It looks like there are three different main controls that have been used with this particular model. There is a 5 pin connector on the opposite side of the control from the two wire connection that is either going to be labeled CON7, CON201, or CON202. If the connection is CON7, you should not have to use the software rewriter. If it is CON201 or CON202, the software rewriter would need to be used.
Thanks my board does have a con203 says monitoring only I also have two PCB one lower and upper the compressor comes off the top PCB both of which have the monitoring only 5 pin jack I want to make sure I do not need to update the Software on PCB or there is a replacement board with the update on it con203 on compressor PCB and con7 on Main PCB states top terminal 5v tx rx grd neither have the indication at top of TX or VCC nor indicate write only port
You should not need the software rewriter then.
