SETUP FOR CUSTOM AND MULTI-ZONE INSTALLATIONS
REMOTE CONTROL CODES
The NAD C 425 has a remote control command receiver built in so it will
respond to NAD remote control commands, such as from most NAD
system remote controls. This will allow access to basic functions such as
preset up/down.
Particularly with Custom Install in mind, the NAD C 425 will respond to
other commands not usually found on NAD remote control handsets.
The table below indicates most commands the C 425 recognises.
The NAD C 425 uses the NEC format for IR transmission; customer code
is 877C, the corresponding hex codes are next to the IR command:

12V TRIGGER INPUT
NAD components equipped with 12V output triggers are fully
compatible with the C 425's 12V input trigger.
SYSTEM INTEGRATION (RS-232)
The C425's RS-232 port offers extensive integration to sophisticated
media-system and home-automation control, and permits full control of
all of the C425's features. Using this port, the C425 can be connected
HexCode
to any other device with an RS-232 port, such as a personal computer or
D2
a home automation system. Any command or function that can be
D1
issued from the front panel or the TNR 1 remote controller can be
D4
performed via the RS-232 port, and information feedback of the C425's
D3
current settings.

NOTES:
C7
Use a standard DB-9 male to DB-9 female RS-232 serial cable
F0
between your Windows®PC and the C425.
F1
Do not use a null-modem type of RS-232 cable.
37
Some Windows® PC's may not have RS-232 serial connector. In this
35
event, use a standard "off-the-shelf" RS-232 to USB adaptor to
F3
connect to your Windows® PC. Follow the instructions that come
F2
with the RS-232 to USB adaptor for setting up the adaptor. Your
26
custom installer or dealer can assist you in the proper setup and
82
configuration of the RS-232 interface.
81
Neither a DB-9 RS-232 serial cable nor a RS-232 to USB adaptor is
supplied with the C425.
