ACTIVITY
The activity light indicates if there is activity on the EnergyAxis transceiver antenna.
• It will blink Red whenever RS-232 data is received.
• It will flicker Green whenever RS-232 data is read from the transceiver.
• If the transceiver is both receiving and reading, the Activity indicator will
appear as Amber.
This includes communication with the transponder and the CPU.
This indicator should flicker whenever the EA_Mobile is in reading mode. It’s
flickering becomes more solid when transmitting and receiving data from
transponders.
Fuses
The EA_Mobile contains two internal fuses accessed from the back panel (Figure
