AXC-232++ statements

The Axcess program of the AXC-232++ communicates with the AXC-EM as Device 0. Its device communicates with the RS232/422 Input/Output (I/O) of the AXC-232++ as Device 1. The following table lists AXC-232++ statements.

AXC-232++ Program Statements

Statement	Function
CREATE_BUFFER	Places strings that come from the AXC-EM into buffer. If no
0,buffer	CREATE_BUFFER 0 exists, the incoming strings from the AXC-EM are sent
	out the RS232 port.
CREATE_BUFFER	Places strings that come from the RS-232 port into buffer. If no
1,buffer	CREATE_BUFFER 1, exists, the incoming strings are sent to the AXC-EM.
CREATE_BUFFER	Places commands (i.e. SEND_COMMANDs) that come from the AXlink Master
2,buffer	into the buffer. Each command will be preceded by 2 characters: The first char-
	acter will always be an '*', the second character is the length of the command,
	the remaining n characters (as given in the second character) are the
	command itself).
CREATE_LEVEL	Places levels sent by the AXC-EM for level in variable.
0,level,variable
OFF[0,channel]	• Sends a RELEASE to the AXC-EM.
	• Sends message that channel is off.
OFF[1,channel]	Turns off a channel. This command has no external effect. It can be used as
	status.
ON[0,channel]	• Sends a PUSH to the AXC-EM.
	• Sends a message that channel is on.
ON[1,channel]	Turns on channel. This command has no external effect. It can be used as sta-
	tus.
SEND_COMMAND	Sends command to the AXC-EM. Provides support for commands like 'RDS'.
0,command
SEND_COMMAND	Sends command to the AXC-232++ as if the AXC-EM had sent it.
1,command
SEND_COMMAND	Sets the baud rate to 115.2k (DIP switch set to 300).
AXC_232,
'BAUDHIGH'
SEND_COMMAND	Sets the baud rate to 300 (DIP switch set to 300).
AXC_232, 'BAUDLOW'
SEND_COMMAND	Enables placement of characters in the buffer specified by
AXC_232, 'CB1ON'	CREATE_BUFFER 1.
SEND_COMMAND	Disables placement of characters in the buffer specified by
AXC_232, 'CB1OFF'	CREATE_BUFFER 1.
SEND_LEVEL	Sends variable as the value for level..
0,level,variable
SEND_STRING	Sends string to the AXC-EM.
0,string
SEND_STRING	Sends string out the RS-232 port.
1,string
