The model F2812-COM-1 Dual
Fiber Optic Serial Port daughtercard allows the DSP developer to
add 2 optically isolated serial ports to the Spectrum Digital,
Inc. F2812 eZdsp™
development system. Each port has a maximum data rate of 921.6
kbps. Often, in motor
control or power supply control applications, it is necessary to
have remote access to the DSP without interfering with the
ground levels of the system being controlled. The model
F2812-COM-1 provides true galvanic isolation between the command
control (HMI, PLC, PC, etc) and the DSP system.
Easy to manage, 1mm plastic
fiber is used as the serial communication channel. This fiber
requires no special tools to cut, and does not require cut-end
polishing. Simply use an X-acto knife to cut the fiber to
length. The model F2812-COM-1 is supplied with two 3 ft. pieces
of fiber. Additional lengths of fiber are readily available at
electronic suppliers such as Digi-Key, etc.

Typical Application:
|
|
|
The above
figure illustrates a setup where one eZdsp™ is communicating
with another eZdsp™ using fiber optic cable. In this
example, the two eZdsp™'s are galvanically isolated from one
another. This setup eliminates any possibility of ground
loop issues, and avoids issues caused by the difference in
ground potentials between the two target systems. |
