The Access Bank II allows the user, from a remote site, to monitor the signaling state of the Signal
Leads for the various data ports that are provided. If the signal on the Lead is active high, it is shown
in the color blue; otherwise it is not lit. This is useful for diagnosis of the data ports. In addition, the
various LEDs on the front panel are also displayed. This screen auto-updates at a default rate of once
every 5 seconds, which you can change, or turn off, with the slide control.
The Battery State LED indicates the status of the Access Bank II internal battery. When the LED is
on, or Green, the battery is OK, or present. If the battery is dead, or not present, the LED is off, or
gray.
