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 affecting 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.
