Page 18: Digital Operation Check
Set the POWER ON/OFF switch to OFF. When CO-OPT2-9/CO-OPT2-25/CO-OPT4-25 is used, the RS-232C/RS-485 controller may read incorrect characters when the POWER ON/OFF switch of the EPR series is operated. In this case, execute the readout command again or turn the POWER switch of the EPR series to ON and then restart the RS-232C/RS-485 controller to clear the read characters. -
