GENERAL
The V1679 SINGLE-MODE FIBRE DATA TRANSCEIVERS form part of the Vistek V1600 range of fibre
interface products. Based on a 3U high baseboard, which is common to all members of the V1679 family, the
board can be fitted into a V1603 or V1606 rack, from which it receives its power and control.
A passive rear module is required for all electrical and optical signal interconnections.
The V1679 module is fully compatible with the Vistek DART remote control system.
Available V1679 models to date:
V1679/IO
Provides 8 General Purpose, opto-isolated Inputs and 8 General Purpose, earth-free Outputs.
All GP I/O's can either be driven externally or internally (DART controlled). All Inputs can be
monitored by DART.
V1679/IP
Provides 16 General Purpose, opto-isolated Inputs, with the choice of 8 Inputs to be triggered
either externally (Opto-Isolator Input) or internally (DART controlled). All 16 Inputs can be
monitored by DART.
V1679/OP
Provides 16 General Purpose Outputs, with the choice of 8 Outputs to be either driven
externally, i.e. driven through a corresponding signal sent from the remote site via the fibre link,
or internally (DART controlled).
Common to all models are two independently operating Serial Communication Ports, which can either be
configured to comply with RS-232 (single-ended) or RS-422 (differential) electrical standards.
Numerous RS-422 or RS-232 serial control applications can be now extended over long distances, with the
advantage of having an earth-free connection over fibre (no ground-loop problems) and negligible latency
(speed of light!).
A good example for using the V1679's RS-232 port is to remotely control a V1606 Rack over a single-mode
fibre link of up to 60km length.
With a wide choice of different CWDM Laser wavelengths available, the V1679 fits seamlessly in installations
with fibre links already in operation.
Together with the existing range of Advanced Fibre Interfaces (V1673/74 Series) and Passive Fibre
Distribution modules (V670x Series), the V1679 adds another building block to Vistek's total fibre solutions.
