Each pin of digital output terminal
Pin 1: Ground (GND)
Pin 2: Ground (GND)
Pin 3:
----
External equipment condition signal input. Use it OPEN (Busy in)
Pin 4: RTS output
Directly connects to the CTS terminal of the personal computer at the
time of two-way communications by RS-232C.
Outputted at the voltage level of about } 10V.
Pin 5: External power input
Positive electrode of power when supplying power from outside. Pin 1 or
pin 2 is the ground. Use the power of 8 - 12 VDC, 100mA or more.
Pin 6: CTS input terminal
CTS input
Directly connects to the RTS terminal of the personal computer at the time
of two-way communications by RS-232C.
Pin 7: TxD output
Directly connects to the RxD terminal of the personal computer at the time
of two-way communications by RS-232C.
Outputted at the voltage level of about } 10V.
Pin 8: Measured value serial output
Use it OPEN.
Pin 9: RxD input
Directly connects to the TxD terminal of the personal computer at the time
of two-way communications by RS-232C.
Pin 10: Synchronous clock output
Use it OPEN.
Pin 11: External measuring request signal input
Use it OPEN.
Pin 12: Internal supply power output
Use it OPEN.
î@Pins 3,8,10,11,12 are necessary terminals when succeeding to use the external
output function of the former model CS-100. Use them OPEN in case to use the
RS-232C communication mode. (Refer to the instruction manual of the main body
version.)
