Installing the Brain Board on the
Mounting Rack
the 50-pin connector. The figures on the previous page show how
to install the brain board on the mounting rack. When properly
installed, the B1 (digital) brain board extends away from the rack,
while the B2 (analog) brain board covers up the communications
and power wiring on the rack.
Both the mounting rack and the brain board are supplied with
permanently attached standoffs. All the standoffs should be
secured for maximum physical strength. Be sure to leave sufficient
space between adjacent units for the I/O wiring.
Installing I/O Modules
devices is removed before installing or removing I/O modules.
For specifications and wiring information on modules, see the
module’s data sheet.
Communication Cables
communications. Although you may elect to use other cables, keep
in mind that low capacitance (less than 15 pF/ft.) is important for
high-speed digital communication links. The cables listed below
are all 24-gauge, 7x32 stranded, with 100-ohm nominal impedance
and a capacitance of 12.5 pF/ft.
depending on your application needs. All will yield satisfactory
results. It is recommended that you choose a cable with one more
pair than your application requires. Use one of the extra wires,
rather than the shield, for the common.
Installation and Wiring (continued)
The B1 or B2 brain board plugs into the mounting rack using
The unit can be mounted in any attitude on any flat surface.
CAUTION! Be sure that all power to unit and to the controlled
Input and output modules can be installed in any rack position.
The following cables are recommended for RS-485/422 serial
Select from the following four-, three-, and two-pair cables,
Four-Pair:
• Belden P/N 8104 (with overall shield)
• Belden P/N 9728 (individually shielded)
• Belden P/N 8164 (individually shielded with overall shield)
• Manhattan P/N M3477 (individually shielded with overall

modes and for proper termination and biasing. When wiring a
series of Optomux units, always think of the previous Optomux unit
as the host.
