1) Connection Cable
・For connecting external devices to the PC, use the RS-485
・Pin No. 1 and 2 as well as pin No. 3 and 4 are provided with the same functions to be used for by wiring.
・It is required to attach a terminating resistor to a device connected at the end of the transmission line.
Short-circuit connector pin No. 6 and 9. Then, terminating resistor (120 ohm) attached state is obtained.
・Set the converter switch of the RS-485
