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 A)
(c) OKI HSP interface (Option)
This interface (slot) is an OKI unique universal interface that provides the platform to connect various
boards (including those supplied by third venders) such as the LAN connection expansion board.
Any expansion boards compatible with this interface can be mounted on the Control board without
modifying the program at the printer side. The conceptual diagram of the OKI HSP interface is shown in
Fig. 2-2.
(For the electrical/physical characteristics of the OKI HSP interface, see the OKI HSP interface technical
manual. This manual will not be available to the general public.)
(8) RAM module
• Pin layout
• Basic specificaton
- Type: 72 pins SIIM (32 bits buss width)
- Access time: 60ns, 70ns, 80ns, 100ns
- Capacity: 1, 2, 4, 8, or 16MB (16 MB RAM will not be sold by Okidata)
