1. AS311 Overview

Hardware reset switch

When this switch is pressed, the AS311 will be reset. Use this switch when you have changed the switch settings.

Channel 1 and channel 2 serial ports

Used to connect the serial transmission line (RS-232C or RS-422). D-Sub 25-pin female connectors are provided on the AS311.

The pin assignment is as follows.

• The arrow on the above figure shows the signal direction.

• FG is connected with the T3’s frame ground internally. (both channels)

• DTR and RTS are ON while power is on.

• Data transmitting is available when CTS is ON. DSR has no effect for transmission.

• Pin 9 (5 Vdc) can be used to supply 5 Vdc power. (total max. 50 mA)
