The input power supply specifications vary with the model.
A 100 to 240-VAC model and a 24-VAC/VDC (no-polarity) mod-
el are available.
Connect to signal ground.
Receives data from SD of the master device.
Sends data to RD of the master device.
SD and RD for RS-485 (cold side)
Terminals 8 and 9 are connected internally when pin 9 of the
DIP switch is set to OFF.
SD and RD for RS-485 (hot side)
Terminals 11 and 12 are connected internally when pin 9 of the
DIP switch is set to OFF.
Connect to signal ground.
Receives RS-422 data and outputs it to the master side.
Converts data received via RS-232C from the master device to
RS-422 data and outputs the data.
Receives RS-422 data and outputs it to the master side.
Converts data received via RS-232C from the master device to
