2.3.4 Operational
Test
The repeater can be tested using the same sequence as the base unit described in section 2.2.5.
Turn the unit ON using the front panel power switch. Ensure the power LED (green) is
illuminated. Install the correct antenna for the proper frequency.
2.3.5 Usage
2.3.5.1 Once the Repeater is turned ON, the radio is immediately enabled to receive RF signals
provided:
•
They are in the same frequency
•
The PAM-TRX and Base are in the same channel number
•
The PAM-TRX and/or Base are set in the broadcast mode correctly for DT and
masking.
•
The unit send and receive addresses are compatible with the network (if not in
broadcast mode)
2.3.5.2 If a “good” RF signal is detected, the radio checks the DT parameter and retransmits
the packet with its own DT. Data that has already been repeated to the base is ignored
to reduce over-the-air congestion and continuous loop transmission.
2.3.5.3 The front panel red LED blinks for every packet of data received and the green LED
blinks when the packet is transmitted.
2.3.6 Battery
The Repeater uses a standard 9 VDC alkaline battery. The battery is accessible by removing
the back cover of the enclosure. Battery life is expected to be a minimum of 2 hours of
continuous use with full transmitter load (approximately 70 PAM-TRX within range
transmitting at 4 seconds interval).
An optional NiMH rechargeable battery (i.e.; Energizer brand NH22) can be installed. This
type of battery will provide about 1 hour of back-up time but is adequate for many cycles.
The unit continuously monitors the battery voltage. If a low battery condition is detected, the
power LED will blink at approximately 1-second intervals to indicate the battery must be
replaced (or recharged, if the option is installed).
