Setting instruction:
1. The switch is for bypassing RS232 signal or for firmware updating.
2. According to the silk prints nearby (“Program” for firmware update,
“Normal” for RS232 transmission), change the switcher positions to set
RS232 port’s function.
Update instruction:
① The user should receive a Firmware burn package, containing all software
needed for burning and updating the Firmware on the EEPROM.
② Connect an RS232 cable from RS232 port of unit to PC.
③ Power the unit.
④ Extract the zipped file from the burn package to a directory (e.g.
C:\dir_name).
⑤ Browse to the directory (e.g. C:\dir_name\) and double click the batch file
Update Source. bat (for TX) or Update Sink. bat (for RX).
⑥ A short description of the link created between the PC and the board
appears on the screen, followed by the burn progress percentage report.
⑦ A second stage of verifying the content of the EEPROM follows, also with
a progress percentage report.
