3.2.2 SNMP Management Information Base (MIB)
The Technalogix.mib file allows access to the following data via the SNMP
protocol:
Read Only
Pallet Supply Voltage - voltage level (Vdc)
Temperature - temperature in (°C)
48V Current - current on high voltage bus (Adc)
Attenuation - attenuation level
Reflected Level - reflected level as % rated full scale
Forward Level - forward level as % rated full scale
RF Input Level - input level as % rated full scale
Deviation - modulation level as %
Left Level - left audio input level shown as dB
Right Level - right audio input level shown as dB
Serial Number
Model Number
SNMP Error Flag - error flag, also for trap (see below)
VSWR Flag - error flag for high VSWR
Overdrive - error flag for overdrive
Temperature Flag - error flag for high temperature
Preemphasis - 0,25,50 or 75 us
Read/Write
Reset - 1 Reset System, 0 Normal
Carrier On - 1 Carrier On, 0 Carrier Off
Carrier Up - 1 Increase Carrier Level for AGC target 1%
Carrier Down - 1 Decrease Carrier Level for AGC target 1%
VSWR Trip point - 1-8 for 1.1:1 – 1.8:1
Frequency - 880 – 1080 for 88.0 to 108.0 MHz
Change Preemphasis - rotate through 0,25,50, and 75
AGC Setpoint - set target output power 0-100% rated power
Analog/Digital - 1 Analog audio input, 2 Digital audio input
Digital Input - 1 AES 2 SPDIF 3 TOSLINK
Analog Input - 1 Mono 2 Stereo 3 MPX
Left Attenuation - 0 – 79 dB Attenuation (shows 100dB when
channel disabled)
Right Attenuation - 0 – 79 dB Attenuation (shows 100dB when
channel disabled)
MPX Attenuation - 0 – 79 dB Attenuation (shows 100dB when
channel disabled)
SCA1 Attenuation - 0 – 79 dB Attenuation
SCA2 Attenuation - 0 – 79 dB Attenuation
