Here's the one I have been trying to get to work... To make things more confusing the listings for LT1 are below. Doesn't matter to much to compare them as they all have the same Mode 1 Message send... well some are 5 and leave out the trans? But most have six.

Been looking through a lot of ALDL.ds files and good know working TP ADX files. One thing I notice added to TP files in a Mode 1 Message send is extra code added? not just this EE.ADX it is in $OD.ADX and others?

ALDL.ds says: MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $00
- CHECKSUM

TP Mode 1 Message 0 send says "0xF4 0x57 0x01 0x00 0xB4" So what is the "0xB4" for?

ALDL.ds MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 1)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $01
- CHECKSUM


TP Mode 1 Message1 Send and it says "0xF4 0x57 0x01 0x01 0xB3" So what is the "0xB3" for?

Go to third and last Mode 1 Message 2 and it adds a "0xB2"

Also found in A223.ds Mode 1 Messages for transmit data there are Six. But only 3 are in the EE.adx... I'm wondering if this is why I only get some data? So if I add the other three I may get my data, but really don't know if I should add a 0xB1 on one 0xB0 on another, but then whaat to do for third? Guess if I knew why they were there I would know what to do?
