4. DESCRIPTION OF PARAMETERS
11
NOTE
1 An input/output device can also be selected using the setting screen. Usually, the setting
screen is used.
2 The specifications (such as the baud rate and the number of stop bits) of the input/output
devices to be connected must be set in the corresponding parameters for each interface
beforehand. (See Section 4.2.) I/O CHANNEL = 0 and I/O CHANNEL = 1 represent
input/output devices connected to RS–232C serial port 1. Separate parameters for the baud
rate, stop bits, and other specifications are provided for each channel.
3 The input/output unit interface may be referred to as the reader/punch interface.
RS–232C serial port 1 and RS–232C serial port 2 are also referred to as channel 1 and channel
2, respectively. The remote buffer interface is also referred to as channel 3.
