LED Description
IN RANGE
With a client transceiver, it lights if the client transceiver is in range of a server transceiver
with the same system ID and channel number. With a server transceiver, it always lights
when the server is powered in normal mode and is ready to accept data.
Status 1
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.
Status 2
Lights when the Write Enable pin (AC4424 / 5124/ 3124 / 1524) or GI1 pin (AC4490 /
4486 / 4790 / 4868) goes low. Controlled by WR ENABLE and Gen IN 1 buttons.
