Ingenico iPP320, iPP350, iSC220, iSC250, or iSC480 cable connects your terminal via Ingenico hdmi connector on one end, and a RS232 DB9 connecter on the other end, with external power connector port. Cable has a length of 5 meters.
NOTE: Not suitable for IBM registers.
Our setup is a little weird and I needed a longer cable to make it worked. Been using this cable for a month now with now issues at all.
