AstroTac Receiver ATAC3000 interface Problem
Posted: Tue Nov 24, 2020 9:06 am
Hi Group,
I've been working on interfacing an AstroTac Receiver to an ATAC 3000 comparator. for P25 Digital. Reading the Codeplug it shows the unit is a Quantar Satellite Receiver not an Astrotac Receiver. (curious) The problem is that it seems the unit thinks there is no wireline installed. Wireline is part of the PS module in the ATAC Rx. Looking at the Status panel screen it shows wireline off. When I try to validate the station it shows wireline not installed But it also says V.24 link installed. I've connected other Astrotac receivers to the ATAC with no problem. There is no interface V.24 cable issues as the same cable is used for each Rx. Same problem occurred with another AstroTac Rx but in that case I changed out the Power Supply board with another unit and it worked. Are there differences in PS/ WIreline cards? No changes to codeplug Quite confusing. Swapping the PS/Wireline and the V.24 link worked and the ATAC responded when the RX was active . So the questions are . Is there a setting on the Power supply / Wireline card that tells RSS whether there is wireline present? Is there a software setting to turn on the wireline ? Is there a Firmware issue here ?
Any Suggestions to enlighten will be appreciated
Thanks
Larry
