RS-232 Wiring
There are 3 different RS-232 connections on the SW-0501-HDBT that use 2 different connectors.
RS-232 1 - Control of the SW-0501-HDBT using a 4-pin phoenix connector.
RS-232 2 - Control of local devices using a 4-pin phoenix connector.
RS-232 - Control of devices in a remote location by sending control signals via HDBaseT using a 3-pin phoenix connector.
RS-232 Connection Guidelines
The following wiring diagrams show the pinouts for the switcher. While not shown, connect the TX (transmit) to RX (receive) pins at the
control system or PC side of the cable. Most control systems and computers are configured for Digital Terminal Equipment (DTE) where
pin 2 is RX and pin 3 is TX This can vary from device to device, refer to the documentation for the connected device for pin functionally
to ensure that the connect connections can be made.
Method 1 - Individual Ports for Switcher and Device Control
This is the preferred method for switcher, local, and remote device control when there are multiple ports available on the control system.
Use Method 2 - Shared Port for Switcher and Remote Device Control to control the switcher and remote devices via a single RS-232 port
on the control system.
