6.1

Overview of the Debug-interface

The UNIGATE® IC features a Debug-interface, that allows a step-by-step processing of a script.
Normally this interface is only required for the development of a script.
6.2

Starting in the Debug-mode

When applying power to the UNIGATE® IC (power up) the firmware will output the binary
character 0 (0x00) after a self-test was carried out on this interface. If the IC receives an
acknowledgement via this interface within 500 ms, it is in the Debug-mode. The
acknowledgement is the ASCII-character O (0x4F).
With the start in the Debug-mode the further execution of script-commands will be put to a stop.
6.3

Communication parameter for the Debug-interface

The Debug-interface is always operating with 9600 baud, no parity, 8 data bit, 1 stop bit. It is not
possible to change this parameter in the Protocol Developer. Please make sure that these set-
tings match those of the PC-COM-interface and that the flow control (protocol) is set to "none"
there.
6.4

Possibilities with the Debug-interface

Usually the Protocol Developer is connected to the Debug-interface. With it a step-by-step pro-
cessing of a script, monitoring jumps and decisions and looking at memory areas is possible.
Moreover breakpoints can be set. It basically possesses all characteristics a software-develop-
ment tool is typically supposed to have. However, it is also possible to carry out a Scrip-update
via this interface.

Commands of the Debug-interface

The commands for the use of the Debug-interface are described in the instruction manual Proto-
col Developer.
