6.2 Precautions
(1) For the ERROR LED output, 330
Ω
is included in the circuit of the main body so that a current value will
be approximately 10mA. Use the LED whose forward voltage is approximately 2V. If the current value
exceeds 10mA in operation, the control board of the main body may go out of order or be broken.
(2) Connect all grounding conductors.
(3) The serial interface is equipped with a RS-232C driver and receiver. Be sure to use at the RS-232C
level.
(4) The RESET pin is pulled up at 3.3k
Ω
. Do not connect it if not used.
(5) Either serial or parallel interface is available. If not necessary, do not connect it.
(6) The accessory cable is approx. 300mm. Adjust the length as required. However, excessively extended
wiring may cause malfunctioning due to an effect of noise, etc.
(7) Only the pins for the serial interface should be connected to the 5V or higher power source. Otherwise,
the control board of the main body may be broken.
