XR (Extract a record) 4.8.14
Write
Syntax: EOT0000STXXRVal ETX BCC
Response
: STX0000XRRecBCC
Description
: This command is useful to save an active software file before pro-
cessing a new download.
Take care
: If Val = 1 -- Regulation is interupted , heater, evaporator and gas
flow are switched off making all software functions inaccessible.
Rules
: Val = 0: Stops the upload process.
Val = 1: Initilizes the upload process.
Val = 2: Autorizes the BVT3X00 to send the next record.
Val = 3: Ask the BVT3X00 to send the same record again.
The upload process is initialized by receiving «XR1» from the host computer. The
BVT3X00 sends the first Intel-hex record. The BVT3X00 waits then for «XR2» to
continue. This command autorizes the BVT3X00 to send the next record. This
handshake continues until the BVT3X00 sends the last record which is «00000
0 0 1 F F». The host computer must detect this record. Subsequently, BVT300
sends an "XR0" request to terminate the upload process and returns to normal
mode.
If BVT3X00 receives an «XR3» command, the previous record is sent again.
An «XR0» Command must be sent to terminate the upload sequence and return
to normal mode.
