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 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.

It does not matter where you install each I/O module, except in the following cases:
• 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, place thermocouple modules away from heat sources,
including network modules or relay modules.
A. Align slots on the module with the guide rails on the base, and press the module onto base
until the terminal base latch locks the module in place.
B. Repeat for each I/O module.

The FP-1300 ships with the standard base arbitration ID 0x0. The FP-1300 sequentially allocates
the I/O channel arbitration IDs from the base arbitration ID of the FP-1300. If you are not using
the FP-1300 software and need to configure a different base arbitration ID, use the DIP switches
on the FP-1300 module. For more information about using DIP switches to configure the
arbitration ID, refer to the
FP-1300 User Manual.

CC
CCAA AAUU UUTT TTIIIIOO OONN NN Before you connect the FP-1300 to a CAN network, make sure the baud
rates of the FP-1300 and the CAN network are the same. The default baud rate of the
FP-1300 is 500 Kbps. If you are configuring the FP-1300 for the first time and the CAN
network is operating at a baud rate other than 500 Kbps, configure the FP-1300 to
operate at the appropriate baud rate before you install it on the CAN network. If you do
not, CAN network errors can occur, and other CAN devices on the network can go into
an error state. For more information, refer to the
Configuring the Baud Rate section of
the FP-1300 Configuration Utility Help.

Connecting the CAN Cable to the FP-1300
To connect an FP-1300 bank to the CAN network, complete the following steps.
A. Plug the Combicon-style connector into the CAN port.
B. Connect a shielded twisted-pair cable to the C_H and C_L terminals. Connect the shield of
this cable to the SH terminal. Refer to ISO 11898-2 for the maximum cable length between
the FP-1300 and the CAN network. C_H and C_L carry the data on the CAN network. For
noise immunity, solidly ground the shield of the cable as closely as possible to the FP-1300.
C. Connect a 10–30 VDC power supply to the V+ and V– terminals. V+ and V– supply power to
the CAN transceivers on the FP-1300.
D. Connect the other end of the CAN cable to a connector on the CAN network.

Terminating the CAN Network
If you connect the FP-1300 to a multiple-device CAN network that is already terminated, go to
the Wire Power to the FieldPoint System section next. If you connect the FP-1300 to a single-
device CAN network, you need to terminate the network. To terminate the CAN network, follow
these steps:
A. Install a 120 Ωresistor between the C_H and C_L terminals on the FP-1300. The typical
resistance is 120 Ω. The maximum resistance is 130 Ω. The minimum allowable resistance
is 100 Ω.
B. Install another 120 Ωresistor at the other end of the CAN cable between the C_H and C_L
terminals.
When you terminate the CAN network, the effective resistance between C_H and C_L is 60 Ω.
NN
NNOO OOTT TTEE EE The Combicon-style connector and the CAN cable must have a nominal
impedance of 120 Ω. For more information, refer to ISO 11898-2.

A. Connect 11–30 VDC power supply leads to either set of the V and C terminals on the
network module. If you want to verify that the power supply is sufficient for the modules
and devices, refer to the FieldPoint hardware documents for instructions on calculating
power requirements.
B. Connect power to the FieldPoint modules that require external power for outputs (output
modules, counter modules, PWM, PG, QUAD). Refer to the I/O module operating instructions
for power consumption details. You can power a module by connecting the V and C inputs on
its terminal base to a separate power supply, connecting the V and C outputs of a
neighboring terminal base or network module, or using a combination of both methods.
