IR/Serial Send_Commands (Cont.)
Command
PTOF
Set the time duration
between power pulses in
.10-second increments.
PTON
Set the time duration of the
power pulses in
.10-second increments
SET BAUD
Set the IR port's DATA mode
communication parameters.
SET IO LINK
Link an IR or Serial port to a
selected I/O channel for use
with the 'DE', 'POD', 'PON',
and 'POF' commands.

Description
This time increment is stored in permanent memory. This command also sets
the delay between pulses generated by the 'PON' or 'POF' send commands in
tenths of seconds. It also sets the delay required after a power ON command
before a new IR function can be generated. This gives the device time to power
up and get ready for future IR commands.
Syntax:
SEND_COMMAND <DEV>,"'PTOF',<time>"
Variable:
time = 0 - 255. Given in 1/10ths of a second. Default is 15 (1.5 seconds).
Example:
SEND_COMMAND IR_1,"'PTOF',15"
Sets the time between power pulses to 1.5 seconds for the IR_1 device.
This time increment is stored in permanent memory. This command also sets
the pulse length for each pulse generated by the 'PON' or 'POF' send
commands in tenths of seconds.
Syntax:
SEND_COMMAND <DEV>,"'PTON',<time>"
Variable:
time = 0 - 255. Given in 1/10ths of a second. Default is 5 (0.5 seconds).
Example:
SEND_COMMAND IR_1,"'PTON',15"
Sets the duration of the power pulse to 1.5 seconds for the IR_1 device.
Only valid if the port is in Data Mode (see SET MODE command).
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD
<baud>,<parity>,<data>,<stop>'"
Variables:
baud = baud rates are: 19200, 9600, 4800, 2400, and 1200.
parity = N (none), O (odd), E (even), M (mark), S (space).
data = 7 or 8 data bits.
stop = 1 and 2 stop bits.
Note: AMX does not recommend using a cable longer than 10 feet
(3.05 meters) for the IR Ports.
Example:
SEND_COMMAND IR_1,"'SET BAUD 9600,N,8,1'"
Sets the IR_1 port's communication parameters to 9600 baud, no parity, 8 data
bits, and 1 stop bit.
The I/O status is automatically reported on channel 255 on the IR port. The I/O
channel is used for power sensing (via a PCS or VSS). A channel of zero
disables the I/O link.
Syntax:
SEND_COMMAND <DEV>,"'SET IO LINK <I/O number>'"
Variable:
I/O number = 1 - 2. Setting the I/O channel to 0 disables the I/O link.
Example:
SEND_COMMAND IR_1,"'SET IO LINK 1'"
Sets the IR_1 port link to I/O channel 1. The IR port uses the specified I/O
input as power status for processing 'PON' and 'POF' commands.
