Example 5

This example demonstrates how to send out an IR string from

the IPL T SFI244. The line below shows an HTML hyperlink

with an Extron IR command encoded into the URL.

The ? cmd=W1*1*15*0ir| is the syntax for the URL encoding

of an IR command that will be sent out of IR port #1. The “W”

and the “|” (pipe symbol) are used as the leading and trailing

delimiters for the instruction that tells the box which port

number, .eir ﬁle or function within the .eir ﬁle to send. The

command also allows the programmer to deﬁne whether the

IR should be sent once or continuously until stopped. The IR

Learner program determines which IR function, such as play, is

assigned to which number. See the IR Learner program for help

with this feature.
