Delta DO 9704 Parity None Bit Stop bit Protocol Xon/Xoff, Command Type Reply, Type of terminal

ENGLISH

The transmission parameters with which the instrument is supplied are:

* Baud Rate	19200 Baud
* Parity	None
* N. bit	8
* Stop bit	1
* Protocol	Xon/Xoff

The data transmission speed may be changed by pressing the PROG key on the instrument to alter the set-up parameter P3. The possible Baud Rates are: 19200, 9600, 4800, 2400, 1200, 600, 300. The other transmission parameters are fixed.

All the messages reaching and leaving the instrument must be inserted in a “Communication fra- me” with the following structure:

Record-cr
where:
-Record-	constitutes the message
-cr-	Carriage Return (ASCII 0D)
HOST COMMANDS
COMMAND		TYPE	REPLY
AA		Type of terminal	MANOMETER – DL
AG		Firmware Version	Vx Rx
AH		Firmware Date	dd/mm/yy
A*			?
SA		Request	Input A
SB		Request	Input B
SC		Request	Input A-B
SI		Measurement	MANOMETER - DL
S*			NC

It is possible to unload data onto a computer using the Xon/Xoff protocol to control the data flow: The character Xoff (hex 13) on the serial line stops the data unloading in progress.

The character Xon (hex 11) reactivates the suspended data unloading in progress.

Dumping data from the memory

Press the PROG key twice until P1 appears on the display. Press the ENTER key.

The instrument continues to show P1 on the display and dumps the data from the instrument’s internal memory through the serial line.
