Hi all is there a way to convert a Rs232 command to IR?

This is from the remote guide of the JVC HD 350:

"To send an Infrared command to the projector, the required format is 73, followed by the
ASCII value in hex of the command required. The ASCII values for all of the Remote Control
Emulation Commands are shown in right hand column of the Remote Control Emulation
Command tables on pages 4 and 5.
As an example, to send the Power On command, we would send: 73 05"


I was told the Pronto can convert them is that true? and how?

This is new to me this conversion,  ive never done this before.
