Hitachi EH-150 Series - Initial Setting

Chapter 6 Communication mode
6 - 78
Hi-Protocol
6.5.4 Initial setting
After power activated, EH-SIO enters idle status (waiting initial setting by CPU module). EH-SIO starts
Hi-Protocol mode operation by initial setting from CPU module.
During Hi-Protocol mode, EH-SIO continues this mode even if CPU module is in stop mode. To change the
communication mode of EH-SIO, power rebooting or reset operation of EH-SIO is requested.
« Note »
EH-SIO will not receive any command from CPU module except initial setting command before initial setting is
completed. At that time, EH-SIO will not receive any command from connected external device.
