2.3 Ring Connection
The ring connection allows interconnecting several MCV1-FO using a ring. One of the devices must be the master and
the rest slaves.
To use the ring mode each of the MCV1-FO that connected to the slaves must have the Jumper of Configuration in
RING MODE in ON position, also the Master must have the RING MODE in OFF position.
Each MCV1-FO will be able to use the type of serial (RS232/RS422) that adapts to the equipment that goes connected
on it, with exception of the RS485 protocol, this is because the ring mode receives and transmits simultaneously
leaving the RS485 out for being a HALF DUPLEX protocol.
The data sent by the Master will be received and forwarded by all the slaves belonging to the ring. Finally this data
will arrive again up to the Master. Also every time a slave transmits something, all the slaves between the one that
transmitted and the Master, will receive the data too. To know which device will receive data, it is important to know
the data direction of them.
