BER

1.0E-6 to 9.9E-3 – Indicates the BER level

FREQ

406.000000 to 470.000000 MHz – Displays

the central frequency of the operating

channel

CHAN

1 to 9601 – Displays the selected or current-

ly scanned frequency channel

TEMP

-30°C to 100°C – Displays the temperature

inside of enclosure

SYNC

1 – Indicates the established link,

0 – if link is not established yet

MODE

AUTO – Indicates Automatic scanning

mode

FHOP – Indicates Frequency hopping mode

FIXED – Indicates that the radio modem

cates all values:

TTL_IN1 = 0

TTL_IN2 = 1

RSSI = -110 dBm

BER = < 2.3E-5

FREQ = 140.000000 MHz

CHAN = 10

TEMP = 70C

SYNC = 1
MODE = FIXED

Note:

The indicated receive signal strength (RSSI) is equal to

-147 dBm if there is no signal received from transmitter.
