The Hall Research Dual PC Video & RS-232 Switch w/ remote user option is designed to allow one or two users to access one PC’s Serial RS-232 Port and VGA video signal.
A typical example would be connecting a touch-screen LCD to the unit and then be able to switch the touch-screen LCD between 2 PC’s. The local user can connect to the Sender Unit (Model SW-VRS232-2S). To add a remote user an optional 2-gang wallplate would be needed (Model SW-VRS232-2R).
The optional wall plate connects to the local unit via 2 CATx cables. No power supply is required for the wall plate.
One CATx cable is used to extend the Video and the other is used to extend bi-directional RS-232. The user at the Local Station can switch between the 2 PC’s by simply pushing a button on the unit’s front panel. LED indicators provide feedback as to which PC input is selected. The Remote station controls the same PC as the local (both displays show the same image).
Any RS-232 output from the PC is sent to both Stations, and RS-232 the data from each station are automatically multiplexed as a first-come-first-serve basis. This means that, for example, if the local station is sending RS-232 data to the selected PC, the RS-232 data from the remote station is ignored until the local station stops transmitting data for about a second. In this way collision of Rx data is prevented. If control of the input selection is needed at the remote station, an optional push button switch cord can be utilized (Model PB-SW). This push button plugs into the receiver wall plate and can sit by the remote LCD. It has a momentary button with built-in LED. Every time the switch is pressed the input selection is toggled between PC 1 and PC 2.
The LED on the remote push-button cord blinks once when PC 1 is selected, and twice when PC 2 is selected. The push button is only available in a 6 ft length, but can be easily extended since is uses a standard 3.5mm mini-stereo type of plug. The optional 2-gang wallplate (Model SW-VRS232-2R) can be located up to 500 ft. away from the local unit.
