SECTION 1. GENERAL INFORMATION
1.1 INTRODUCTION
The RS16x16HB routing switcher is a device which accepts up to sixteen video
inputs and up to sixteen stereo audio inputs (that is, sixteen channels of left and right
audio), and connects any one of the input channels (buffered electrically) to one or
more of the sixteen outputs.
1.2 TECHNICAL DESCRIPTION
The RS16x16HB uses a single chip microprocessor with backup battery to
drive three monolithic latching crosspoint decoders, one for video and one for
each channel of audio. The video channel features a driver stage with a gain of two
to drive a 75 ohm coaxial line. The audio is set up for high impedance balanced
inputs and outputs with a gain of one, or optional 600 Ohm balanced inputs and
outputs at up to +l6db.
Crosspoint information is collected by the microprocessor from either the front
panel keypad or from the RS232 port on the rear panel, and distributed to the
crosspoint decoders. Audio and video may be routed together or separately. The
microprocessor program activates an automatic lamp test at powerup or when the
lamp test is called by front panel keypad or RS232 port. Each time a routing command
is sent, the entire current routing map can be reported on the RS232 port.
