11 AXB-232++ RS-232/422/485 Interface
Axcess program characteristics
The AXB-232++ is capable of running Axcess programs. It handles string processing, relieving
AXlink and the Master of the processing times.
AXB-232++ Send_Commands (Cont.)
RXOFF
AXB-232++ does not pass on
received characters to the
Master (default).
Syntax:
'RXOFF'
Example:
SEND_COMMAND AXB232,'RXOFF'
AXB-232++ does not pass on received characters to the master.
RXON
Enables AXB-232++ to send
incoming characters received
to the Master.
Syntax:
'RXON'
Example:
SEND_COMMAND AXB232,'RXON'
Enables AXB-232++ to send incoming characters received to the master.
The AXB-EM automatically sends this command to the AXB-232++ when it
executes a 'CREATE_BUFFER' program instruction.
TXCLR

ters waiting in the Transmit
buffer.
Syntax:

Example:
SEND_COMMAND AXB232,'XOFF'
Disables software handshaking.
XON
Enables software
handshaking.
Syntax:
'XON'
Example:
SEND_COMMAND AXB232,'XON'
Enables software handshaking.
ZAP!
Clears the Axcess program in
the AXB-232++.
Syntax:
'ZAP!'
Example:
SEND_COMMAND AXB232,'ZAP!'
Clears the Axcess program in the AXB-232++.
