Figure 1: Option board stack
The Revenue Guard option board is not part
of this stack and is not affected by the
presence of other option boards.
The kV RSX board is installed as follows:
1. If the meter is not disassembled, follow
the disassembly instructions described
in the kV™ Meter Installation,
Operation, and Maintenance Guide
(GEH-5081).
2. Place the bezel face down on a soft,
clean surface to protect the nameplate
and liquid crystal display.
3. Remove the I/O and LP option boards if
they are present.
4.
The I/O-1 and LP-1 option boards
must not be reused with the kV RSX.
5. Select the desired mode of operation by
installing the jumper shunts according to
the following:
Figure 2: Location of mode jumpers
Figure 3: External Modem Mode
Figure 4: RS-232 Simple Serial Mode
Figure 5: RS-485 Simple Serial Mode
6. If the kV RSX Option Board will not be
combined with either the I/O or LP
option boards proceed to step 3. If the
kV RSX Option Board will be installed
with the I/O-2 and/or LP-2 option boards
proceed to the next step.
7. Place the kV RSX Option Board on a
soft clean surface and install the four (4)
nylon spacers by gently pushing them
into the four (4) holes on the board.
Do not reuse nylon spacers. When
removed, a slight rounding of the
spacer occurs which can greatly
decrease the ability of the spacer to
hold the option board firmly in place.
8. If both the LP-2 and I/0-2 option boards
are to be installed, the LP-2 option
board must be installed next. Install it
by engaging the 26 pin connector pins
between the kV RSX Option Board and
the LP-2 option board. Then, after lining
up the nylon spacers on the kV RSX
Option Board with the four (4) holes on
the LP-2 board, snap the option board
into place.
9. The I/O-2 option board may be installed
directly to the kV RSX Option Board if
the LP-2 option board will not be used
Note: The kV RSX Option Board must
always be installed as the inner most option
board (the board closest to the kV™
Meter’s main board).
