ROUBLESHOOTING
Issue Solution
No lights on the SDK board.

Check the power connection. The VCC LED should be lit when
power is applied to the serial board.

Ensure that there is nothing shorting the VCC to GND and that
the radio is properly seated into the interconnect board.

Ensure that all jumpers are installed correctly.
Radio EEPROM cannot be read
by the .exe file.

Verify that power is applied and that the serial/USB cable is
connected to the serial board and the PC. Try resetting the radio
with the Reset button.

Verify that the correct serial/USB port is selected in the software
(Port 1 or Port 2).

Verify baud rate and port address on the PC Settings tab.

Ensure that the Program Mode/Normal Mode switch is set to
Normal Mode and Read/Write with AT Commands is selected on
the PC Settings tab.

Check to make sure the FORCED CONFIGURATION jumper is in
the correct position.

Verify the COMM SELECT jumper setting.
Writing to the EEPROM fails.

Press and hold the Write Enable button before writing to the
EEPROM if using the AC1524, AC3124, AC4424, and AC5124
product families. Reset the radio (using the Reset push-button)
before retrying.
EEPROM can be read/viewed
with the OEM software, but data
cannot be sent between the two
transceivers using the .exe file.

Ensure that the Status 1 LED is not turned on. If so, find out
what is driving RTS Low (and turning on the Status 1 LED); either
slide the Program Mode/Normal Mode switch to Normal or
cause RTS to go High.

If the Status 1 LED is not lit, reset both radios.

Make sure both transceivers have the same Channel Number
and System ID (if applicable).

Check all cables and connections.

Ensure that one radio is a server and one is a client (excluding
AC4790).

Check radio addressing.

Ensure that the radios are separated by at least ten feet.

Make sure the In Range LED is lit on both transceivers.
Packets can be sent between
both radios using the .exe file,
but cannot be sent from
software or hardware not
supplied by Laird.

Use the Hardware section of this guide to determine if a null-
modem adapter is required for interfacing to the hardware.

Ensure that the baud rate of the radios matches that of the OEM
Host hardware.

Ensure that the Status 1 LED is not turned on. If so, find out
