Install the Terminal Base(s)
CAUTION: Terminal bases must be connected to the network module
before applying power to the module. Do not connect or disconnect
terminal bases while power is applied to the network module.

D. Repeat for each terminal base, up
to nine for each network module in
most cases. You can use one or
two extender cables (which you can
order separately) if the FieldPoint
bank is too long for the available
space.
E. Place protective cover on last base,
and install rail locks at each end.
C. Slide into position and lock the rail
clip. Be careful not to bend any pins. D. Repeat for each terminal base, up to
nine for each network module in

Install the I/O Module(s)
A. Align slots on module with guide rails on
base, and press onto base until terminal
base’s latch locks the module in place.
B. Repeat for each I/O module.
It does not matter where you install each I/O module, except for
these types of situations:
··
·· If you plan to cascade power between any I/O modules using the
V and C terminals, those modules should be grouped together.
··
·· For more accurate measurements, you might want to locate any
thermocouple modules away from heat sources, including network
modules or relay modules, unless you are mounting them on an FP-TB-3.

Connect the Network Cables
You have several network connection options with the FP-1000 and FP-1001,
as shown here.
Connecting the FP-1000 to a Computer’s RS-232 Serial Port
Use a male-to-female (straight through) cable to connect the computer’s RS-
232 port to the 9-position DSub RS-232 connector on the FP-1000.
FP-1000
NOTE: You cannot connect the RS-485 port of the FP-1000 directly to an
RS-485 port on the computer.
If you are using multiple FieldPoint serial network modules, you may need to
connect the grounds of the RS-485 communication ports to each other to
prevent damage from differences in ground potentials.

4 120 Termination Resistors
You can connect up to 24 FP-1001 RS-485 serial network modules to an
FP-1000. Use the RS-485 repeater port of the FP-1000, with the connection shown
in this figure.
A. Connect the TX outputs of the FP-1001
to the RX inputs of the FP-1000, and
the RX inputs of the FP-1001 to the TX
outputs of the FP-1000.
B. Install the termination resistors.
Terminate each end of your RS-485
network using the 120 termination
resistors included with the FP-1001.
Install them between the RX and TX
pair of the FP-1000’s RS-485 port,
and between the RX and TX pair on the
last FP-1001’s RS-485 port, as shown.
Twist the resistor leads with the RS-485
signal wires and insert them into the
RS-485 port terminals.

Connecting the FP-1001 to a Computer’s RS-485 Serial Port
You may connect up to 25 FP-1001 network modules to a single RS-485 port of a
host computer. Use the connection shown in this figure.
A. Connect the FP-1001 to a host computer
using the 5-position Combicon screw
terminal adapter of the RS-485 connector
on the FP-1001.
B. Install the 120 termination resistors
included with the FP-1001. Install them
between the RX and TX pair of the host
computer’s RS-485 port, and between
the RX and TX pair on the RS-485
port of the last FP-1001 in the system,
as shown. Twist the resistor leads with
the RS-485 signal wires and insert
them into the RS-485 port terminals.
C. Check the biasing feature. The host
computer's RS-485 interface usually
provides for biasing resistors,
which are required on an
RS-485 network. You should
use this biasing feature for better
reliability and noise immunity.

Set the Network Address and Baud Rate
If the default values do not work for you, remove the switch cover from the
8-position switch on the front of the FP-1000/1001 to set the network
address and baud rate.

A. Check/Set the Network Address
Give every network module connected to one serial port of the host computer a
unique address, but modules on different serial ports may have the same address.
The addresses of the terminal bases connected to the network module are
automatically configured to be sequentially higher than the network module’s
address, moving out from the network module. The default network address
for the FP-1000/1001 is 0.
