Hi,

What I am trying to ask and know, is if I may change an access 3 Dualac2 without move anything in the logic board (software version) i.e. driver/controller got fixed on the power section, my question is if the driver/controller will work considering it has the same software released version than the one installed in the truck, just made changes in the performance parameters; i.e. acceleration %, speed, etc. Parameters which can be adjusted by the handheld. I just wonder if it could be possible trying to make an analogy with telecom equipment, where if I install a board with a software version equal o below the one is currently installed in the rest of the boards it works and, there is just need to make a specific performance changes

Just asking...

Did you replace the access 3? It is a dual AC traction controller. If so, you must do a software download to the truck and then recalibrate it. No way around it.

I'm having trouble understanding. Are you asking if that ZAPI handset will work with an RC5500?
