The Base Station Link Mode status appears on the Home Screen above the power level indication for
transmitter 1 (T1). The letter M stands for Master and S for Slave.

The Base Stations are connected together via the Base Link Jack (see Figure 3 Base Station Rear Panel)
and a standard RJ-45 network cable (straight-through only). The maximum Base Link cable length is five
feet. While longer cables may work, full functionality is not guaranteed for cables longer than five feet.
Example Setup Procedure for Base Link with Six Base
Stations:
1. Choose a Master Base Station and set it up as Master via the LINK SETTINGS in the main menu
(see Base Station Link Modes section). In the same manner, the other Base Stations need to be
set to Slave.
2. With all Base Stations powered off, connect the Base Stations together via the Base Link cables
in the following manner:
a. Master OUT  Slave #1 IN
b. Slave #1 OUT  Slave #2 IN
c. Slave #2 OUT  Slave #3 IN
d. Slave #3 OUT  Slave #4 IN
e. Slave #4 OUT  Slave #5 IN
f. Slave #5 OUT 
Slave #6 IN
3. Power ON all Base Stations in the order of Master first, Slave #1 second, Slave #2 third, etc. It is
not necessary to wait for each Base Station to completely finish booting prior to pressing the
power button for the next. Powering on the Base Stations in a different sequence can cause
Slave units to lock up, depending on the order. If a lock-up occurs, hold the power button for
approximately 10 seconds to force a power down.
NOTE: Powering off a system or adding/removing a Base Link cable during operation is not
recommended, and at minimum will cause systems to reboot. In the above six Base Station Base Link
example, removing the Base Link cable from a Slave unit, e.g. Slave #3, will cause every slave down the
chain (e.g. 4, 5, 6) to crash, which may require a manual reboot to resolve. Powering off a base station
in the chain will have a similar effect. To power down a number of systems in Base Link Mode, start
with the end of the chain. In the above example, power off slave #6 first, followed by slaves 5-1, until
finally ending with the master unit.
When Base Link cables are connected, all units are synchronized to the same system reference clock,
which is passed unit-to-unit over the Base Link cable. This is automatic and not user controllable. When
a unit is powered on, the internal electronics check for the presence of an external reference clock. If
the external clock is detected, the system boots using the external one. If the external clock is not
detected, the system boots from its own internal clock. Whenever the external clock is present, the
