Linking
Before a belt station and a gateway can be connected, they must first be Linked . As a security
measure, the close-link feature requires devices to be in proximity of about 1 to 3 ft (0.3 to 0.9m)
in order to successfully link. This ensures that the units are not inadvertently linked with other
units on the premises.
Linking procedure:
1. Ensure units are within 1 to 3 ft (0.3 to 0.9m) of each other.
2. Ensure the U9110-BSW is not already connected (see Status Indication ).
3. Simultaneously (within 1-2 sec) press and release the PTT button on the U9110-BSW and
the gateway to link with.
4. Amber LED’s will flash on both devices. A momentary red LED indicates a successful
close-link.
5. Upon successful link the U9110-BSW will attempt to establish a connection with the
gateway.
6. Upon successfully establishing connection the LED will flash green, a voice alert will be
heard (see
Table 1 ), and user side-tone will be enabled (see Communication ).
7. Link and connection are now complete.
Each belt station is able to be linked to only one gateway at a time. A gateway can have up to
five belt stations linked and be connected to four of those five at one time.
Tip:
Once linked, the devices will not need to be linked again unless they are purged (see
Purging ).
Status Indications
The power button has a multi-color LED in the center which serves as a status indication for the
