Altinex DA1914SX Application Diagram, Input And Outputs, Auto-Switch Mode, Manual Switch Mode

SWITCHERS

4.1 INPUT AND OUTPUTS

The DA1914SX uses four Female BNC connectors for each input and output. The DA1914SX can pass RGBS, RGsB, Component Video, S-Video, and Composite Video signals. Video signals must be passed through Red, Green, and/or Blue channels; Sync channel is not designed to pass video. C-Video must be passed through the Green channel.

4.2 AUTO-SWITCH MODE

The DA1914SX automatically selects the active source, by sensing the incoming sync. Sync sensing occurs on the Sync channel for RGBS signals and on the Green channel for RGsB or Composite signals. The sync source switch should be switched from SYNC to GREEN when using RGsB or Composite Video sources. The Composite source must be connected to the Green channel in order for the auto-switcher to work properly with composite video signals. When both signals are present, the switcher will default to INPUT 2.

4.3 MANUAL SWITCH MODE

The DA1914SX can be controlled manually by connecting a contact closure control switch to its 2.5mm mini-coaxial remote control jack. Altinex offers a remote control switch with a 6 foot cable, (Part # RC5203CC), which performs the manual switch function. The DA1914SX can also be controlled using contact closure relays on a control system.

When an active source is on INPUT 1, the manual switch will not affect the input, and will not switch to INPUT 2.

When an active source is on INPUT 2, the manual switch will act as an ON/OFF switch, forcing the switcher to INPUT 1 when the contact closure is in the CLOSED position.

When two active sources are present on INPUT 2 in the OPEN Switching Mode, the DA1914SX will select INPUT 1. If the contact closure is in the CLOSED position, and remains on INPUT 2, the contact closure will switch to the OPEN position. LED lights indicate the correct switching.
