Verify the PC Settings. See Section 4.2.3 PC
Settings.
Make sure the CL4424 unit uses the right serial
cable. Refer to Section 2.1 RS-232.
If any other program is running and is using the
same COM port as the CL4424, close that
program and try to read the radio again.
Reset the radio by cycling power after each
unsuccessful Read.
Verify that the baud rate of the CL4424 matches
that of the CL4424 host device.
Make sure the CL4424 unit(s) is connected to
the correct COM Port.
Check the COM port settings for correct Baud
Rate. Units can have transmission errors with
Flow Control set to Xon/Xoff.
Try increasing the Maximum Transmit Attempts
(for Clients) and/or Broadcast Attempts (for
Servers) values in small increments until
communication is established.
Connect a Null Modem adapter between the
Client and its host device.
Check the Destination Address setting.
Make sure the unit is connected to power.
Cycle power to the radio.
Verify the Channel Number and System ID
settings.
Cycle power to the radio.
Read the radio and make desired changes and
then Write the radio.
