1. Introduction
1.1 General
Thank you for purchasing the Black Box AC505A-2A, a 2x1 Compact
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
input #1 for connection to a local LCD.
The AC505A-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 detection). This unit can be
controlled either manually using the front panel switch, automatically
based on video 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.
