Trouble Shooting communication problems:
To help pinpoint the communication problem, the user should confirm the following:
A) Data Cables: If you are using your own data cables, confirm the pin outs to the UDC-RA Pin outs as shown above.
B) Sync DCE communications link is working error free end to end.
C) Async DTE communications are set to match the UDC-RA units settings on both ends of the link.
D) If possible, direct connect the two Async DTE devices together using a crossover cable between the devices to confirm that the Async devices are indeed working.
E) Single sided operation using one PC, one UDC-RA and one DCE device:
Set the PC and UDC-RA data rate and character length to the same rates and character length, such as 19.2k and 8,N,1(10 bit data). Set the Sync DCE at 19.2k and put the DCE(modem) into
Local Loop back. Plug in the data cables. Now exit and restart Hyper Terminal. Single sided communications should now work. If the user can establish single sided communications on each side of the Sync communications link, in all probability there is a sync communications problem between the two sync devices.
