Will light when power is applied to the Serial Adapter Board.
Monitors the 5V supply and lights when the supply dips below 4.8V.
Will light when the Reset line to the processor is High, resetting the transceiver.
Will light when the TXD line is Low; will flash rapidly when data is transmitted from the
transceiver to the host.
Will light when the RXD line is Low; will flash rapidly when data sent by the host is
received by the transceiver.
Will light when the 9600 Baud line is Low; shows that the FORCED
CONFIGURATION jumper is set to force the transceiver to 9600 Baud. The
transceiver must be reset before it will be forced to 9600.
If used with a Client transceiver, will light if the Client transceiver is in range of a
Server transceiver with the same System ID and Channel Number. If used with
a Server transceiver, will always light when the Server is powered in normal
mode and is ready to accept data.
Reflects the state of the Command/Data pin (AC4490, AC4486, AC4424, AC4790,
AC4868), the TE pin (AC3124, AC1524) and the Pktmode pin (AC5124). This is
controlled by the PC RTS pin when the Program Mode/Normal Mode switch is set
to Program Mode. Lights when this pin goes Low.
Will light when the Write Enable pin (AC4424, AC5124, AC3124, AC1524) or the GI1
pin (AC4490, AC4486, AC4790, AC4868) goes Low. Controlled by the WR
ENABLE and Gen IN 1 push buttons.
This varies the voltage (0 – 3.3V) presented to the AD In pin (pin 18).
Will light when the GO0 pin (pin 1) is Low.
Will light when the GO1 pin (pin 9) is Low.
When depressed, will force the GI0 pin (pin 4) Low.
When depressed, will force the GI1 pin (pin 14) Low.
