FIRMWARE INSTALLATION
The firmware installation procedure involves installing
the latest version of the EPROM containing the GETC
operating software.
Upgrading to 344A9607G4 Software
With the release of 344A9607G4 software, both
Wideband 9600 baud functionality and Narrow Band 4800
baud functionality have been merged together. This release
also includes three new features:
• Failsoft Patch
• Wideband power monitoring
• Channel Activity Logging
In addition, this software release was designed in
conjunction with the GETC PC Programmer TQ3357
version 4.0 (344A3466G5).
NOTE
Refer to SRN1060 to determine the compatibility
of this software with the software used in other
EDACS equipment.
Multisite Digital Voice or Digital Data
Digital Voice or Digital Data applications require
installation of a Rockwell Modem. This allows the GETC
to send and receive Digital Voice or Digital Data
information, encoded as 9600 baud modem data, to the
CEC/IMC using the four-wire audio line.
Additionally, the personality option for Wide Area
Digital Voice must be ENABLED for proper operation.
This can only be done using the PC Programmer version 4
(or later).
Installation Procedure
The following procedures provide instructions for
installing the firmware when the GETC functions in a
Failsoft System, a Fully Trunked System, or Satellite
Receiver:

Failsoft Systems
Perform the following steps when installing the
firmware in a GETC connected in a Failsoft system.
NOTE
Upgrading to Group 4 software is backward
compatible in functionality with 344A9607G1 &
G2 and 19A149256G18 thru G21 software in the
Failsoft operation. However, ensure the GETC is
also upgraded to include the Turbo Board with
344A4414G4 software and Ferrite Toroid, 80C320
microprocessor (U1), and 19A704727P4 Modem
(U4 & U19).
1. Power down the channel and place the GETC into
the service position. Refer to LBI-38894 if
necessary.
2. If upgrading from 19A149256G21 (or earlier)
software, remove RAM chip U3 and install Turbo
Board. Refer to LBI-38822 for instructions.
3. Ensure Modem chips U4 and U19 are
19A704272P4. Required when upgrading to
Group 4 (or later), replace if necessary.
4. Ensure microprocessor U1 is the faster 80C320
(RYT 121 6060/A) device. This processor is
required when upgrading to Group 4 (or later).
Processor is available in Speedy Upgrade Kit
SPK9505. Replace if necessary. Refer to LBI-
38894 for installation instructions.
5. Ensure Turbo Board harness has Ferrite Toroid
installed. Toroid is included in the SPK9505
Speedy Upgrade Kit. Replace if necessary. Refer
to LBI-38822 for installation instructions.
6. Remove the old EPROM (U2) from the GETC
Logic Board.
7. Install the new EPROM into the XU2 socket, being
sure to properly orient the chip.
8. Power up the channel.
