RS-232 Control and Pass-Through Using the VM-114H2C
, you can connect a PC (or other serial controller) directly to
the VM-114H2C to control the VM-114H2C.
The VM-114H2C also transparently passes bidirectional RS-232 signals over the
TP cable from the TP-573 transmitter to the TP-574 receiver. For example, a PC
connected to the RS-232 port on the TP-573 can control an RS-232-controllable
device (for example, a projection screen) connected to the TP-574.

Local IR Control and IR Pass-Through Using the VM-114H2C
The VM-114H2C provides an IR sensor and a 3.5mm mini jack for connecting a
remote IR emitter or sensor. When the VM-114H2C is connected to suitable
transmitters and receivers (for example, the TP-573 and TP-574), the
VM-114H2C can act as a pass-through for IR control signals, allowing remote
control of multiple devices using multiple IR remote controllers.
When there is no IR sensor or emitter connected to the IR remote 3.5mm mini
jack, all signals received by the IR sensor on the front panel are passed to the
transmitter and receiver bi-directionally over the TP cable allowing control of
remote devices.
