Figure 21. LCD display format for A500
The top left area shows the device (A500) and the installed application firmware version.
The lower left area shows the current device state (boot, conn(ected), or idle).
The flashing asterisk on the left of the <**> shows that the A500 is operating normally; the one
on the right indicates that the Ethernet connection to the host is made and communications are in
progress.
The fiber-optic loops are indicated by the numerals 1 to 5 in the top row. Flashing asterisks
indicate that the loop is active. The number below the loop is the number of devices that are
being serviced on the loop.
The display for the –R5T5 option shows loops from 1 to A. The –R10 and –T10 options show
the ten devices (rx and tx respectively), with a flashing asterisk below to illustrate activity, such
as an incoming data stream for the A500-R10.
