Abstract
Accra is a general counter module that connects to a CAN4VSCP bus and can count
pulses on four channels. The module can be attached to a standard
DIN Rail or be mounted directly on a wall.
The module fully adopts to the CAN4VSCP specification and can be powered directly
over the bus with a 9-28V DC power source. It has a rich register set for
configuration and any information events defined. It also have a decision matrix for
easy dynamic event handling.
VSCP CAN modules are designed to work on a VSCP4CAN bus which use
ordinary RJ-45 connectors and is powered with 9-30V DC over the same cable.
This means there is no need for a separate power cable. All that is needed is
a CAT5 or better twisted pair cable. Bus length can be a maximum of 500 meters
with drops of maximum 24 meters length (up to a total of 120 meters). As for all
VSCP4CAN modules the communication speed is fixed at 125 kbps.
All VSCP modules contains information of there own setup, manual, hardware
version, manufacturer etc. You just ask the module for the information you need
and you will get it.
When they are started up they have a default
functionality that often is all that is needed to get a working setup. If the
module have something to report it will send you an event and if it is setup to
react on a certain type of event it will do it's work when you send event(s) to it.
