Hello all,
I haven't dabbled in DCC since I moved up to 7mm 6 or 7 years ago. Back in August I bought a Lenz LH100 set up and collected a couple of Zimo MX645 chips from Digitrains at Telford. I have finally got around to getting everything out of the box setting it up and wiring in one of the chips/speakers etc.
I have managed to set up the Lenz to english etc. and not getting any sort of response out of the unit movement wise. using the standard "to track" wiring I moved the leads to the programming track terminals and tried again.
I have managed to go through the programming menus to get to read the address of the chip (I had in mind that the default address was no 3 but since I wasn't getting any movement when attempting to get it to run on address 3 I looked to confirm the actual address) but all I get is Error 02 which according to the manual is that it doesn't find a chip.
Below is a photo of the wiring set up -
Red and black to the track
Orange and grey to the motor terminals
The two purple to the speaker
The Blue and grey from the opposite end of the chip to the keep alive
All as per the diagrams/notes that came with the chip.
Initially I had the wires soldered to a couple of strips of PCB but I have taken them out of the equation and I have even tried clipping the crocodile clips direct to a pair of wheels and the soldered joint between the wires coming from the wheels to the red/black wires to eliminate any dirty track/wheels from the equation
Despite having done quite a bit of DCC in the past which included a couple of the old Bachmann split chassis, it was so long ago that I class myself as a complete DCC novice and any help that you can offer will be greatly appreciated. It's also my first foray into sound/keep alives.
