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. The Remote unit can be located up to 500ft. away from the Sender Unit.
VGA –RS232 SWITCH AND EXTENDER 2. Installation 2.1 Connecting the SW-VRS232-2S Figure 2.1 1. For connection to a typical PC, use HD15 M/M cables for Video, and straightthrough DB9 M/F cables for RS-232. Connect all devices to the unit and then connect the Power supply to the device.

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.

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. This is because there is no software or special driver used with this setup and the PC is not aware that there are 2 touch-screens, therefore the calibration of both LCD’s need to be identical.
Model SW-VRS232 2. Drill pilot holes where indicated on the stencil, using a 1/16” bit. 3. Screw Selection: Be sure to use the appropriate kind of screw for the surface the unit is being mounted to. It is recommended to use a 1” long, #6 screw (shank = 0.138, or about 9/64”). 4. Remove the stencil and install screws, leaving 0.19” (about 3/16”) of the threads protruding (when measuring, do not include the screw head). CAUTION: Improper installation of mounting screws may result in damage to unit.

Model SW-VRS232 3. Configuration and Operation 3.1 Front Panel LED Indicators The SW-VRS232-2S has two sets of LED indicator lights. The Input Select LEDs indicate which input is currently selected. The Activity LEDs light when RS-232 data is being received, and indicate whether it is coming from the local station or the remote. 3.
VGA –RS232 SWITCH AND EXTENDER 3.3 UTP Cable Recommendations RED RED 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. Therefore, for a given length of Cat-5 cable the total length of a particular pair could be longer than others.
Model SW-VRS232 4. Troubleshooting Most common problems are caused by the following: • Using different models of Touch-Screen monitors • Crossed Cat5 cables. • Using a Cat5 cable that is too long, not straight through, or not terminated properly • Display device does not support the resolution that is being sent (in which case you should check operation without the extender first) 4.
