Technical Specification of the Halcro RS232 Port
· 9600bps
· 8 data bits, one stop bit, no parity
· binary transmission, no flow control
NOTE!
Not necessarily all commands and sub-commands work with all software releases. Users of the
older software releases should consult older revisions of the manual. New commands are added
continuously to this document as they are added to the software.

Input commands
Single Byte User Commands
The following commands are all single bytes sent to the RS-232 port. They create various output
data depending on the system status, so a comprehensive output data feedback cannot be given.
The reception of these commands must be first activated by sending RS_ENABLE_CONTROL
command before each command. See Special Commands section below.
For further information of the commands, refer to SSP Manual section User Interface Commands.

Enables the reception of most RS232
commands
Reception is deactivated after every received
command, so this command must be sent again
before the next command.
RS_DISABLE_CONTROL
1 225 Disables the reception of RS232 commands.
This command is seldom need as control is usually
disabled after every RS command.
RS_QUERY_SYSTEM_STATUS
1 227 Request for various status information. No
need to enable RS control. This command sends out
the information described below.
