― Modem Firmware Version. Displays the modem firmware version of the unit.
― Radio Firmware Version. Displays the radio firmware version of the unit.
― RSSI from RF-MAC. Displays the Received Signal Strength Indication (RSSI) from the unit with the MAC address
displayed. The RSSI displayed range is from approximately -50 dBm to
-120 dBm. At signal strengths greater than -50 dBm, the radio will still operate but will not display an accurate RSSI
value.
― SNR from RF-MAC. Displays the Signal-to-Noise ratio from the unit with the MAC address shown. The SNR is defined as
the ratio of signal power to background noise power corrupting the signal. The higher the ratio, the less corruptive the
background noise is.
― DC Input Voltage. Displays the DC Input Voltage for the unit.
― TX Frequency. Displays the current operating transmit frequency for the active channel. Configured in Section 4.3.3.
― RX Frequency. Displays the current operating receiver frequency for the active channel. Configured in Section 4.3.3.
― Transmit Power Level. Displays the programmed power level for the active channel. Configured in Section 4.3.3.
― Transceiver Temperature. Displays the transceiver's internal temperature in Celsius or Fahrenheit.
― PA Forward Power. Displays the actual measured forward power of the transmitter. If the measured forward power
drops 1 dB or more below the user configured power level, this line will report "(fault)". When the forward power is
within range, this line will report "(normal)". The Viper SC radio can be configured to send an SNMP trap (or alarm) if
the Forward Power goes into a "fault" state.
― PA Reverse Power. Displays the actual measured reverse power of the transmitter. If the measured reverse power
increases to within 3 dB of the user configured power level, this line will report "(fault)". When the reverse power is
within range, this line will report "(normal)". The Viper SC radio can be configured to send an SNMP trap if the Reverse
Power goes into a "fault" state.
― Power State. Reports Full (normal)/Fault. Indicates if the unit is running at full power or at a reduced power. The TX
power will foldback when the temperature is too hot or the Power Amp (PA) current is too high. In extreme cases of
high temperature or high current, the transmitter will shutdown completely to protect the radio from permanent
damage. When Viper is at Full power this line will report "(normal"). If the Viper SC's PA goes into Foldback or
Shutdown this line will report "(fault)". The Viper SC radio can be configured to send an SNMP trap if the Power State
reports a fault.

ONLINE DIAGNOSTICS
Transmission of online diagnostics may be enabled or disabled at any station or stations without affecting their ability to
communicate with other stations. Online Diagnostics can be sent anywhere, including being back-hauled. Backhaul adds to
network traffic flow and must be taken into account when designing a network. If a return flow is necessary, it needs to be
reduced substantially to have a minimal effect on the network. Viper can support up to 4 diagnostics socket connections at
once. This may be used, for instance, to carry out monitoring at a main office and at up to three separate field locations. It
is also possible one of the four connections use a serial port instead by enabling it on the Viper SC's web browser interface.
4.1.2.1.1 OUTPUT FORMAT
From a Command Prompt window, type telnet nnn.nnn.nnn.nnn 6272 and the unit's online diagnostic output will display on
the screen (where nnn.nnn.nnn.nnn is your unit's IP address in dot decimal format). The online diagnostic output is
man/machine readable, ASCII, comma-delimited format. Any reader program used (or written) must decode the VERSION
FIELD and check for type 1 as more types may be released in the future. Note: no overhead is generated in the Viper SC unit
if no online diagnostic connection is actually made.
