There is new ATU firmware available for download, version 4.11. Whilst this is primarily intended for use with the latest keypads that have a green LED, I have now tested it with other keypads and find that it works perfectly with them as well. In particular, the older keypads also work correctly. I can confirm that it works with the following keypads:
Wired Keypads
Logilink Model: ID0008 (Red LED) (Originally supplied with the Mk-II controller in 2015)
Logilink Model: ID0184 (Blue LED) (Originally supplied with Stealth Loop in 2018)
Chinese Model: 12481 (Blue LED)
BaseTech Model: KEY1 (Distributed by Conrad Electronics SE, Klaus-Conrad Str, D-92240, Hirschau. www.conrad.com)
Wireless Keypads
eBay Chinese keypad model: WK-22K-ALG
Logilink Model: ID0120 (Distributed by Conrad Electronics, Order Number: 1545143 @ 12.99 Euro)

Many thanks for this Adrian. I need to reload the firmware and will now take the opportunity to try this … however I can’t find the firmware link or web page. Can you point me to it please (or email directly to neilbundle@yahoo.com) ? 73 Neil … G4LRV
