COMMUNICATION BOARD RSs-485 (MC-2004)

COMMUNICATION BOARD RS-485 (MC-2004)

Description
Board for connexion of several peripheal
that require RS-485 protocol, has 2
independent gates “with intern protocol
adaptable to users needs”. Its frontal part is
made up of:
•
•

2 inputs for RS-485 lines
4 LED diodes for each gate, to inform
about the communication state:
TXD (transmission)
RXD (reception)
WATCH DOG (check) ERR (error in line)

Application
Peripheral that present open and flexible
RS-485 protocol for its communication.
•
•
•

Display controller.
Motors sep by sep.
Etc.

It can be used as master communication
board.

Additional data
Europe board format.
2 communication channels, each of
them ruled by a microprocessor.
2 kbytes dualport to communicate with
the CPU.
CPU opto-isolated channels. Made up
of one DC/DC stage, 3 opto-isolated
and
integrateds
for
RS-485
communication.
Information
about
each
gate
communication state through LED
diodes.
• TXD: usually (FLASHING)
• RXD: usually (FLASHING)
• WD: usually (FLASHING)
• ERR: usually (OFF)

Common data
Ending line resistor with switch.

Device base address according to
board position on the RACK.
