General Overview of RS232 Control of the CK 2.2 Keypad
Controlling the CK 2.2 via RS232 from the B&K CT Series
Receivers or an Automated System
Overview
The B&K CT Series Receiver has the ability to send RS232 messages to the CK 2.2
keypad when triggered by a B&K IR command, video sense, audio sense or voltage
sense. These messages can instruct any or all keypads to jump to a specific device and
page (this is what is done to provide keypad status of a zone input change) or in more
advanced systems, to instruct the keypad to jump to a specific device, page and button
(thus triggering the macro or infrared command stored in that button).
Any automation system with the ability to send RS-232 text strings can successfully
control a B & K CK 2.2 keypad as well, offering complete local control of IR devices by
running a single CAT 5 cable to a locally installed CK 2.2.
Examples of RS232 Macros
Example 1 - Turn off ALL TV’s everywhere when leaving the House
The CT Series Receiver has hundreds of B&K unique IR codes available for use as
RS232 macro triggers. You simply assign one of them to trigger an ALL OFF RS232
Macro using BKc Suite’s RS232 Macro Editor then teach that “trigger” IR command into
the TVOFF button on the kitchen keypad next to the garage door.
Then you program each of the keypads controlling a local TV by placing a different
discrete Off command for each unique local television in exactly the same button
location (Device, Page and Button address) on every keypad. That way, you don’t have
to create six different RS232 macros. Instead, you use one macro with the global ID #
FF (255) which will command all of the keypads in the system.
In use, when the CT Series Receiver sees this unique IR code from the Kitchen keypad,
it will issue the RS232 macro to all of the other keypads. Each room’s keypad will then
issue a discrete Off command to each of the local TV’s. With some automation systems,
you could accomplish the same thing by assigning the RS232 message to a touch
screen icon.
