from defects in materials and workmanship and will perform substantially in accordance with
the accompanying written materials under normal use and service for a period of ten (10) years
from the date of shipment. Any implied warranties on hardware are limited to ten (10) years.
Some states/jurisdictions do not allow limitations on duration of an implied warranty, so the
above limitation may not apply to certain specific purchasers.
Software Warranty
Utah Scientific warrants that the software will perform substantially in accordance with the
accompanying written materials for a period of one (1) year from the date of shipment.
Customer Remedies
For the first one (1) year after purchase of the software and the first ten (10) years after the date

exclusive remedy shall be, at Utah Scientific’s option, either:
• Return of the price paid, or
• Repair or replacement of the software or hardware that does not meet the above warranties
and is returned to Utah Scientific under the returned materials authorization (RMA)
process with freight and forwarding charges paid.
After the initial warranty periods, purchaser’s exclusive remedy is the repair or replacement of

Scientific’s then-current price schedule. The above warranties are void if failure of the
software or hardware has resulted from an accident, abuse, or misapplication. Any replacement
software or hardware will be warranted for the remainder of the original warranty period or
thirty (30) days, whichever is longer.

viii BPS-2020
No other warranties. To the maximum extent permitted by applicable law, Utah Scientific and
its suppliers disclaim all other warranties, either express or implied, including, but not limited
to implied warranties of merchantability and fitness for a particular purpose, with regard to the

BPS-2020 (Bypass Switcher)
Receiving the System - Unpacking
The BPS-2020 consists of a 2 rack unit electronics frame and one or more
control panels. Power cards are provided for each device.
The 1 rack unit control panel can exist as the following versions; the BPS-8
(eight button control panel), the BPS-16 (multi-channel control panel), or the
BPS-16S (16 source control panel). See your sales order for details.

BPS-2020 (Bypass Switcher)
General Overview
How the System is Used
The BPS-2020 is intended to be downstream of all processing equipment
in a standard TV station environment. The Audio/Video output would
directly feed the transmission system of a station. The system can also be
used in any other AV switching application.
System Layout
The BPS-2020’s electronic components are housed in a 2RU rack mount
frame, while the control panel is contained in a remote 1 RU frame. The
electronics frame contains redundant power supplies.
The video section contains two slots; one for a crosspoint and another for
a video DA card, which provides looping input, or a video input card in 16
input systems.
The audio section contains two slots for 8x2 crosspoint cards. These
cards can exist as analog audio, standard digital audio, or deluxe digital
audio.
The BPS supports only balanced audio. A UDA-200 must be used to
convert to Unbalanced audio if the installation requires it.
Control Panel Variations
Stand Alone – 8 Standard Veetronix switches that represent one of the 8
inputs, or 16 switches for the 16 input systems.
Multichannel – 16 Veetronix switches in two banks of 8, with one bank
representing a channel select, and the other bank selecting one of the
eight inputs on that particular channel.
The control panel communicates with the electronics frame via RS-485.

Chapter 1 1-3
General Overview
Section1
Video Card Variations
There are two different video crosspoint cards. This card is the heart of the
system from a control standpoint, and orchestrates all system activities. The
121188-2 card is an 8 input crosspoint, while the 121188-1 is a 16 input
crosspoint.
The other video cards are the 8 circuit DA (121182-1), which can only be used
in conjunction with the 8 input crosspoint card, and the 121186-1 input card,
which contains the additional 8 input circuits for the 121188-1 16 input
system.
One other optional module, the 121169-1 Clean/Quiet submodule, can be
installed on either one of the crosspoint cards. This module provides
error-free switching of un-timed sources to provide the cleanest possible
video output.
Audio Card Options
There are 3 audio cards available. The analog audio card (121183-1) is a
stereo 8x1 device. Up to two can be installed for a dual stereo system. The
standard digital audio card (121184-1) is also an 8x1, dual stream device.
Two can be installed for a quad stream system.
The Deluxe Digital Audio card (121178-1) provides a V-Fade transition and
can be used as either a Quad 8x1 with two cards or as a dual 16x1.

System Installation
Rack Mounting
The 2 Rack Unit electronics frame should be installed near the master
control switcher in the main audio/video path of the system. The 1 Rack
Unit control panel should be installed in the Master Control room where it
is easily accessible to the operator.
Control Interconnections
Figure 1-1. Lower right chassis quadrant
This section of the BPS rear panel contains the control interconnections
for the system. The necessary connection between the control panel and
the electronics frame is a single CAT-5 cable between the panel port and
the RJ-45 connector on the back of the panel. Other control connections
include RS-232/422, tally and GPI’s.
See section 2 for pinout and other details of these control connectors.

System Installation

Multichannel Connections
Multi-channel BPS-2020 systems can operate as single units, as a networked
system, or both. To operate as a multi-channel system, a BPS-CP-16 is
required.
Figure 1-2. Basic Multi-Channel connection
The interconnect between the CP-16 and the bypass switchers is done with
standard CAT5 cable. The CP-16 is at one physical end of the bus and is
terminated internally. The cable then loops through the BPS-2020 chassis on
the two “BPS-NET” RJ-45 connectors. The open connector on the last
BPS-2020 should be terminated with USI part number 65324-04.
Note that each BPS-2020 must be addressed with a dipswitch on the video
crosspoint card.

Video Connections
Figure 1-3. 8-Input systems
Standard video ports include 8 inputs and 1 dual output connection. Optionally, a
DA card can be purchased that provides an active loop output for each input.
Figure 1-4. 16-Input systems
16-Input systems contain updated legends to describe the different BNC
functions. This system requires a 16x1 crosspoint card as well as an 8x input card
to be installed in the lower video slot.

Operation of the BPS-CP-16
Operation is very straight forward. The left bank of 8 buttons selects the
BPS-2020 chassis you wish to control. When a channel is selected, the right
bank of buttons will show its current status. A cycling lamp pattern will indicate
that the designated address is not communicating.
Rear Panel Audio Connections
Figure 1-5. Left side of rear panel
Audio connections are contained within the 26 pin high density D connector.
The audio can be analog, digital, or not installed depending on what was
purchased. See the ‘Card Installation’ section on page (1-6) to determine
which cards are installed in your system. Section 2 contains pinout
information for the ‘D’ connectors.

Card Installation
The BPS -2020 has two power supply slots and four slots for plug-in
cards. The following list shows which cards can be placed in which slots
1. Power Supplies – USI PN 140080-02.
2. Slot 1 – Either the 121188-2 8x1 crosspoint or the 121188-1
16x1 crosspoint can be installed in this slot.
3. Slot 2 – Either the 121182-1 video DA or the 121186-1 8x1
input card can be installed here. The 121182-1 should only
be used with the 121188-2 8x1 crosspoint, and the 121186-1
should only be used with the 121188-1 16 Input crosspoint.
4. Slots 3, 4 – either the BPS-2020 Digital Audio (121184-1)
crosspoint, the BPS-2020 Analog Audio Crosspoint
(121183-1), or the Deluxe Audio crosspoint can be placed
here.

Power Supplies
• The power supplies are calibrated at the factory. No field
adjustment is necessary.
• The supplies have Red LED’s that indicate failure of the 5V, 3.3V,
+-12V, integral fan and overtemperature. They also have a
bi-color LED that is green when all other failure leds are off, and
red when one or more of the other alarms trip.
