information presented in this manual is applicable to
EDACS SCAT stations using the MASTR II, IIe or MASTR
III repeaters. The manual provides instructions for installing
the SCAT Station GETC hardware and software, Turbo
software, and programming the system’s personality. It also
provides instructions for performing a functional checkout
of the GETC's.
DESCRIPTION
SCAT is a unique application of a GETC shelf that is
configured as an option to an EDACS Repeater. The SCAT
option allows a single repeater to alternately perform the
Control Channel or Working Channel functions. This
extends the trunked operation into difficult areas such as
ravines, tunnels, etc. and extremely low traffic density areas
such as shopping malls.
SCAT systems are available for all EDACS wideband
configurations: VHF, UHF, and 800 MHz.
The SCAT channel may be configured as stand-alone
system or as part of a multisite trunking network.
The SCAT Station GETC uses a Lightning GETC
(GETC1e) platform 19D901868G3 or G4 consisting of the
following sub-assemblies:
SCAT Station GETC:
•
Logic Board 19D904266G1 (used with Group 3
shelf) or 19D904266G4 (used with Group 4 shelf).
•
GETC Expansion Module (Turbo Board)
19D903536P1.
•
Regulator Board 19C366861G2.
•
Rockwell Modem 19A705178P1 (optional). (The
modem is required when the SCAT Station is setup
to use the Wide Area Digital option.)
•
Software:
GETC - 349A9607G5 Ver. 5.04 (EPROM media)
Turbo - 344A4414G5 Ver. 5.01 (diskette media)
NOTE
GETCs using Logic Board 19D904266G1 with
Group 5 station software must be upgraded with the
Speedy (80C320) microprocessor and Amps
Modem chips, U4 and U19 (19A704727P4). A
FerriShield Toroid (REG70469/1) must also be
installed around the Turbo Board’s harness. (Refer
to Upgrading Hardware section of this manual.)
SCAT Downlink GETC:
•
Logic Board 19D904266G1 (used with Group 3
shelf) or 19D904266G4 (used with Group 4 shelf).
•
GETC Expansion Module (Turbo Board)
19D903536P1.
•
Regulator Board 19C366861G2.
•
Rockwell Modem 19A705178P1.
•
Software:
GETC - 344A4895G5 Ver. 5.01 (EPROM media)
Turbo - 350A1121G5 Ver. 5.01 (diskette media)
•
SCAT Interconnect Cable 19C337102P1.
NOTE
In MASTR III systems, a cable (19D903880P10) is
added to allow easy access to the MIII Tx and Rx
Audio (J101). This cable is routed from the MIII
Interface Board J101 to the Downlink GETC TB10
pins 1, 2, 3, and 4.
SOFTWARE UPGRADES
The GETC software product is continuously being
improved and upgraded to include new features. The
following paragraphs provide brief descriptions of the new
features introduced by recent software releases. Information
is also provided when hardware or software issues affect the
GETC’s configuration.
For a complete description of the new or enhanced
features and its use, refer to Software Release Notes (SRN)
for the specific software release. In example, for
349A9607G4 software refer to SRN1060-4, For
349A9607G5 software refer to SRN1060-5, etc.
