core Control System Protocol via RS-232, RS-
422, SLIP, or Ethernet.) Note: Maestro com-

TIVE ROTOCOL
refresh
Continuous repetition of switching instruc-
tions and confirmation of crosspoint status.
Reports any interruption of service – for ex-
ample, if crosspoint board is removed. When
board is replaced, automatically restores pre-
vious switch instructions.
RS-422
EIA standard which defines the electrical
characteristics of balanced voltage digital in-
terface circuits. More rugged than the earlier
RS-232 standard, which employs unbalanced
voltages. This standard does not specify a
connector type. While the Jupiter VTR / con-
trol panel bus and CC 2010 matrix (cros-
spoint) bus are both based on the RS-422
standard, the VTR / control panel bus uses 9-
pin D connectors and the CC-2010 matrix bus
uses 15-pin D connectors.
