Base Station to Base Station Wiring
In any site with two base stations, the wiring between the two stations should be
completed as follows and as shown in Figure 10:
Important Note:
Interconnected base stations must be the same revision level.
•
Interbase 1 terminals from base 1 connect to Interbase 1 terminals from
base 2.
•
Interbase 2 terminals from base 1 connect to Interbase 2 terminals from
base 2.
•
IN terminals connect to OUT terminals of the same polarity.
•
GND terminals connect to GND terminals.
•
UART_TX terminals connect to UART_RX terminals.

Auxiliary Intercom
An auxiliary intercom is a wired communication system that can be used in the
event of base station failure. Figure 11 shows where the connections are made
for a 3M™ Wired Intercom Systems Classic Series Model D15. You can use a
different brand of intercom system, but the wire color coding will be different,
so you will have to determine how to wire the systems together by following the
terminal labels.
