some care will need to be taken when assigning particular beltpacks to
locations and users in the area covered by the system to most
efficiently use the transceiver/antennas.
Use a specially wired four-pair CAT-5 data cable to connect the BASE
LOOP connectors on the two bases together.
This cable must have a
maximum length of 1 meter (3 feet) . The pinouts of this cable are
shown in the following table.
Table 4-6: Pin Assignments for Base Loop Connectors
Note: It is recommended that shielded CAT-5 cable is used.
CONNECTING TO TRANSCEIVER/ANTEN-
NAS (CEL-TA)
CONNECTING ONE TRANSCEIVER/ANTENNA
(CEL-TA) DIRECTLY TO A TRANSCEIVER PORT
A CEL-TA transceiver/antenna connects to the transceiver port on the
CellCom 10 base station using a standard 4-pair CAT-5 data cable with
RJ-45 connectors. It may be located up to 1,000 meters from the base
station if 24AWG cable is used or 500 meters if 26AWG cable is used,
creating a coverage area for five CEL-BP wireless beltpacks in that
location. The port is able to provide the required power to the
transceiver/antenna at a distance of up to 300 meters (approximately
900 feet); beyond that distance, the CEL-TA transceiver/antenna must
be locally powered via its in-line external universal power supply.
Note: It is recommended that shielded CAT-5 cable is used.
To know that a CEL-TA transceiver/antenna is active, observe the
green power LED and the yellow signal LED on the face of the unit
where the RJ-45 connector is connected. Both must be lit. Also,
