WARRANTY
All fiber optic transmission systems, products and accessories
manufactured by Liteway, Inc. and its subsidiaries are fully tested
prior to shipment and are warranted against defective materials
and workmanship for a period of five full years from the date of the
original shipment. Should a problem occur, a Return Material
Authorization Number (RMA) must be obtained from Liteway Inc.
at [phone] and the item returned to Liteway, Inc. 166
Haverford Road, Hicksville, NY 11801, USA, prepaid. Liteway Inc.
will then, at its option repair or replace the defective item.
Liteway, Inc. maximum liability under this warranty is limited to the
cost of the defective item only. No contingent liabilities of any kind
are either assumed or implied.
Any items returned to Liteway, Inc. that have been misused,

by unauthorized personnel will not be covered by this warranty.
Any non-warranty repairs required will be quoted at the current
rate for such services.
Important Notices
CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All -7,-8, and -9 Models use laser diodes. These solid-state laser
diodes are located in the optical ports of these units. Laser diodes
produce invisible radiation that may be harmful to human eyes.
Never look directly into the optical port of any fiber optic unit
designed to operate with single-mode optical fiber.
NOT FOR LIFE SUPPORT SYSTEMS
Liteway, Inc. does not authorize or warrant any of its products or
accessories for use in critical life support systems or applications
of any kind.

Installation Instructions
The diagram below shows the typical installation IRIG system that
uses the IRGM-8004 for IRIG or PPS distribution.
The IRGM-8004 provides four electrical outputs. Multiple IRGM-8004
units may be “daisy-chained” when more than 4 output channels are
required.
Power Terminal Block Connections
Pin Function
1 Alarm output for use with optional Alarm Sensing Unit ALM-1000. No other connections should be made to this
terminal
2 +11 to 24 DC or AC Volts input
3 AC or DC return (Common to Housing)
Be certain to check all connections, settings and voltages before
applying power

Indicator Lights
Indicator Lights when
Pwr Proper power is present.
Alrm The loss of signal alarm is activated and there is
no IRIG or PPS signals present to transmit.
Sig A data signal is being received.
Note that for very low data rates such as the 1 PPS signal the Sig
LED lamp may blink at the data rate. This will not affect any of the
output signals at all.
Front Panel DIP Switch
Dip switch #1 is used to turn the alarm function ON and OFF.
Dip switch #2 is used to set the input coupling to AC or DC.
For very low data rates it is important to use the DC coupled position
of the DIP switch.
For signals riding on a DC level the AC coupled position will eliminate
the DC level portion of the signal but may not operate properly at very
low data rates.
