Reader/Writer connector
This connector connects to the connector on the Reader/Writer or to the V680S-A40 @M Extension
Cable.
Ethernet Connector Lines
These lines are connected to an Ethernet connector to supply power and the control signal to the
Reader/Writer. The Reader/Writer supports for Auto-MDIX, can communicate by both straight and
cross ethernet lines.
If an Ethernet network is configured into a loop as shown below, broadcast packets are accumulated in the band, and the
communication is disabled. Therefore, do not configure the Ethernet network into a loop.
When a large amount of broadcast packets or multicast packets flow into the Ethernet network, Reader/Writers may stop its
operation. Please do not send a large amount of packet. Please separate the Reader/Writers from the network segment that
broadcast or multicast packets flow.
