Model VS-2A
1.0 General
Thank you for purchasing the Hall Research Model VS-2A 2-Port VGA
Switch with Audio & Serial Control.
This unit provides a video along with audio output that can be switched
between two video and audio sources. The unit also has a loop-out for PC
#1 Input for connection to a local LCD.
The VS-2A unit provides all the A/V and control connections on the rear
panel; the front panel has a push-button switch with corresponding LED
indicator for the selection of video source. The front panel also features
mode selection buttons to allow the unit to operate automatically (based
on video sync detection). This unit can be controlled either manually
using the front panel switch, automatically based on video sync detection,
or remotely through an RS232 serial port.
The unit can be configured to operate in two different modes, which are
Auto and Manual modes. There is a priority selection that can be used to
set for none, Input #1 or Input #2. Switched output can be blanked and
un-blanked either from the front panel button or from the PC command
sending through the serial port.
The unit also has EEPROM (internal non-volatile flash memory) to store
the last operating mode when power is off.
