Rs-232 And Ir Signal Insertion; Ethernet To Rs-232 Insertion - Extron electronics IN1804 Series User Manual

RS-232 and IR Signal Insertion

The twisted pair input and output ports allow you to insert RS-232 and IR control signals
onto the same cable that carries video and audio to extend them to the Over TP port on a
connected endpoint (see figure 29 below and
can be inserted two ways:
•
•

Ethernet to RS-232 Insertion

Figure 29 is an example of an Ethernet to RS-232 insertion, in which an Extron controller
provides control of an HD camera via the IN1804 and a DTP HDMI 4K 230 transmitter.
Configure this type of insertion as follows:
1.
2.
Ethernet to RS-232 insertion (see "Ethernet to RS-232 Insertion") — A control signal
applied to the IN1804 LAN port can be routed to the RS-232 port of any connected
twisted pair device. The RS-232 insert inputs and outputs inserted via Ethernet can
support up to a 115K baud rate.
Captive screw insertion (see
only) A control signal applied to the IR Over TP captive screw port is tied directly to the
TP IN4 (DI model only) or to the TP Output 1A (DO model only).
You must physically connect a cable to the captive screw connector where a control
signal is to be inserted.
Connect a TP cable from the control system to the LAN port, directly or via a network.
If necessary to match the device to be controlled, configure the port RS-232 protocol
(baud rate, parity, data bits, and stop bits) (see
