There should not be an external repeater on a TAC32T, the FWIA has a repeater in it, probably what you are seeing on the print. There’s no reason what you did with the bottom access shouldn’t work. Since there is a repeater on the FWIA, you need to have 60 ohms on both sides of the repeater so I’m sure you do on the hoistway side but make sure you also do on the CPU side. A simplex should have all termination jumpers on the CPUA on and JP3 on the FWIA on. On a duplex, both controllers should have the termination jumpers on the CPUA on and JP3 on the FWIA off. 3 and 4 Car groups get the HC and RC jumpers on the CPUA removes on the intermediate cars and JP3 off. Make sure any CNA on that channel in the MR has its termination resistors removed. You can read resistance with power off on the 50 pin CPUA plug, HCH to HCL pins 31 to 32.
