Data from T470 to projector Tx Mini-DIN Pin 3 (RXD)

Reply data from projector to

T470

Rx Mini-DIN Pin 5 (TXD)

After installation wiring of any projector to a T470, use a multimeter to check voltages of –9 on BOTH TX

and RX pins in any installation, as described in the troubleshooting part of this manual. A useful check that

you have actually connected to a valid RS232 input on the projector is to unplug the cable from the

controller and measure resistance down the cable to ground using a multimeter on the “K-Ohms” setting.

This should be 4k to 8 K-Ohms.
