*1. The I/O refreshing method is automatically set according to the connected Communications Coupler Unit and CPU Unit.
*2. The maximum transmission distance for an SSI Input Unit depends on the baud rate due to the delay that can result from
the responsiveness of the connected encoder and cable impedance. The maximum transmission distance is only a guide-
line. Review the specifications for the cables and encoders in the system and evaluate the operation of the actual equip-
ment before use.
