Jupiter L-S Series Control Panels Installation and Operating Manual 113
Glossary
numeric set
Factory-supplied configuration set used to
set up and operate the routing switcher in the
minimum possible time.
O
OPM
OUTPUT MONITOR .
override
One-button selection of an input. Override
button of a control panel is programmed to
select a particular input that is used heavily.
output monitoring
Feature of routing switcher which allows
control system to verify switcher perfor-
mance without interrupting normal opera-
tions. A separate, internal switching system
is used to switch the Monitor Output to any
output of the switcher.
P
path finding
Switching technique allowing two or more
routing switchers to operate as a system,
where each switcher can access the other's in-
puts through a number of tie lines. Be cause
the tie lines are limited, the path will be
blocked when all lines are busy. Not to be con-
fused with
THREE - STAGE S WITCHING .
PCI
Peripheral Component Interconnect, a local
computer bus standard developed by Intel
Corporation. Most PCs include a PCI bus in
addition to a more general ISA expansion
bus.
physical level
see LEVEL .
Pmem
Battery-protected memory.
pPPM
Peak program meter.
protect
On Jupiter/ series panels with a PROTECT
button: after a given source has been
switched to a given destination, and PRO-
TECT is pressed, the source for that destina-
tion can then be changed only at the panel
which protected the output.
R
RCL
GV Router Control Language Protocol (En-
core Control System Protocol via RS-232, RS-
422, SLIP, or Ethernet.) Note: Maestro com-
mands to an Encore control system use N
A -
TIVE P 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.
repeater
Device for connecting two LAN segments.
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.
