Interface Link Status - Vivotek M500AG User Manual

41. Interface Link Status

Real-time link statuses of all interfaces are shown in the menu.
- System Up Time
Display how long 500AG has been operating since last boot-up.
- Temperature
The temperature inside the waterproof housing.
- Interface Status
Indicate the interface is ENABLE or DISABLE.
- Type
Indicate the wireless interface is configured as an AP or wireless station.
- Tx-Power
Transmit power of wireless interface set in SMT-12.
- Data Link Rate
Real-time data transmission rate. When Data Link Rate in SMT-12 is set, it displays here.
Otherwise, when it is set as AUTO in SMT-12, Data Link Rate here indicates the maximum
transmission rate available, and can be used as an indication of link quality. The maximum link
rate according to 802.11a/g is 54Mbps. Only available when the interface is set as an AC.
- Link Quality
Calculated from RSSI, signal and noise level to indicate the quality of the communication link in
percentage.
- Channel
The channel used by the wireless interface.
- Signal Level
A -70 ~ -50dBm signal level is recommended for a good connection. Too low a signal, the wireless
link between AP and AC can not be established. Too high a signal level, the power amplifier at the
receiver might be forced to operate in saturation region and distorts the signal waveform. Hence
likely to result in reception error. Since the signal level at AP is defined by the user, Signal Level is
only available when the interface is set as an AC.
