1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
5250 Repeater. A working knowledge of local area network (LAN)
operations, including familiarity with communications protocols
used on interconnected LANs, is assumed.
The 5250 Repeater
The Twinax to Fiber 5250 Repeater (5250-CV-T-F/11) extends the
signal distance between an AS/400™, S/3x, or 5x94 host and
terminal equipment.
•Distance of twinax controller to last DTE can be extended to
6 km (20,000 feet).
•Designed to support all 5250 compliant devices including
devices operating at a non-standard rate.
•UTP hot redundant backup to fiber connection can be installed,
for distances between 5250 Repeaters of up to 750 m (2500 ft).
NOTE: When the 5250 Repeater receives a 5250 data signal, the
5250 Repeater recognizes the 5250 start sequence, loads the data
into an internal buffer, creates a new start sequence, re-clocks the
data, and transmits a completely rebuilt data packet. In this way,
signal distortions caused by line length and external noise are
eliminated.
The sole purpose of this remedy shall be provided the customer with the replacement or
repair of non-conforming goods in the manner described in this Warranty statement. This
exclusive remedy shall not be deemed to have failed of its essential purpose so long as TN is
willing and able to repair or replace the defective item(s) or refund the purchase price.
TN reserves the right to inspect products claimed to be defective under warranty either at the
customer’s location or at TN’s plant. TN assumes no liability for liability charges incidental
to the adjustment, service, repairing, removal or replacement of the product, or other costs,
or the expense of repairs made outside of its factory, except when made with TN’s prior
written consent. Additionally, Transition Networks reserves the right to charge for all testing
and shipping incurred, if after testing, a return is classified as “No Problem Found”.
TN’s total liability in connection with the products and their installation to all persons and
from all causes in the aggregate, whether in contract, tort, or strict liability, shall not exceed
the amount paid to TN for the product directly related to the alleged damage. However, in
no event shall TN have any liability to a customer or any third party for products
manufactures according to the customer’s specifications.
C. Return Procedure
The customer must follow this procedure for the return of defective items:
1. Locate the serial number(s) of the item(s) to be returned.
2. Determine the date the item(s) was received.
3. Contact Transition Networks Technical Support to determine if the problem can be
corrected on site.
If not, and the product is covered by warranty, then:
•Call the distributor directly or contact TN.
•Request a Return Material Authorization (RMA).
•Ship the item, prepaid in original packaging to Transition Networks at the above
address.
•Include the RMA number on the outside of the carton and/or on the Packing List.
•Include a copy of the RMA form.
•Include a copy of the original invoice or packing list (if possible) to expedite
processing.
•The item(s) may be shipped by the customer or the distributor.
•Transition Networks will repair or replace the unit, at TN’s discretion, and cover the
cost of the return freight to the distributor or to the customer, whichever requested
the RMA number.
If the item(s) was received more than five years ago, or if the item(s) is no longer covered by
warranty for other reasons, then:
•Call the distributor or contact TN.
•Request a Material Repair Authorization number (MRA).
•Ship the item(s), prepaid, in the original packaging to Transition Networks at the
above address.
•Include the MRA number on the outside of the carton add/or on the Packing List.
•Include a copy of the MRA form.
•Include a copy of the original invoice or packing list (if possible) to expedite processing.
•Only the customer (end-user) may send the items(s) to TN.
•TN will contact the customer after the item(s) have been received, inspected, and a
cost estimate of the repair determined.
•The repair charges may be billed, with customer’s approval, though the distributor, or
on a prepaid or C.O.D. basis directly to the customer. The charges will include the
cost of shipping.
The return authorization numbers are valid only for 90 days from the date issued.

Fiber Connection
NOTE: Fiber cables consist of two separately identified cables which
may be color-coded.
To connect fiber cable between Host 5250 Repeater and Terminal
5250 Repeater:
1. Locate or build fiber cable that conform to cable
specifications and with male fiber connectors installed at both
ends. (See page 20)
2. Connect one end of one fiber cable to Host 5250 Repeater TX
connector.
3. Connect other end of that fiber cable to Terminal 5250
Repeater RX connector.
4. Connect one end of second fiber cable to Host 5250 Repeater
RX connector.
5. Connect other end of that fiber cable to Terminal 5250
Repeater TX connector.
6. Set Fiber/UTP Polarity Switches on both Host 5250 Repeater
and Terminal 5250 Repeater either to A or to B.
Optional UTP Backup Connection
To connect twisted pair cable between Host 5250 Repeater and
Terminal 5250 Repeater:
1. Locate or build twisted pair cables with the following
characteristics:
•compliant with cable specifications (See page 20)
•straight through cable configuration (See page 5)
•male RJ-11 plug connectors installed at both cable ends.
2. Connect male RJ-11 plug connector at one end of twisted pair
cable to RJ-11 connector on Host 5250 Repeater.
3. Connect male RJ-11 plug connector at other end of twisted pair
cable to RJ-11 connector on Terminal 5250 Repeater.
