1. connection of RS232 COMMUNICATION as shown in Fig. 2
2. Update/Modify serial number by DDCRUN (execution file) in
Factory mode.
- Connect DC adaptor (4.75 ~ 5.25Vdc) to Alignment box.
3 LED light should be at ON status at this moment.
- Connect 9 pins cable
- Connect 15pins D-SUB between Monitor and Alignment box.
Bring up Fig. 3
- Make a directory and copy "DDCRUN.EXE", "DDC.CFG", "DDC.HEX"
into folder as shown in Fig. 6.
- Press button1, the Red LED light should be at OFF status at this
moment.
Bring up Fig.5.
(If it is not at RS232 COMMUNICATION status, Mode selection key
can be used for exchange.
For example :
) RS232 COMMUNICATION, I2C COMMUNICATION
