Ethernet To Rs-232 Insertion - Extron electronics IN1804 Series User Manual

Unidirectional RS-232 insertion via SIS commands (see
•
Insertion via SIS Commands
the RS-232 port of any connected twisted pair device via SIS commands sent to the
IN1804. This method is unidirectional, meaning that the unit receives no response from
the device via the TP port.

Ethernet to RS-232 Insertion

Figure 31 is an example of an Ethernet to RS-232 insertion, in which an Extron controller
provides control of an HD camera via the IN1804 DI and a DTP HDMI 4K 230 transmitter.
Configure this type of insertion as follows:
1. Connect a TP cable from the control system to the LAN port, directly or via a network.
2. If necessary to match the device to be controlled, configure the port RS-232 protocol
(baud rate, parity, data bits, and stop bits) (see

3. Connect the TP cable to the endpoint as usual.
4. Connect a serial cable from the endpoint to the device to be controlled.
