Some communication-related parameters require an inverter reset to take effect. Turn the Toshiba Media Converter off temporarily, and then turn it back on.
What to do if frequency instructions from the computer have no effect on my Toshiba Media Converter?
Ensure that the frequency setting mode selection parameter is set to 'computer'.
What to do if commands, including run and stop, from the computer have no effect on my Toshiba Media Converter?
Verify that the command mode selection parameter is set to 'computer'.
How to troubleshoot trip err5 and alarm t on Toshiba Media Converter?
Check the cable connection and the timer setting.
What to do if communication will not take place with my Toshiba Media Converter?
Please check the following: * Are both the computer and the inverter turned on? * Are all cables connected correctly and securely? * Are the same baud rate, parity, and bit length set for every unit on the network?
Why does my Toshiba Media Converter parameter return to its original setting after turning it off?
When using the TOSHIBA Inverter Protocol, ensure you use the W command to write data into the EEPROM. The P command only writes data into the RAM, which is cleared when the inverter is reset.
