4.3 RS-232C Connections
The SE3000 series field scanners use three control signals of Send(SD), Receive(RD), Signal ground (SG)
only. Since general personal computers are controlled by control signals, the computer does not function by
only connecting three signal cables without wiring processing inside the connectors. Wiring processing
depends upon the control signals being controlled by the personal computer. For details, read the
instruction manual for your personal computer.
The RS-232C cable length is restricted to be within 15m. The connection for NEC PC98 series
9-pin connector is in [Connection sample 1] and for the 25-pin connector is in [Connection sample 2].
