2.2 Connections
Use a straight-through CAT 5/6 Ethernet cable to connect the Digital I/O Card’s RJ-45
RabbitNet jack to a RabbitNet port on the master. You may use either port if you are con-
necting to a master such as the BL2500 that has more than one RabbitNet port.
NOTE: The RJ-45 RabbitNet jacks are serial I/O ports for use with a master and a net-
work of peripheral cards. The RabbitNet jacks do not support Ethernet connections.

Figure 4. Connect Digital I/O Card to Master
You will also have to provide two separate DC power supplies to your Digital I/O Card:
+5 V and a DCIN of 9–32 V. These power supplies are connected via the polarized
friction-lock terminal at header J9. You may assemble a suitable cable using the friction-
lock connectors from the Connectivity Kit described in Section 1.1.3. If you are using a
BL2500 or BL2600 as your master, you may draw this power from the BL2500 or
BL2600 as shown in Figure 4.
If you are using the digital outputs, you will need two additional external power supplies
up to 36 V that can each handle up to 1.6 A for +K1 and +K2. The actual voltage and
current depend on the requirements of the loads you plan to connect to the digital outputs.
These power supplies are connected to friction-lock terminals J1 and J4 on the Digital I/O
Card. You may assemble suitable cables using the friction-lock connectors from the Con-
nectivity Kit described in Section 1.1.3. See Section 2.2.1 for detailed wiring diagrams.
