Operation of this equipment in a residential area is likely to 2 SWITCHERS cause harmful interference in which case the user will be required to correct the interference at his own expense. • Any changes or modifications to the unit not expressly approved by Altinex, Inc. could void the user’s authority to operate the equipment. ABOUT YOUR SWITCHER 2 The DA1916SX is a 2-in, 1-out VGA (VGA/SVGA/XGA) Auto Switcher with manual remote capability through the use of a contact closure. The DA1916SX automatically switches to the active input source by sensing an incoming signal. If two input signals are active simultaneously, the DA1916SX will default to Input 2. Please note that the DA1916SX may be custom modified at the factory upon request so that it will default to Input 1 instead of Input 2. The DA1916SX offers both a main output for the selected source and a loop output that always passes through Input 1, regardless of which input is selected. The main output is fully buffered and, if it is not used, it must be terminated with a 75 Ohms VGA termination plug (part # MS8000TP), which is supplied with the unit. The DA1916SX can be controlled manually by connecting the contact closure control to its 2.5mm mini-coaxial remote control jack. The DA1916SX is packaged with a small switch and a six foot cable (part # RC5203CC), which controls the DA1916SX or the contact closure may be made from a control system. When the contact closure control is connected to the DA1916SX, an open position will select Input 1 and a closed position will select Input 2. Although the DA1916SX is designed primarily to handle VGA-type (RGBHV) signals, it can also be used to pass RGBS and RGsB. It may also be used to pass composite video, s-video, and component video signals through red, green, and blue channels. This may require the use of adapter cables to convert a 15-pin HD connector to BNC connectors. The DA1916SX is perfect for applications that use wall or floor plates for auto switching. It also works very well as a building block for classroom training systems in which the instructor’s signal is placed alongside a bus (via the loop output) to each of the student’s stations. The students own computer is connected to Input 2. The DA1916SX may be mounted to furniture or other suitable surfaces using optional hardware.

Table 3. DA1916SX Electrical DESCRIPTION OF DA1916SX 4 4 SWITCHERS 4.1 AUTO-SWITCH MODE The DA1916SX automatically selects the active source by sensing the incoming sync or video signals. When switching a RGsB signal, the DA1916SX will automatically sense the sync from the green channel. When two active sources are present, the DA1916SX 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 DA1916SX. This port uses a 2.5mm mini-coaxial remote control jack and is located next to Input 2. (Note: the connector used for the channel select port is the same as the power connector used for the unit. Damage will not occur if the power is accidentally connected to the channel select port. Altinex offers a remote control switch with a 12 foot cable (Part # RC5203CC) which will control the DA1916SX. The DA1916SX 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. Input 2 will be selected if the channel select contact is closed. The switching will be identical whether there is one or two active signals. The LED lights located next to the inputs will indicate which input is selected. The DA1916SX’...
