Advanced Programming Tips
Controlling the CK1.1 Via RS-232 From the B & K CT Receiver or an Automation System
RS--232 Overview
The B&K CT Receiver has the ability to send RS-232 messages to the CK1.1 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 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 CK1.1 keypad as
well, offering complete local control of IR devices by running a single CAT 5 cable to a locally installed CK1.1.
Examples of RS-232 Macros
Example 1 - Turn Off ALL TV’s Everywhere When Leaving the House
The CT Receiver has hundreds of B&K unique IR codes available for use as RS-232 macro triggers.You simply assign
one of them to trigger an ALL OFF RS-232 Macro using BKcSuites RS-232 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 RS-232 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 Receiver sees this unique IR code from the Kitchen keypad, it will issue the RS-232 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 RS-232 message to a touch screen
icon.
Example 2 - Turn Off Junior’s Stereo from any Keypad
If Junior’s room is equipped with a local stereo unconnected to the central system, it is still advantageous to program
and install a keypad to control that local system. Not only does Junior get the advantages of instant availability and
control when he walks into the room, his parents can turn off the system from any other keypad in the house.Thus,
if Junior falls asleep listening to music, Mom and Dad can turn it off without going to Junior’s room.
To program; simply teach the kid’s room Keypad to control the system, set the keypad ID# to a unique ID, then note
the ID# and the button address (Device, Page, Button) and program an RS-232 Macro with BKcSuite (assigning an
unused B&K code to trigger the macro). Program all of the other keypads with a JROFF button which contains the
trigger code.
In use, any keypad with a JROFF button sends the trigger code to the receiver.The CT Receiver sends an RS-232
message to Juniors keypad which turns off the local stereo(since the message is specifically addressed to that keypad,
no other keypad jumps anywhere). Of course, no serial macro can turn Junior off when he complains that someone
has turned his system off.
