3.2 Connections
Use a straight-through CAT 5/6 Ethernet cable to connect the A/D Converter 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 boards. The RabbitNet jacks do not support Ethernet connections.
Some masters have only
one RabbitNet port and
do not have a friction-lock
power terminal.

You will also have to provide +5 V DC power to your A/D Converter Card. The power
supply is connected via the friction-lock terminal at header J2. 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 18. You may assemble a suitable cable using the friction-lock connectors
from the Connectivity Kit described in Section 1.1.3. Although there is a standard Rabbit-
Net DCIN power-supply input on the A/D Converter Card, the A/D Converter Card does
not need DCIN power.
NOTE: Even if you are not drawing power from a master, you will need to connect the
A/D Converter Card ground to the ground on your master. The GND pin on header J2
should be used.
At the present time, you are limited by the number of RabbitNet ports on the master as to
how many peripheral boards may be connected to that master.
