IMPORTANT SAFETY INSTRUCTIONS
The lightning flash with arrowhead symbol within an equilateral triangle
is intended to alert the user to the presence of uninsulated “Dangerous
voltage” within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of
important operating and maintenance
(Servicing) instructions in the literature accompanying the product.
•Read this information
•Keep these instructions.
•Heed all warnings.
•Follow all instructions.
•Do not use this apparatus near water
•Clean only with dry cloth.
•Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions
•Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
•Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two
blades with one wider than other. A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
•Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles
and the point where they exit from the apparatus.
•Only use attachments/accessories specified by the manufacturer
•Unplug this apparatus during lightning storms or when unused for long periods of time.
•Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC –
SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE
WARNING
DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING AND ENSURE THAT NO
OBJECTS FILLED WITH LIQUIDS ARE PLACED ON THE EQUIPMENT
WARNING
TO COMPLETELY DISCONNE
CT THIS EQUIPMENT FROM THE AC MAINS, DISCONNECT THE

7700ACO-HD HD/SD SDI 8 Channel AES & RS-232/RS-422 Auto Changeover
Revision 1.3 Page 1
1. OVERVIEW
The 7700ACO-HD HD/SD SDI Auto Changeover is designed to provide a HD/SD SDI video, multi-channel
AES audio, and RS422/RS232 changeover in a single device. The module can be controlled via GPI,
remotely via VistaLINK® PRO, or be set in auto changeover mode. It is an all-in-one ACO package aimed
towards protecting a complete channel (i.e. video, 8 unbalanced AES, and associated control channel
(RS232 or RS422)). The unit also features latching relays that maintain state through a loss of power.
VistaLINK®enables control and configuration capabilities via Simple Network Management Protocol
(SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP
enabled control systems such as Evertz VistaLINK®.
Features:
•Auto detection of signal standard
•Four modes of operation:
•Auto changeover - two standalone auto changeovers
•Manual DIP switch control - two independently controlled 2x1 switchers
•GPI Control - two independently GPI controlled 2x1 switchers
•Tally output provided
•Protection for 8 channels of AES
•Control channels
•Protection (on HD (1.5Gb/s) or SD (270Mb/s)
•Changeover conditions are based on signal presence of:
•HD/SDI (TRS timing, CRC and EDH)
•DVB-ASI (SMPTE sync word); Sync (H timing) and AES (sync word)

Please note: Early versions supported changeover of analog composite and tri-
level signals.
•VistaLINK®-capable offering remote monitoring, control and configuration capabilities via SNMP
•VistaLINK®is available when modules are used with the 3RU 7800FR frame and a 7700FC
VistaLINK®Frame Controller module in slot 1 of the frame

2. INSTALLATION
The 7700ACO-HD comes with a companion rear plate that occupies two slots in the frame. For
information on mounting the rear plate and inserting the module into the frame see section 3 of the
7700FR chapter.
Figure 2-1: Rear Panel
2.1. VIDEO CONNECTIONS
HD/SDI INPUT A and B: The input BNC connector for 10-bit serial digital video signals compatible
with the SMPTE 292M, SMPTE 259M, or SMTPE 310M standard.
HD/SDI OUT: This BNC connector is used to output the video as serial component video,
compatible with the SMPTE 292M or SMPTE 259M standard (same as
input) with embedded audio.

Unused HD/SDI OUT connectors MUST BE terminated with 75 ohms for proper
operation. If it is not terminated, in some cases relays MAY oscillate.

2.2. AES IN AND OUT CONNECTIONS
There are two high-density DB-15 connectors labeled AES IN A and AES IN B.Each connector provides
eight unbalanced AES inputs on 8 BNC connectors. There is a third high-density DB-15 connector
labeled AES OUT. The connector provides eight unbalanced AES outputs on 8 BNC connectors. These
inputs and outputs are for unbalanced AES signals conforming to SMPTE 276M. Table 2-1 and Table 2-2
shows the DB-15 connector pin out.

There is a terminal block that allows the user to connect either RS232 or RS422. COM IN A and COM IN
Bare used for connecting two RS232/RS422 as inputs. COM OUT is used for connecting RS232/RS422
as an output. The input cables can be secured into the removable portion of the terminal strips using a
small screwdriver. The removable part of the terminal strip is then inserted into the rear panel and can be
secured using the hold down screws. The terminal block pin out for the control connections is shown in
Figure 2-2.
