2. Function
• 36-pin centronics interface (universal connector)
The system has the IEEE1284 interface (the Centronics interface) as a standard inter-
face to be used as a PC printer for future expansion.
• PCI bus (special connector)
It achieves network functions through network board (FPLAN) connection. This connec-
tor is not a cartridge-type interface but a dedicated connector (100 pin) for the original
board (FPLAN). Therefore, the market-available PCI bus port cannot be connected.
