Axcess Programming
Send_Commands for the IR/Serial/Data Ports (Cont.)
CH
Generates IR digit
pulses to select a
television channel
number.
CP
Transmits IR code
pulses and clear all
commands in the
buffer.
CTOF
Sets the single IR
pulses off time
between channel
digits and IR
functions.
12
Channels 1-99 pulse as two digits. Channels 100 and greater, the one-hundredth digit
pulses as 127. If IR function 21 (enter) exists, it follows the IR digit pulses. CTON sets
the pulse length for each digit and CTOF sets the time between each digit or any other
pulse.
Syntax:
"'CH',<channel>"
Variables:
<channel> = 0 - 199
Example:
SEND_COMMAND IR_1,"'CH',18"
The controller performs the following:
• Transmits IR pulses for 1 (IR code 11) for the time set by CTON.
• Waits for the time set by CTOF.
• Transmits IR pulses for the IR code for 8 (IR code 18) for the time set by CTON.
• Waits for the time set by CTOF. If the IR code for ENTER (IR code 21) is programmed,
steps 5 and 6 are performed.
• Transmits IR pulses for ENTER (IR code 21) for the time set by CTON.
• Waits for the time set by CTOF.
This command pulses the actual IR code. Pulse time is set by the CTON and CTOF
commands.
Syntax:
"'CP',<channel>"
Variables:
<channel> = 0 - 252
Example:
SEND_COMMAND IR_1,"'CP',2"
Clears pending commands and pulses command number 2.
CTOF sets the time between digits or any other pulse and CTON sets the pulse length
for each digit. This is the time between digits, or pulses, that is associated with an SP
command.
Syntax:
"'CTOF',<time>"
Variables:
<time> = 0 - 255 in tenths of a second; Time is stored in permanent memory. System
default is 5 (.5 second).
Example:
SEND_COMMAND IR_1, "'CTOF',10"
Sets the channel's off-time pulse in tenths of a second. Default time is 5 (0.5 second).
Time is stored in non-volatile RAM.
