The model F2812-COM-2 is an
RS-232 to optical fiber serial port converter. It is designed to
be used in conjunction with the model F2812-COM-1 dual port
fiber optic serial port daughtercard. Together, these products
allow a PC, PLC, HMI or other processor based controller to
commuincate with the eZdsp™ development system in an optically
isolated manner. The
model F2812-COM-2 is a stand alone board and is supplied with a
5 Volt, desktop power supply. Also, a 6 foot DB-9 RS-232 cable,
and two 3 foot lengths of fiber are included with the product.
The Link Research model
F2812-COM is a dual RS-232 serial port daughtercard designed to
operate with the F2812 eZdsp™ development system from Spectrum
Digital, Inc.

Typical Application:
|
 |
|
The above
figure illustrates a setup where the PC is communicating
with the eZdsp™ using fiber optic cable. In this example,
the PC is galvanically isolated from the eZdsp™ target
system. This setup eliminates any possibility of ground loop
issues, and avoids issues caused by the difference in ground
potentials between the PC system and the target system.
Also, any conducted EMI generated by the PC system is not
introduced into the DSP target system. |
