The location, name, and pin numbers of these ports are listed on the inside of the module door. They are: • PRT1 - Used to interface the module with user devices. This port is a serial port that accomm odates RS-232/423, RS-422, and RS-485 communication modes. Port PRT1 is capable of operating full-duplex at 300, 600, 1200, 2400, 4800, 9600, and 19200 Kbps. The default settings are 1200 Kbps, RS-232/423 communications. • PRT2 - Used to interface the module with user devices or a modem using DF1 protocol. This port is a serial port that accommodates RS-232/423, RS-422, and RS-485 communication modes. Port PRT2 is capable of operating full-duplex at 300, 600, 1200, 2400, 4800, 9600, and 19200 Kbps. • DH485 - Used to interface the module with the DH485 network. This port is not isolated and cannot directly drive the DH485 network. You must use a 1747-AIC link coupler to link port DH485 with the DH485 network.
