When the contact closure control is connected to the DA1917SX, an “open” position will select Input 1 and a “closed” position will select Input 2. Although the DA1917SX is designed primarily to handle VGA-type (RGBHV) signals, it can also be used to pass Composite Video, S-Video, and Component Video signals through its Red, Green, and Blue channels. This may require the use of adapter cables to convert from a 15-pin HD connector to BNC connectors. The DA1917SX is perfect for applications that require one local monitor to share two computers. It is also ideal for use in applications that make use of wall or floor plates for auto switching. The DA1917SX may be mounted to furniture or other suitable surfaces using optional hardware.

Table 3. DA1917SX Electrical DESCRIPTION OF DA1917SX 4 4 SWITCHERS 4.1 AUTO-SWITCH MODE The DA1917SX automatically selects the active source by sensing the incoming sync or video signals. If you are switching a RGsB signal, the DA1917SX will automatically sense the sync from the Green channel. When two active sources are present, the DA1917SX selects Input 2 as the default. 4.2 MANUAL SWITCH MODE The DA1916SX can be controlled manually by connecting a contact closure control switch to the Channel Select port of the DA1917SX. This port uses a 2.5mm mini-coaxial remote control jack and is located next to the Input 2. (Note that the connector used for the Channel Select port is the same as the power connector used for the unit. (No damage will occur if the power is accidentally connected to the Channel Select port). Altinex offers a remote control switch with a 12 feet cable (Part # RC5203CC) which performs this control function. The DA1917SX can also be controlled using AV control systems. When a remote control switch is connected to the Channel Select port, Input 1 will be selected if the Channel Select Contact is “open” and Input 2 if the Channel Select Contact is “closed”. It does not matter whether there is one active signal or two active signals – the switching will be identical. The LED lights next to each of the inputs will indicate which input is selected. Both Outputs of the DA1917SX are fully buffered and are capable of driving a signal over 200 feet of high quality coaxial cable. APPLICATION DIAGRAM 5 5 INSTALLING YOUR SWITCHER 6 INSTALLING YOUR SWITCHER 6 SWITCHERS Step 1. Make sure that the proper power adapter is used. The Altinex power adapter is supplied with the unit. Step 2. Connect the power adapter to the power port. Observe the power indicator light turning red and the input lights turning red. Step 3. Remove the anti-static connector covers and connect the cables from the computer video card or from the video output of other sources, to Input 1 or Input 2 of the DA1917SX. Step 4. Connect the cables from the output port of the DA1917SX to the large screen monitor or data projector. Step 5. If remote control switch is used, connect the RC5203CC to the Channel Select port. Step 6. If control system is used to control the DA1917SX, connect Channel Select port of the DA1917SX to the relays port of a control system. Step 7. Verify that the picture quality on the display is good. If you are not receiving a signal, make sure that the display is compatible with the resolution of the computer graphics card. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258-4623 or 1-714-990-2300 for international calls. OPERATION 7 The settings of the DA1917SX Switcher can be adjusted using auto-switch mode and manual switch mode as described in Section no. 4. There are no other adjustments necessary to operate the unit. The DA1917SX will operate successfully as long as cables are attached properly and other specificat...
