(a)Centronics bidirectional parallel interface
This is an interface conforming to
•Compatibility mode
Unidirectional communications from the host to the printer.
•Nibble mode
This mode transmits
•ECP mode
This mode provides the asynchronous bidirectional interface and transmits and receives
When the power is turned on, the compatibility mode is automatically selected. The change to another mode from the compatibility mode is made through negotiation. (When the BI DIRECTION is set to ENABLE in the menu, this change can be performed.) (For the electrical/physical characteristics of this interface, see APPENDIX B)
(b)RS232C serial interface
The following protocol is supported for the serial interface conforming to EIA RS232C.
•READY/BUSY (DTR HI or DTR LO)
•X-ON/X-OFF
•RBST X-ON
(For the electrical/ physical characteristics of the interface, see APPENDIX B)
(c)OKI HSP interface (Option)
This interface (slot) is an OKI unique universal interface that provides the platform to connect various of boards (including those supplied by third venders) such as the LAN connection expansion board and SCSI expansion board.
Any expansion boards compatible with this interface can be mounted on the Control board in the piggyback board from without modifying the program at the printer side. The conceptual diagram of the OKI HSP interface is shown in Figure
(For the electrical/physical characteristics of the OKI HSP interface, see the OKI HSP interface technical manual.)
