Usually our posts are about the latest and greatest, but with thoughts turning to the new season, I thought I would give some advice on two of our older but very popular products; the AIT250 and AIT1000 Class B Transponders. Both of these two products are based on the same Transponder PCB, which can still be repaired/serviced although PCB failures are fairly rare and faults can usually be traced to antennas or external wiring.
If you are the proud owner of one of these units, then you can be confident that should you have any problems, we are here to help you sort them out. We have produced a fault finding guide that covers the most common installation problems and also explains how to use the proAIS software to diagnose and fix problems. Click here for a copy of the Class B Transponder Fault finding Guide which is applicable to both of these units but not the latest AIT2000.
If you have lost the manuals for either of these two products, please go to our Support website https://support.digitalyacht.co.uk/.
The proAIS software really is your best tool in checking and fault finding these older transponders. It is only available for Windows and can be downloaded here. We also recommend watching this video which provides a useful guide to using proAIS…
The latest firmware is also available V10.11.14.0, but we would only recommend installing this if you are experiencing interfacing or TX time out problems.
Finally the only known issue with either of these products is intermittent “Phantom” Silent Switch operation on the AIT1000. If you see the occasional flashing of the blue Silent LED or the yellow TX time out keeps coming on, then it is worth either switching the Silent Switch setting in proAIS to “Switch has no function” if you do not have a Silent Switch fitted or alternatively connect the Blue wire in the Power/Data cable to the Black wire. This fault is due to spurious electrical noise “spikes” in some installations triggering the Silent Mode and shorting these two wires together or turning off the Silent Switch function fixes the problem.
