The external disk drive port is an NEC proprietary interface between the UltraLite and
the optional external
disk drive and parallel port adapter. These devices provide a
standard PC parallel port.
The AC Adapter plug is designed to work only with the NEC AC Adapter provided with
the UltraLite.
The RJ11 port marked "LINE" is connected to the telephone network, using the NEC
modem cable included with the UltraLite. The port marked "TEL" is used to attach a
telephone unit for convenience while communicating.
The RS-232C serial port is an NEC proprietary connector that works in conjunction with
the NEC cables to provide either a serial port compatible with those found in PC/XT
compatible computers or the IBM PS/2, or a null modem connection to a PC/XT or PS/2.
Cables provided with the UltraLite:
@ 9-pin DIN to DB25 (Straight) Serial Cable
@ Null Modem Adapter (25-pin to 25-pin or 25-pin to 9-pin)
