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.

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
