*1 To use at 460.8Kbps or 921.6Kbps, set the XPort as high performance mode. Please refer to the User's manual.
*2 Half duplex of RS-485 requires to send data while there is not data from other devices. SI-65 detects a state of no data transmission of other devices for the timer period specified by the switch, and notifies CP2 of the XPort of the state.
*3 Half duplex of RS-485 need to make the RS-485 driver active only sending data. The RS-485 driver IC will be instantly activated at the head of data, and automatically deactivated with the lapse of the timer period specified by the switch once the end of the data is reached.
*4 Supplied either from.
*5 When using the attached AC adapter (AC100V).
*6 Operation temperature will be -10 to 40 degree Celsius when DC power voltage from Dsub connecter is more than 10V.
