USING THE S170i

SYSTEM INTEGRATION (RS-232)

The S170i’s RS-232 port offers extensive integration to sophisticated media-system and home-automation control, and permits full control of all of the S170i’s features. Using this port, the S170i can be connected to any other device with an RS-232 port, such as a personal computer or a home automation system. Any command or function that can be issued from the front panel or the HTR 2 remote controller can be performed via the RS-232 port, and information feedback of the S170i’s current settings, including MultiSource status, is transmitted from the preamp’s RS-232 port to the connected PC or device. The S170i’s MultiSource features are thus also fully controllable via RS-232 command.

TECHNICAL DETAILS

The RS-232 port uses the following standard pin-out arrangement:

DB-9 Pin #	Function
2	Transmit Data
3	Receive Data
5	Signal Ground

NOTE THAT:

•A standard, “straight-through” serial cable (not a null modem cable) must be employed to connect the S170i to a PC or other serial device.

•S170i serial communications must employ 8 data bits, no parity, and 1 stop bit; the data rate is 12000 bps (baud). (Some serial devices are unable to communicate at 12000 bps; a bit-rate converter to convert S170i communications to 9600 bps is available as a separate accessory; contact your installing NAD audio specialist.

A Windows 95/98/ME-compatible application for serial control of the S170i from a PC, as well as complete details of the S170i’s serial-communications protocols, are available for download from the NAD website:
