Cable Connections
NOTE:
Standard length of the RS-422 cable is 16 meters (The cable length is
indicated by the dash number on the end of the part number.) The maximum
combined length of the adapter and RS-422 cables should not exceed 300 meters.
The adapter cable connects between J17 at the rear of the Kaleidoscope
Controller chassis, and the 9-pin D-type connector on the end of the RS-422
control cable. The control cable connects to J1 (Port A1) or J3 (Port A2) on
the optional Expanded Communications Module at the rear of the switcher
frame (B1 and B2). See Figure 2-14.
NOTE:
This interface requires that the Serial Communications mezzanine board
(068918) be installed on the switcher Expanded Communications Carrier Module
(064824). The Expanded Communications Carrier Module is located in slot B1
and B2 in the switcher frame.
Additional Kaleidoscope requirements are as follows: The Parallel I/O module in
the Kaleidoscope Controller must be a 068604 module (not a 068537), and the
software version installed in Kaleidoscope must be 6.0 or later.
