2.1 RS-232C communication

2.1.1 Setup RS-232C communication
(1) Connect the MSD and the control device via an RS-232C cable.
(2) Set the RS-232C communication as follows:
・RS-232C communication: baud rate, data bit length, parity check, and stop bit
・Operation mode of RS-232C communication: "RECEIVER"
・RS-232C transmission between control devices: "OFF"
(3) For the control device, set the same values in the same way as RS-232C communication (baud rate,
data bit length, parity check, and stop bit) in step (2) above.
(4) Send a communication command from the control device to the MSD in order to check the control
status of the MSD.
