INSTRUCTIONS for TG-KIT LTE
Conversion of TG-7 Series to Telguard TG-7 LTE
The Telguard
TG-KIT LTE can be used to convert an
older TG-7 series device (2G, 3G/4G, or CDMA) to a
comparable TG-7 LTE model.
Pre-Installation checklist:
Four (4) standoffs.
Four (4) mounting screws.
One (1) washer.
One (1) metal plate
NEW TG-7 LTE circuit board
Terminal Blocks
Labels
Conversion Procedure:
Note: Prior to beginning the hardware conversion,
identify the type of enclosure you are dealing with. If
the P/N of the original unit ends in 001, you have a
“Legacy” unit.
A. Disconnect all power to the Telguard unit. This
includes both AC power transformer and battery.
If the unit is a Legacy device, then a metal plate
(included) is needed to convert the dual board
chassis to a single board chassis.
B. Remove the TG7 circuit card(s) from chassis by
doing the following steps:
1.
Disconnect the wires from terminal block.
2.
Disconnect the antenna (or antenna cable
if dealing with a TG-7A).
3.
Remove the antenna TNC connector’s
retaining nut and washer. Set these aside
for later use. (Figure 1)
If the unit is a Legacy 2G device, the
daughter cards are secured with small
brackets. Unscrew these brackets to
remove these cards.
4.
Remove all the screws securing the current
circuit board.
If the unit is a Legacy 2G device, you
will have four mounting screws and a
green grounding screw (Figure 2).
For other models there are only three
mounting screws in addition to the
grounding screw.
5.
Set aside these mounting screws for future
use and remove old circuit board.
For Legacy 2G devices, you may need
to first remove the Modem card. If so,
set Modem Card and bracket screws
aside for later use. (Figure 2)
6.
If you have a Legacy 2G TG-7A you must
remove the antenna bracket. (Figure 3)
