3.6.6 Ethernet Interface
The Ethernet interface can be used for TCP/IP communication with a remote or local host computer by connecting the
reader to either a LAN or directly to a host PC. There is no need to use a crossover adapter since ABR incorporates an
auto-cross function.
A STP-M12D-4xx can be used to connect to a LAN.
On the ABR Ethernet interface the following communication channels are available:
• TCP Client
• TCP Server
• UDP Channel
• FTP Client
The following Industrial Ethernet protocols are also available over the Ethernet interface:
• EtherNet/IP
• Modbus TCP Client
3.7 TCNM-ACBB1 Electrical Connections
All ABR models can be connected to a TCNM-ACBB1 connection box through the MQDEC-1703SS-DB25 accessory cable.
This cable terminates in an M12 17- pin connector on the ABR side and in a 25-pin male D-sub connector on the TCNM-
ACBB1 side.
Make system connections through one of the TCNM-ACBB1 connection boxes because they offer the advantages of easy
connection, easy device replacement, opto-isolated outputs (Outputs 1 and 2), and filtered reference signals.
Note: If you require direct wiring to the reader, the connections are the same as shown in this section with
the exception of the digital Outputs. Direct wiring details are indicated in
16.
The table below gives the pinout of the TCNM-ACBB1 terminal block connectors. Use this pinout when the ABR is
connected by means of the TCNM-ACBB1.
