The polling character set is c
This parameter is a string that specifies a character or set of characters to be treated as
polling characters. The unit will respond to any of these characters using ACK. This
parameter should normally be left blank.
Enable Message Numbering
When this check box is ticked the unit will override the message numbering of the local
equipment and substitute its own message numbering in the APACS 30 data. This is useful
when the locally connected equipment does not automatically increment the APACS 30
message number.
Disable Direct Mode
Enabling this setting will prevent the unit from automatically using Direct Mode (see below)
when it receives an APACS 30 packet without any call set-up.
Boot to Direct Mode
Direct mode is a mode of operation whereby the unit automatically routes APACS 30
packets to their destination without the terminal having to perform any call control. If this
parameter is set to “Yes”, then the next time the unit is rebooted it will operate in direct
mode. For Direct Mode to work you must set up the appropriate addressing information
(e.g. Transport protocol, NUA, NUI, IP address etc). If this parameter is not enabled the unit
will still try to use direct mode if it detects that it is required (due to the absence of call
control information). This parameter can be used in certain cases where for some reason
the unit cannot automatically determine whether or not to use direct mode.
Use response code n in "unable to authorise" message
This parameter only applies when the unit is operating in direct mode. In cases where
the unit is unable to send the APACS 30 packet to the remote host, it replies to the
terminal with an “unable to authorise” message. By default, this message contains a
response code 05 which means declined. Entering a number for this parameter causes
the unit to use that number in place of the default response code. A value of zero for this
parameter prevents the unit from replying.
Clearing time n milliseconds
This parameter defines the clearing time in milliseconds that an X.25 call will be left
“open” after receiving a response from the host. Each response from the host resets this
timer.
Delay transmitting the APACS 30 string for x milliseconds after connecting to X.25
host
Setting this parameter will cause the unit to pause for the specified number of milliseconds
in between successfully connecting to the remote X.25 host and transmitting the APACS 30
string.
Retransmit APACS 30 string if error detected
Ticking this check box will cause the unit to retransmit the APACS 30 string to the terminal
if an error is detected. (e.g. no ACK received from terminal)
STX/ETX removal
Enabling “Del STX&ETX” will cause the unit to strip off the STX and ETX characters that
normally surround the APACS 30 string before sending it to the host. Enabling “Del STX
only” will cause it to strip of the STX character only.
