
to polarity reversals.
• Termination. The last workstation on the host should be properly
terminated.
• Configuration. Your system should be able to recognize all the
devices that are on-line.
3.3 Procedure
After you have checked your site, set your Repeater in place—no more than
2250 feet (685.8 m) from your controller, and no more than 2250 feet from
your workstation.
Make sure you can distinguish between the tip lead and the ring lead on
the balun that leads to your controller. When you attach your cables to the
repeater, the tip lead of the balun will contact the tip lead of the connector
marked “CTRL,” while the ring lead of the balun will contact the ring lead of
the same connector. The same arrangement will hold for the balun that leads
to your terminal, and the connector marked “TERM.”

3X Repeater3X Repeater—FIber
Plug the Repeater into your outlet. The green LED, marked “Power,”
should glow. If it does not, check your power supply, and then check
with your technical representative.
At this point, you should follow the steps given under one of the two
headings below, depending on which attachment method you prefer.
Figure 1 applies to both methods.
To Use Screw Terminal Connectors
1. Strip 1/4” of insulation from both lengths of twisted-pair wire
(controller and workstation)
2. Connect the wires coming from the controller to the block marked
“CTRL” and tighten the locking screws.
3. Connect the wires coming from the workstation to the block marked
“TERM” and tighten the locking screws.
4. Check that the tip and ring contacts have not been crossed.
5. Turn on your workstation. The “CTRL-SYNC” and “TERM-SYNC”
LEDs should flash.
6. Your unit now should be operational. You should see the sign-on screen
from your system.
To Use Modular Connectors

CHAPTER 4: Installationn—Fiber Repeaters
4. Installation—Fiber Repeaters
4.1 General
Before you install your Repeater pair, check the contents of the shipping
cartons. In addition to this manual, each package should contain an
undamaged Repeater unit. If it has been damaged, call your sales
representative for a replacement.
When you install the pair, follow all customary precautions for working
with electrical equipment. Make sure there’s no current flowing within your
workstation, your controller, and your cable by shutting off power to your
devices before you begin.
The site requirements for your Repeaters are minimal. They should sit
in a flat, stable, dry site that affords ample clearance for all connections,
and AC outlets should lie within 6 feet (1.8 m).
4.2 Preliminary
To get the best performance from your Repeater pair, you should check
the following:
• Your cable. Your fiberoptic cable and the cable that leads from your
controller and workstation should be in top condition, with all connectors
secure and no breaks. You should not use flat silver satin cable for your
controller or terminal connections, since it is highly susceptible to noise.
• Polarity. You should make sure that wiring polarity for your Repeaters
is straight-through. They are sensitive to polarity reversals.
• Termination. The last workstation on the host should be properly
terminated.
• Configuration. Your system should be able to recognize all the devices
that are on-line.
4.3 Procedure
After you have checked your site, set your Repeaters in place—no more than
2250 feet (685.8 m) from your controller, no more than 2250 feet from your
workstation, and no more than 8200 feet from each other.
Make sure you can distinguish between the tip lead and the ring lead on
the baluns that lead to your controller and workstation. When you attach
your cables to the repeater, the tip lead of the balun will contact the tip lead
of the connector marked “CTRL TERM,” while the ring lead of the balun
will contact the ring lead of the same connector.

CHAPTER 6: Operationn and Troubleshooting
6. Operation and Troubleshooting
4.1 Normal Operation
The LEDs indicate normal operation. The green “POWER” LED should glow,
and the two red “SYNC” LEDs should flash to indicate packet transfers. The
Repeater requires little in the way of maintenance, and can be expected to
transfer data for months, if not years with little or no attention.
4.2 Problem-Solving Checklist
You may notice a change in the performance of the Repeater for a number
of reasons. The checklist below can eliminate some of the common causes
of trouble. When you have exhausted these solutions, call your technical
support representative.
CAUTION
Don’t try to repair the Repeater yourself. There are no user-serviceable
parts within the Repeater. If you open the case, you may harm yourself,
damage your equipment, or compound the problem with your Repeater.
• All LEDs remain dim
Check your AC plug and your power supply.
• “SYNC” LEDs won’t flash
Check your cable connections. Tighten any loose wiring on your
Repeater, your controller, and your workstation. Make sure your
baluns are in working order.
Check the polarity of your lines. The Repeater is sensitive to reversed
polarities.
Make sure that your fiber cables are undamaged, and your connections
are secure and free of dust.
• Noisy or corrupted data
Replace any bridged cables, and, if possible, replace any flat silver satin
cable by unshielded twisted-pair cable. Flat silver satin cable is quite
vulnerable to interference.
