INSTALLATION
Unpacking
a. Visual Inspection – Before unpacking, a visual inspection should be conducted
in order to detect any physical damage to the equipment. Any evidence of the
damage should be noted and reported immediately.
b. Unpacking – Place shipping container on a flat surface, cut straps or tape,
open top. Take out each item carefully and place securely on a clean flat surface.
Return all packing material into a container (foam, boxes, etc.), close and store
away for future reuse.
c. Inspection – Inspect each item for any apparent damage, any evidence of
damage should be noted and reported immediately.
d. Content – Review the content; the following items should be included:
(a) OmniMux 400 Unit
(b) One (1) Power Unit
(c) User Manual (this document)
e. Please note any missing items or discrepancies and report them
immediately.
SITE REQUIREMENTS
Power
A power outlet 115 Volts/60 Hz (230 Volts/50 Hz) should be available within 5 ft. of
the unit.
Cabling
a. Twinax - Use standard IBM 7362229 or equivalent.
b. UTP - Must be a level 3 type or better in order to maximize the equipment’s
performance (100 +/- 15 ohms, 24 AWG solid copper, 7.8 db per 1,000 ft. @ 1 MHz
attenuation or better). Lower grade wiring will operate with downgraded
performance.
Use either an RJ45 connecter with pins 4, 5 active or an RJ11 with pins 3, 4
active. The polarity of the UTP will be selected by the appropriate Polarity Control
Switch (Host Links or Mux link).
c. Fiber - Use multimode glass fiber sizes of 50/125, 62.5/125 or 100/140 micron.
Baluns
Baluns must meet level 3/twinax impedance specification. The active signals must
be 4, 5 when using RJ45 and 3, 4 when using RJ11. The balun polarity will be
compensated by the appropriate Polarity Control switch (Host links or Mux link).
Mounting
Secure the OmniMux 400 main chassis to either a flat surface (if tabletop) or to a
standard 19” rack if rack-mountable.

CONNECTING THE HOST (LOCAL SIDE)
Twinax/UTP
Connect one Host Link (port) to the host either directly using a twinax cable
(twinax models) or a UTP cable (UTP models) via an RJ11 or RJ45 connector.
Observe and monitor the host’s link activity green LED for at least 10 seconds.
The LED blinking indicates that the host is attempting to poll the devices
connected to it and that the host link quality is adequate.
When using UTP, if no LED blinking is observed within 10 seconds, toggle the
“Host Links 0-7” polarity control switch (switch one in the Function Control Switch).
No LED blinking within 10 seconds might indicate a faulty or miswired cable, too
long a cable run, or an incompatible balun (different pin configuration). A red LED
blinking might indicate either an impedance mismatch (too many twinax segments,
poor cable quality), or too long a distance.
If host activity is observed, repeat connection for all desired host link cables.
Function Setup (Host side)
The host side OmniMux 400 should be configured as a Mux. This is done by setting
switches 4, 5 (in the Function Control Switch) to up, down positions, respectively
(refer to Figure 2.2)
Connecting the Mux Links
When using the UTP model, connect the fiber or the UTP cable. When using the
twinax model, connect the fiber or twinax cables. Either one of the two links may be
connected.
When connecting the fiber cables, note which cable is connected to the Transmitter
side (TX) and which to the Receiver side (RX). This information is vital for the
correct connection on the distant site OmniMux 400 unit.
Other Switch Settings
No other switch settings are required on the Multiplexer side.
Connecting the Devices (Distant Side)
Select the desired function for the Distant Side using Function switches 4, 5. You
may use the Distant Side in either Demux, Demux-Star or Star function. Refer to
Figure 2.2 for switch settings.
Connecting the Mux Links
When using a UTP model, connect the fiber and/or the UTP cable. When using a
a twinax model, connect the fiber and/or twinax cables. Either or both of the two
links may be connected.
a. Fiber – When connecting the fiber cables, make sure to connect the Host side
Mux Transmitter side (TX) into the Distant Devices Receiver side (RX), and vice
versa. After connecting the fiber, observe the Link Activity LED for at least 10
seconds. Its blinking indicates that the Host is attempting to poll the Distant
Devices.
