    • Connect PC running WireShark with iTach on an old Ethernet Hub (not a Switch)
    • Sniff the DHCP request and see what IP number was granted to the iTach.

  • Click Network and type in static IP in both IP Address and Gateway boxes
  • Type in 255.255.255.0 in Subnet Mask box, click Save

Installing OCIR on Windows

  • Unzip the OCIR package.
  • Move aa_eclipse_workspace to the root of C drive (C:\aa_eclipse_workspace)

Set the iTach in OCIR

  • Edit z_itach_set_1.py
  • In class OcirLink edit the list entry in self.device_data
  • Change the self.tag.device_ip data to the new IP number

Launch the example OCIR IR script

  • Open a command prompt and type:
cd C:\aa_eclipse_workspace\py\ocir_v1.05\ir_scripts
example_for_victor.py

Getting the list of available IR Commands

  • Open in an editor lists_of_key_names.txt
  • Use the table of command names specific to your remote

Adding more iTachs to OCIR script

  • Edit z_itach_set_1.py
  • In class OcirLink add a new list entry in self.device_data
  • Change the self.tag.device_ip data to the new IP numbers
  • Change the self.out_port1 / 2 / 3 to new names
    • Or you may use the same names to gang multiple outputs

Controlling more than one settop with the same iTach output
