S768DAV – S7768DAV User Manual Introduction
1 INTRODUCTION
This is a guide to the installation and operation of the S768DAV and S7768DAV series fiber optic video,
audio, data, and contact closure transmission system. Please read the entire manual before installing the
equipment.
NOTE: The series numbers S768DAVT and S768DAVR are used to describe all models of transmitters and receivers unless noted
otherwise.
The Series S768DAV and S7768DAV transmission systems offer simultaneous real-time transmission of:
! One channel of two-way 9-bit digital video
! Two channels of two-way high quality audio (HQA)
! Two channels of two-way multi-protocol data (MPD)
! Two channels of two-way relay/contact closures
The S768DAV system operates over one or two multimode fibers and the S7768DAV uses one or two
single-mode fibers. A complete system consists of an S768DAVT transmitter and an S768DAVR receiver.
Units are designed for installation in the 515R1 or 517R1 Card Cages or in the 502R rack card enclosure.
Figure 1 shows a basic system diagram.

2 MODULE SETUP
2.1 UNPACKING THE UNIT
In the event that anything is missing from the following list, contact your authorized dealer or
representative.
! S768DAVT (S7768DAVT) Transmitter or S7768DAVR (S7768DAVR) Receiver
! User Manual
Save the original packing materials in case it becomes necessary to return the unit.
CAUTION:
Take all necessary precautions to protect the unit from static electricity during the following procedures.
Equipment damage may result.
2.2 DATA TRANSLATION
The data translation capability of the S768DAV series is unique in the industry. It enables translation from
one data format to another and eliminates the need for external translation devices.
The translation is in the physical layer only; it cannot interpret specific protocols or translate commands.
Due to the encoding schemes utilized in Manchester and Biphase, these formats are exempt from
translation. Data translation examples are shown in Table 1.
Table 1. Data Translations
Translation TX Switch
Setting
TTL to RS232 three-wire 3 1 Signal level conversion
RS232, three-wire to TTL 1 3 Signal level conversion
TTL to RS422 3 4 Single ended to differential conversion
RS422 to TTL 4 3 Differential to single ended conversion
RS232, three-wire to RS422 1 4 Single ended to differential conversion
RS422 to RS232, three -wire 4 1 Differential to single ended conversion

RX Switch
Setting
Comments
RS485 to RS232, five-wire 7 – A 2 Tri-State detection circuitry activates handshaking bit
2.3 INPUT/OUTPUT DATA FORMAT
Determine the data formats required for input and output for both data channels. The data formats may
be the same or different for each channel. The data format can also differ from input to output on the
same data channel.
