WDG-5912 Programming - Getting Started
A programming interface is provided for the WDG-5912 through the RS-232 port. Programming
There are some important differences between the 4612 series and 5912 procedures.
Required equipment to program the WDG-5912:
1. RS-232 cable F-F Crossover type.
2. Terminal program (such as Hyperterminal) running VT-100 emulation at 9600 baud, 8, N, 1 with
Echo ON, no hardware handshaking.
3. RS-232 port on host computer running the terminal program.
Placing the Wedge into programming mode:
The WDG-5912 in normal operation will pass all printable ASCII characters input to the serial port to
the USB keyboard output. To utilize the RS-232 port for programming purposes it is necessary to
place the port / wedge into programming mode.
The wedge should be connected to the computer through the USB cable to provide power. The
RS-232 cable should be installed and the terminal program running.
Type the characters + + + into the terminal program.
The wedge should answer with “Command mode”.
Now the standard Cypress programing commands can be used i.e. \R \L etc. If you have not used
the Cypress programming interface, this manual will cover the details in the following pages.
After programming is complete, the wedge can be placed back into normal operation by pressing
the “Esc” (Escape) key.
Note: If you are using the same computer to program and host the USB interface, a condition can
occur during programming where a keepers will enter an infinite loop. This can happen when; the
terminal program is the active window, the wedge is in normal mode, and a key other than + is
pressed. The wedge will output the character to the terminal window where it will be fed back to the
wedge through the RS-232 port where it will then be output as a keystroke.
To terminate this condition, briefly unplug the RS-232 connection to the wedge.
