Ethernet to RS-232 Insertion
Figure 30 is an example of an Ethernet to RS-232 insertion, in which an Extron
controller provides control of an HD camera via the IN1806 and IN1808 Series 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 scaler 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
RS-232 protocol on the next page).

3. Connect the TP cable to the endpoint as usual.
4. Connect a serial cable from the endpoint to the device to be controlled.
Port number
For Ethernet to RS-232 insertion, the insertion port number must be stated from a specific
universal asynchronous receiver-transmitter
(
UART) start point. This number is entered as
the Telnet port number when you establish communication with the insertion port.
For the purposes of this discussion, consider the Ethernet insertion ports as serial (RS-232)
ports. The input insertion port number is the UART start point + 1. The output insertion port
number is the UART start point +3. With the default UART start point of 2000, the input and
output insertion ports are:
