B-500-EXT-330-RS-IP Installation and Users Manual
5.3.1.1 RS232 Operation Mode
The RS232 connection is used for performing Firmware updates in addition to sending RS232
signals. Switch 2 is used to set the RS232 Mode.
Note:
Switch 2 must be set to ON (Up) during normal RS232 Pass-Through operation.
5.3.1.2. Firmware Update Operation
As new source and display devices become available, it may be necessary to modify the firmware
in the B-500-EXT-330-RS-IP. To perform firmware updates, the dipswitches must be set to DTE
(Down) and Service (Down). Detailed instructions and updated firmware will be posted to www.
snapav.com as they are released.
5.4. Ethernet (RJ45) Connections
Bi-directional Ethernet signals are transmitted between the B-500-EXT-330-RS-IP Transmitter and
Receiver over the Cat5e/6 cable. The most common use is to send Ethernet signals for Networked
TVs or any device in the remote location that has an Ethernet connection. This connection is only
to be used for standard Ethernet signals and cannot be used for other communication formats.
Note:
This connection is for 10/100 BaseT Ethernet ONLY. DO NOT connect a cable from an
HDBaseT port.
