Interface between Fax machine and Host PC consists of three layer structure as detailed below,
each sub-system can be operated at the same time by adopting a Oki-MFPI protocol in both Fax
machine and Host PC.
Note: A simultaneous operation is not supported in OKIOFFICE 44, but the structure is
same as other machine (OKIFAX 5000 series).
a) Application layer:
Performs a function control of each sub-system at the Host PC and Fax machine.
b) Data-Link layer:
Performs a protocol control at the Host PC and Oki-MFPI (TIA IS650 Level 1 require-
ment).
(Packetize/Unpacketize, flow control, Transfers command/data between each sub-system)
c) Physical layer:
Has a bi-directional interface control circuit which conforms to IEEE1284.
Standard mode:
Compatible, Nibble
Oki special mode: MCE (Mode Change Express)
