Hardware Overview
The IVN-8561 has a total of four communication ports, and one USB port for power.
Ports 1 and 3 are 100BASE-T1 ports for Automotive Ethernet connections using two-
position terminal blocks. Ports 2 and 4 are 100BASE-TX ports for Ethernet
connections using 8-pin, modular RJ-45 connectors.
The 100BASE-T1 interfaces use an NXP TJA1100 100 Mbit/s BroadR-Reach-compliant
PHY. Weidmuller OMNIMATE SL-SMT 3.50/02/90LF terminal block headers are used
to connect to these ports. Compatible plugs are included with the IVN-8561.
Each 100BASE-T1 port can be configured as master or slave, using switches on the
front panel.

The power connector is USB Type-C. Use the USB cable (Type-C to Type-A) included
with the IVN-8561 to power the device from a standard USB 3.0 port on your
computer or industrial controller. The IVN-8561 can be powered from the USB port
of any NI PXI, CompactRIO, or industrial controller.
Cabling Requirements
Cabling for port 1 and port 3 connections must be 100BASE-T1 compliant, shielded
or unshielded twisted pair cable, with a maximum length of 15 m and cable
impedance of 100 Ω ±10%. Cabling for port 2 and port 4 connections must be Cat 5e
or higher Ethernet cable.
LEDs
LEDs on the le side of the front panel indicate Link and Activity on the 100BASE-T1
Automotive Ethernet ports. LEDs on the RJ45 connectors indicate Link, Activity, and
100 Mbit speed on the 100BASE-TX Ethernet ports.

1 100 Mbit link speed is the defauilt setting. This LED will be on steady even when no
cable is attached.
2 10 Mbit link speed is not supported. If this LED is o, packets will not pass through.
Master/Slave Switches
Switches on the le side of the front panel control master/slave selection for the
100BASE-T1 Automotive Ethernet ports.
Switch Description Position
P1 MASTER/SLAVE 100BASE-T1 port 1 master/slave selection Up: Master mode selected
Down: Slave mode selected
P3 MASTER/SLAVE 100BASE-T1 port 3 master/slave selection
To establish a link between two 100BASE-T1 ports, one port must be configured as
master and the other as slave. The IVN-8561 allows you to establish a link with a port
in any configuration by selecting the appropriate mode with the front panel switch.
When you change the MASTER/SLAVE switch selection, the IVN-8561 immediately
changes the configuration and resets the corresponding 100BASE-T1 and 100BASE-
TX ports for that channel. The master/slave configuration of one channel can be
changed without aecting the other.
DIN Rail Mounting
The NI 9913 DIN rail mounting kit (part number 781740-01) contains one clip for
mounting the IVN-8561 on a standard 35 mm DIN rail. The four holes on the bottom
of the IVN-8561 allow the device to be mounted in multiple orientations.
Fasten the DIN rail clip to the IVN-8561 using two FLH #6-32 x 5/16" screws (included
in the kit) with a #2 Phillips screwdriver, as shown in the following figure.

Wiring the IVN-8561
Terminal block headers are used to connect to the 100BASE-T1 ports. Compatible
plugs are included with the IVN-8561. Attach these plugs to twisted pair cabling to
connect a 100BASE-T1 network to ports 1 or 3 of the IVN-8561.
