Radio Modem HN-210
A few things to try:
1. The green light on the HN-232 device should always be on. The amber light on the HN-232 device should only be on when communicating to the sign (or have an error message on the computer screen). Please note that when the power is reset to the HN-232 device the amber light may be on and may not go out until you communicate. This most likely will cause the communications to fail on the first try. Do not change any setting and try to communicate once more. The amber light should turn off after the first failed attempt.
2. Open the Windows Device Manager and open Ports (COM and LPTs) and look for the devices that have a comport associated with it such as (COM1). If more than one, make note of them as you may use them in testing.
3. Open the Windows Device Manager and open Mice and other pointing devices and if “Microsoft Serial Ballpoint” appears in list, right click on it and choose “disable” do not choose uninstall (the radio device will not appear elsewhere in device manager).
4. Open the sign software and open Options, Software Configuration. In the Sign Communication area select Radio (Radio Modem Hook-Up).
5. The default Modem String is wn0 wp0 and this most likely will NOT work with your sign. If you do not know your modem string give us a call 800-445-9206 or email us.
6. Change the COM Port Speed to 38400 Baud. This may need to be changed if you are not able to connect. The other speeds that are common to try are 57600, 19200, 9600.
7. Change the COM Port to the number that you found in step number 2. If you found more that one option in step number 2, look at the HN-232 device and as you are testing the communication the amber light on the HN-232 device should come on (after you click Options, Communications). If you have the wrong comport the amber light on the HN-232 will not light.
8. If the amber light on the HN-232 device is always on, then the HN-232 device could be bad or the HN-210 Radio Antenna could be bad. If the amber light on the HN-232 device never come on, then it could be your comport is bad (or wrong comport selected) or the HN-232 device is bad or the HN-210 Radio Antenna could be bad.
