6.2 Connecting to a PC
You can connect to the transmitter/receiver system via an RS-232 connection
using, for example, a PC. Note that a null-modem adapter/connection is not
required.
To connect a PC via RS-232, connect the RS-232 9-pin D-sub rear panel port on
the transmitter/receiver system unit via a 9-wire straight cable (only pin 2 to pin 2,
pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub
port on your PC.
Figure 6 shows RS-232 bidirectional control of the projector that is connected to
TP-580Rxr, via a PC connected to the TP-580Txr:
