Note:
• Selectors 2 and 3 will become operative if selectors 1 and 2 of WSW46 are set to
"monitor" the PC power ON/OFF state.
• Selector 1: ECP mode
The ECP mode enhances the normal bidirectional communications between the machine
and the connected PC for higher transmission speed throgh the parallel interface.
• Selector 2: Recovery from Inactive PC Interface
If the machine recognizes via the STB signal line that the connected PC is powered off
throgh the parallel interface, it will turn the PC interface outputs Low to protect the PC from
hazards that could be caused by weak electric current accidentally flown from the machine.
This selector determines whether or not the machine should recover from the inactive PC
interface to normal interfacing state upon receipt of data from the PC.
• Selector 3: PC Power-off Recognition Time
This selector sets the time length from when the machine detects the PC powered off until
it recognizes the detected state as power-off.
If selector 2 is set to "0," it is recommended that selector 3 be set to "1"; otherwise, the
machine may mistakenly detect PC powered off.
• Selector 5: Escape from phase C
This selector determines whether or not the machine will escape from phase C when it
detects an RTC (Return to Control) in non-ECM mode or an RCP (Return to Control Partial
page) in ECM mode.
