IR/Serial Ports Channels
IRRX Port Channels
IR/Serial SEND_COMMANDs
The following IR and IR/Serial Send_Commands generate control signals for external equipment. In these examples: <DEV> =
device.
IR / Serial Ports Channels
CHANNELS:
Description
00001 - 00229
IR commands.
00229 - 00253
May be used for system call feedback.
00254
Power Fail. (Used w/ 'PON' and 'POF' commands).
00255
Power status. (Shadows I/O Link channel status).
00256 - 65000
IR commands.
65000 - 65534
Future use.
IRRX Ports Channels
00001 - 00255
PUSH and RELEASE channels for the received IR code.
IR/Serial SEND_COMMANDs
Command
Description
CAROFF
Disable the IR carrier signal until a 'CARON' command is received.
Syntax:
SEND_COMMAND <DEV>,"'CAROFF'"
Example:
SEND_COMMAND IR_1,"'CAROFF'"
Stops transmitting IR carrier signals to the IR_1 port.
CARON
Enable the IR carrier signals (default).
Syntax:
SEND_COMMAND <DEV>,"'CARON'"
Example:
SEND_COMMAND IR_1,"'CARON'"
Starts transmitting IR carrier signals to the IR_1 port.
CH
Send IR pulses for the selected channel. All channels below 100 are transmitted as two digits.
• If the IR code for ENTER (function #21) is loaded, an Enter will follow the number.
• If the channel is greater than or equal to (>=) 100, then IR function 127 or 20 (whichever exists) is generated for the
one hundred digit.
• Uses 'CTON' and 'CTOF' times for pulse times.
Syntax:
SEND_COMMAND <DEV>,"'CH',<channel number>"
Variable:
channel number = 0 - 199.
Example:
SEND_COMMAND IR_1,"'CH',18"
This device performs the following:
• Transmits IR signals for 1 (IR code 11). The transmit time is set with the CTON command.
• Waits until the time set with the CTOF command elapses.
• Transmits IR signals for 8 (IR code 18).
• Waits for the time set with the CTOF command elapses. If the IR code for Enter (IR code 21) is programmed, the
Controller performs the following steps.
1) Transmits IR signals for Enter (IR code 21).
2) Waits for the time set with the CTOF command elapses.
CLEAR FAULT
Forces a reset back to normal status.
Syntax:
SEND_COMMAND <DEV>, "'CLEAR FAULT'"
Example:
SEND_COMMAND IR_1,"'CLEAR FAULT'"
