Glossary

Pmem

Battery-protected memory.

pPPM

Peak program meter.

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

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.

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 (cross-
point) 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.

2 systems, a seg-

However, segments can be joined by repeat-

server

1. Hardware: a computer that provides
shared services to other computers over a
network; e.g., a file server.

2. Software: a program that provides data to
client programs in the same or other comput-
ers. In Jupiter systems, a “JNS server” (soft-
ware) is said to run on a “file server”
(hardware).
