1. Function introduction
1.1 Overview
Shenyang
Vhandy Technology Co., Ltd. GCAN-208 series module is an
industrial
integrated 1 (or 2) standard optical fiber interface (single-mode, multi-mode,
SC,
ST optional), 2 (or 1) standard CAN bus interface Level CAN bus to fiber optic
converter.
GCAN-208
series modules can convert CAN bus data into optical signals for
transmission
through optical fibers. By using GCAN-208 series modules in pairs,
users
can easily extend the CAN bus communication distance, effectively eliminate
long-distance
communication interference, and prevent the bus from being damaged
by
electromagnetic interference, ground ring interference, lightning strikes and other
damage
to the bus and equipment.
GCAN-208
series modules can convert CAN bus data transparently and losslessly
into
optical signals, and then parse the optical signals into CAN bus data transparently
and
losslessly. Vhandy Technology uses unique bus signal conversion
technology,
which can achieve the conversion time between CAN data and optical
signal
in microseconds, so as to ensure the real-time communication, so GCAN-208
can
support any CAN bus communication protocol Such as: CANopen, SAE J1939,
DeviceNet,
NMEA2000, etc.
The
unique dual-channel device of the GCAN-208-1 module can extend the
communication
distance of two CAN buses at the same time. The GCAN-208-2
module
has two sets of optical fiber interfaces, which can be used for cascading. This
series
of modules is a key tool for industrial bus transformation, long-distance
communication,
and isolation of bus interference. The CAN bus interface of the
module
has integrated an isolation protection module to prevent damage to the
module
due to instantaneous overvoltage and over current. At the same time, the
module
With the characteristics of small size, plug and play, etc., it is also the best
choice
for existing system integration.
