•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
This selector sets the time length from when the machine detects the PC powered off until it recognizes the detected state as
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
•Selectors 6 through 8:Extension of incoming calling signal (CI) frequency band specified by selectors 1 through 4 on WSW14
At the start of reception, if the machine detects the frequency of a CI signal specified by selectors 1 through 4 on WSW14, it starts the ringer sounding. However, the machine may fail to detect the CI signal normally due to noise superimposed at the time of reception. To prevent it, use selectors 6 through 8 on WSW36.
If the machine detects higher frequencies than the setting made here, it regards them as noise and interprets the detecting state as being normal, allowing the ringer to keep sounding according to the preset number of ringers (until it starts automatic reception of FAX data in the FAX mode or enters the TAD mode in the TEL mode).
