Connecting the FP-1001 to the Network
This section describes the network configurations possible with the
FP-1001 FieldPoint network module. The connector pinouts are
described in the RS-485 Interface Specifications section later in this
chapter.
One option for connecting the FP-1001 is to connect it to the RS-485
repeater port of an FP-1000 as shown in Figure 2-5. An alternative
method is to connect the FP-1001 directly to your host computer, if your
host computer provides an RS-485 interface (contact National
Instruments for information about available RS-485 hardware). You
can connect up to 25 FP-1001 network modules to each RS-485 port on
the host computer. This network configuration is shown in Figure 2-6.
