Direct connection
To connect C3-400 Pro with a PC directly, connect both devices with a straight network
cable. As the C3-400 Prosupports auto MDI/MDIX, it is not necessary to use a crossover
type cable.

Important Notes:
1. RS485 communication wires should be a shielded twisted
pair cable. RS485 communication wires should be connected
in a bus cascade topology instead of a star topology, to
achieve a better shielding eect by reducing signal reection
during communications.
2. A single RS485 bus can connect up to 63 access control
panels, but preferably 32 is recommended maximum.
3. To eliminate signal attenuation in communication cables and
suppress interference, if the bus is longer than 200 meters,
set the number 8 DIP switch to the ON position. This is
equivalent to a parallel connection of one 120ohm resistance
between the 485+ and 485- lines.

Restore factory setting
1. If you forget the IP address of the C3 panel or the device does not work normally,
you can use the number 7 DIP switch to restore C3-400 Pro to factory default set-
tings. The parameters which gets reset are device IP address,
communication password, gateway, and subnet mask.
2. The switch is OFF by default. When it is moved up and down for three times
within 10 seconds and nally returned to OFF position, the factory settings will be
restored after the access control panel is restarted.
OFF OFF

To reset factory settings
Turn #7 switch ON and OFF
Repeat process 3 times
