I/O port selection (selector switch) Set this to RS-232C.

Unit #, parity, and transfer code (DIP SW1-1 to SW1-7)

Set SW1-1 to SW1-7 to OFF (0).

Synchronization (selector switch) Set this to Internal.

Communications speed (DIP SW2-1 to SW2-4)

Set these switches to 0010 to select 19,200 bps.

Set these switches to 1010 to select 9,600 bps.(0: OFF 1: ON)

1-to-1/1-to-N selection (DIP SW2-6) Set SW2-6 to OFF (0) (1-to-N).

Instruction level (DIP SW2-7, SW2-8) Set these switches to ON (1). (Levels 1, 2, and 3 are enabled.)

CTS selection (selector switch) Set this always to 0 V (ON).

Unit #, parity, and transfer code (DIP SW1-1 to SW1-5)

Set SW1-1 to SW1-5 to OFF (0).

*Parity is fixed at Even Parity. Transfer code is fixed at ASCII 7 data bits and 2 stop bits.

Communications speed (DIP SW2-1 to SW2-4) Set these switches to 0010 to select 19200 bps. Set these switches to 1010 to select 9600 bps.

(0: OFF 1: ON)

1-to-1/1-to-N selection (DIP SW2-6) Set SW2-6 to OFF (0) (1-to-N).

Instruction level (DIP SW2-7, SW2-8) Set these switches to ON (1). (Levels 1, 2, and 3 are enabled.)

CTS selection (DIP SW3-1 and SW3-2)

Set SW3-1 to ON (1), and SW3-2 to OFF (0). (Set this always to 0V.)

Synchronization (DIP SW3-3 to SW3-6)

Set SW3-3, SW3-5, and SW3-6 to ON (1), and SW3-4 to OFF (0). (Set these to Internal.)
