Hi, I am new to this forum and only started using it to get help with programming Zimo decoders which I'm not as familiar as ESU Loksound/lokpilot. Thanks a lot John for pointing out regarding the bridge wire on Dapol Class 68 board. I spent the whole weekend trying to activate aux 3 and 4 but to no avail until I read your advice. I used Zimo MX643D non sound decoder. I followed the instruction as described by Paul in his previous answer to a query about Zimo MX643P22 factory equipped decoder on Roco locomotive such as Class 460 Migros SBB. As suggested by NaN, to consider converting MX643D to MX643C. I am very pleased to inform you all that the Halo light works in both direction. So no need to cut the bridge wire. I may use John's method should I decide to use AUx 5 and 6 in future. Here are my steps: 1. CV8=3 to convert the amplified output to logic output. I think Dapol purposely provide an amplified output for (aux 3 and 4) to cater for ESU decoders which makes sense but I wish they could give information about this issue. What I don't know if this will also convert aux 5 and 6 to logic output on MX643D (not C) 2. CV61=97 which is an alternative function mapping without left shift. 3. Change CV37 to 48 to 0. I did not alter setting for CV33 to 36 to keep F1 and F2 keys as default for rear white headlight and rear tail red light. 4. CV129=1 to active aux 3 for front direction. 5. CV130=2 to activate aux4 for the reverse direction 6. CV430=3, CV432=3 and CV434=0. To use F3 key to activate the Halo lamp in forward direction. 7. CV436=4, CV438=0 and CV440=4. To use F4 key to activate the Halo lamp in reverse direction. That's it. I found Zimo manual is too comprehensive and complex. To some extent this also applies to ESU as well. I wished they would give basic instruction as described above for the novice like me. For the Zimo MX643P22, I wired to the base of the 21pin on the circuit board for aux 6 and 7 as well as common +ve to use for cablight and veissman coupler. Like Dapol, Jaegernddorfer also has amplified outputs for aux 3 (probably for aux 4) on its new Taurus locomotive. Again I presume they cater for ESU decoders. I had been struggling trying to activate the coach lightings for Jaegerndorfer Railjet coaches until I read NaN's suggestion. Thanks for your help guys. I hope this information will help other Zimo fans. Kind regards Nik Photo showing Class 68 with Halo light on
