Signal Routing Example
The example in Figure 5 shows the VM-3DT connected to two TP-580R devices. An additional
TP-580R device can also be connected. The table below summarizes the types of
connections:

RS
-232 and IR signals are transparently routed between the VM-3DT source and two
acceptors.
Since RS-232 is designed for point-to-point communication, make sure that only
one RS
-232 signal is sent to a destination. However, although only one device may send
RS
-232 signals down a line, sending RS-232 signals to multiple devices is permissible.
You can send RS
-232 signals to an AV device via the transmitter or receivers that are
connected to the
VM-3DT. If you have set the DIP-switches to traverse to all outputs, any
command sent to a destination on one of the outputs will also pass to
the other output
destination
s, so you must verify that it will not have an unwanted effect on the other
destination
s.
In general
, we recommend that you set the DIP-switches to traverse to all outputs only when
all
destination devices are identical (same vendor and same product model) and avoid the
sending of concurrent responses
.
Routing the IR signal
In the example in Figure 5
, an IR emitter cable is connected from TP-580T to the Blu-ray
player and an IR sensor cable is connected to the TP-580R (2) receiver for receiving IR
remote signals. This setup lets you remotely control the Blu-ray player via the TP-580R (2)
receiver device, using the Blu-ray player IR remote control transmitter.
To route the IR signal you have to use
the Kramer external IR Receiver cable on one end
and the
Kramer IR emitter cable on the other end. Note that IR Emitter Extension Cables are
also
available, if required. For further details, see www.kramerav.com/product/VM-3DT.
Routing the RS-232 Signal
An RS-232 controller can be used to control the AV devices via the TP-580T RS-232 port by
sending RS-232 commands over HDBaseT lines to the remote connected AV devices.
In the example in Figure 5
, the Kramer RC-43SL control keypad is used to control AV devices
that are connected to both TP-580R (1) and TP-580R (2). RC-43SL is connected to the
TP-580T RS-232 port. The RS-232 ports on TP-580R (1) and TP-580R (2) are connected to a
projector and display, respectively. This type of setup enables you to control the projector and
display via the RC-43SL.
When RC-43SL sends a command to the projector on TP-580R (1), it bears no effect on the
display that is connected to TP-580R (2). If TP-580R (1) and TP-580R (2) were connected
each to identical projectors, both would respond to the sent RS-232 command.
