I have a Hand held and a laptop version of the HHT and works on 2 of the 3 elevators in the machine room but not the 3rd.
I need to do a floor height update on an EPOCH 1.
I checked and replace the ribbon cable harness for the comm port but still nothing
Any ideas

Figured I post this here since it's somewhat relevant. I have a customer with a similar issue. HHT (Termiflex HT/1000) is not communicating with the EPOCH 1 Controller.
RJ116C Internal Connector | DB25 Connector
Pin1 (WHT) GND | Pin 7
Pin2 (BRN) TX | Pin 2
Pin3 (YEL) RX | Pin 3
Pin4 (GRN) RTS | Pin 4
Pin5 (RED) CTS | Pin 5
Pin6 (BLK) PWR | Pin 25
DB25:Pin6 (DSR) Tied to DB25:Pin20 (DTR)
Pin (PCB via) 65 to Pin (PCB via) 66 is tied on the SBC board.
Is there anything we are missing on this cable Pinout?
