  • Page 5: Features

    Model SW-VRS232 The local user can connect to the Sender unit. To add a remote user, an optional 2-gang wall plate would be needed. 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.

    Model SW-VRS232 2.2 Connecting the SW-VRS232-2R 1. If the optional 2-gang wall plate receiver (Model SW-VRS232-2R) will be used, make sure to plug the Catx cables to the correct connector on both ends. The unit is designed so that there is no damage if the cables are cross connected since the power distribution uses the same pins in the UTP cable, but if plugged incorrectly, the system will not work.

  • Page 8: Mounting The Sw-Vrs232-2S

    VGA –RS232 SWITCH AND EXTENDER Note about Touch-Screen LCD’s The system is designed to work the touch-screen LCD’s that use RS-232. USB touch-screens are not supported even if an adapter is used. When 2 stations are used (local and remote), you must ensure that both touch-screens are exactly the same make and model.

  • Page 12: Utp Cable Recommendations

    VGA –RS232 SWITCH AND EXTENDER 3.3 UTP Cable Recommendations GREEN GREEN BLUE BLUE Figure 3.2 UTP cables have 4 twisted pairs inside. The video transmission over UTP uses 3 individual pairs for each color (Red, Green, & Blue). As shown in figure 3.2 above, a characteristic of Category-5/5e/6 cable is that the pairs of wires are twisted at different rates.
