Figure 2-4. Connecting Terminal Bases
Connecting the FP-1000 to the Network
This section describes the network configurations possible with the
FP-1000 FieldPoint network module. The connector pinouts are
described in the RS-232 Interface Specifications and RS-485 Interface
Specifications sections later in this chapter.
Connect the RS-232 port of the FP-1000 to your host computer’s
RS-232 port. Use a 9-pin Dsub male-to-female “straight-through”
cable. Do not use a null modem cable (usually female-to-female).
You can connect only one FP-1000 network module for each RS-232
port in your host computer. You can add more FieldPoint banks without
using more RS-232 ports of your host computer, by connecting one or
more (up to 24) FP-1001 network modules to the RS-485 repeater port
of the FP-1000. This network configuration is shown in Figure 2-5.
