Material and Tools Required
2
For the J ‐ 202 ‐ XPR, first remove the right cover,
then the left cover, retaining the two screws that
secure each cover.
3.
For all but the J ‐ 202 ‐ XPR, remove the battery and
bracket assembly by taking out the screws
holding it in place, setting the screws aside for
later. Unplug the battery from the connector on
the JACE. See Figure 2 for an exploded view.
Figure 2 Remove battery assembly.
4.
Remove the blanking end plate for the slot you are
installing the option card into.
(Retain the blanking end plate in case the option
card must be removed at a later date.)
5.
Carefully insert the pins of the NPB ‐ 2X ‐ 485 into
the socket of the appropriate option card slot. The
mounting holes on the option board should line
up with the standoffs on the base board. If they do
not, the connector is not properly aligned. Press
until the option card is completely seated.
6.
Place the custom end plate that came with the
NPB ‐ 2X ‐ 485 over its connector (see Figure 3 ).
Figure 3 NPB-2X-485 inserted, end plate on top.
7.
Plug the battery cable into the battery connector
on the JACE (see Figure 3 for location on the
JACE ‐ 200/600).
8.
For all but the J ‐ 202 ‐ XPR, set the battery and
bracket assembly back over the option card slots,
with mounting holes aligned with the standoffs.
Screws enter holes in the battery bracket first.
Figure 4 Re-fasten screws.
9.
Place the screws through the end plate(s), and into
the standoffs on the base board. Using a
screwdriver, hand tighten screws.
10.
Replace the JACE cover or covers (J ‐ 202 ‐ XPR).
If accessory modules were unplugged from the
JACE, plug them back as before, and secure.
Wiring
Connect to an RS ‐ 485 multipoint network using one of
the 3 ‐ position screw terminal connectors, using
shielded 18 ‐ 22 AWG wiring. Refer to the TIA/EIA ‐ 485
standard for more details.
Screw terminals are minus (–), plus (+), and shield ( S ),
as indicated on the NPB ‐ 2X ‐ 485 end plate label—see
Figure 1 on page 1.
LEDs
Four LEDs are visible on the top of the NPB ‐ 2X ‐ 485
option card (cover must be removed from JACE). The
label on the NPB ‐ 2X ‐ 485 end plate notes these four
LEDs as “TX” and “RX”—see Figure 1 on page 1.
The two LEDs for each port are described as follows:
•
TX (yellow) — Transmit, indicates that the JACE
is sending data to a device connected on the
RS ‐ 485 trunk.
•
RX (green) — Receive, indicates that the JACE is
receiving data from a device connected on the
RS ‐ 485 trunk
