Connection and Setup of the AD2079 2-3
Keyboard Setup
Setting up the AD2079 keyboard involves selection of the appropriate communications protocol,
and setting the keyboard's baud rate, LED brightness, speaker volume, and PTZ motion control.
Communications Protocols
The AD2079 keyboard can operate with one of three communications protocols:
RS-232 (factory default setting)
RS-422
RS-485
Select the appropriate protocol by setting an eight position DIP switch, labeled
COMMUNICATIONS SWITCH, located on the bottom of the keyboard. The factory default
setting is for RS-232 communications. To access the DIP switch, remove the bottom plate of the
keyboard, and locate the switch next to the eight pin RJ-45 port. Unplug the wall transformer.
Set the DIP switches according to the following table:
Port Use
1 2 3 4 5 6 7 8
RS-232 1 1
000000
RS-422
00
11
0000
RS-485

After completing the DIP switch settings,
re-attach the keyboard’s bottom plate and
plug in the transformer.
