[Program ROM DIMM]
There are two kinds of program ROM DIMM.
CRF : Flash ROM DIMM
TNY : P2ROM DIMM.
Flash ROM is rewritable.
P2ROM is not rewritable.(Parts number are also changed whenever the versions change.)
[NIC Card]
There are three kinds of NIC Cards.
Oki LAN 6200e+
Oki LAN 7300e
Oki LAN 8100e
Note: To use Oki LAN 8100e, software for the NIC must be downloaded to a CU main board.
Software for the NIC is downloaded to a CU main board (HMF/HME) before shipment
of a printer or a service board.
As software is deleted when forced initialization is performed to a Flash ROM,
redownloading of the software is required. Software is not downloaded to a TIG-2/
TIG-3 also a program ROM DIMM doesn't support the software. Accordingly, the Soft
NIC (Oki LAN 8100e) is not usable even if software for the NIC is downloaded to a
TIG-2/TIG-3 board.
