2.2.2 Communication
Connectors
Connecting the 2103 Modem module involves uncapping and
capping communication connectors. When a communication con-
nector is not in use, the connector should always be capped. The
cap will seal the connector to prevent corrosion, and will improve
communications.
When a communication connector is in use, store the cap on the
holder next to the connector. The communication connector will
be sealed by its mating connector.
Detailed instructions and photos can be found in your 2150 or
2110 instruction manual.
CAUTION
Caps PUSH ON and PULL OFF . Do not rotate the caps to
remove them from the connectors.
Note
For modules to correctly stack and lock together, protective
caps between the modules must be stored on the holders.
2.2.3 Stacking Modules The 2103 Modem Module can be located anywhere within a stack
of up to three 2100 Series networked modules. It will draw its
power from the battery module located in the stack.
To connect the 2103 with a 2100 Series module, refer to the fol-
lowing instructions.
1. On the top of the 2100 Series module, remove the cap and
stow it on the holder. This exposes the communication con-
nector on the module.
2. Inspect the module’s communication connector. It should
be clean and dry. Damaged O-rings must be replaced.
3. Unlock the 2103’s latch by pressing in on the latch release
(right side).
4. Underneath the 2103, remove the cap from the lower com-
munication connector and stow it in the holder.
5. Lock the latch. Locking the latch correctly seats and aligns
the lower cap in its holder.
6. Position the 2103 over the 2100 Series module. Align the
connectors and lower the 2103 onto the other module.
7. Unlock the 2103’s latch by pressing in on the latch release
(right side).
8. Firmly press the modules together and lock the 2103’s
latch (left side).
The communications indicator will blink during the start-up
routine to indicate the 2103 is operating.
