What You Need to Get Set Up
1. Mount the cFP-1808
You can mount the cFP-1808 on a panel or in a standard 19 in. rack. Before using
either of these mounting methods, record the serial number from the back of the
cFP-1808.
Each set of mounting instructions in this document includes an instruction to
connect the protective earth (PE) ground terminal on the cFP-1808 to the system
safety ground. The PE ground terminal has the following symbol stamped beside
it: . Connect the PE ground terminal to the system safety ground using 14 AWG

(1.6 mm) wire with a ring lug. Use the 5/16 in. panhead screw shipped with the
backplane to secure the ring lug to the PE ground terminal.
Caution Keep in mind these requirements for space and cabling
clearance:
• Allow at least 51 mm (2 in.) all around the cFP-1808 for air
circulation.
• Allow 38 mm (1.5 in.) below and 51 mm (2 in.) above the I/O
modules.

Caution NI recommends that you use one of the mounting systems
described in this document. If you decide to use a custom mounting
solution, make sure that the screws you use are short enough to fit in the
holes in the backplane. The screw holes are 5 mm (0.2 in.) deep.

Mounting the Backplane on a Panel
1. Fasten the panel-mount plates to the back of the cFP-1808 using a number 2
Phillips screwdriver and the 8-32 ×
5/16 in. countersunk screws shipped with
the kit.
Caution Do not use screws longer than 5/16 in. to fasten the
panel-mount plates to the backplane.

2. Bolt or screw the panel-mount accessory to a panel.
3. Connect the PE ground terminal on the cFP-1808 to safety ground.
Caution Disconnect power before removing the backplane from the
panel.

2. Install I/O Modules on the Backplane
1. Align the captive screws on the
I/O module with the holes on the
backplane.
2. Press firmly to seat the I/O
module on the backplane.
3. Using a number 2 Phillips
screwdriver with a shank of at
least 64 mm (2.5 in.) length,
tighten the captive screws to
1.1 N · m (10 lb · in.) of torque.
4. Repeat this procedure to install
additional I/O modules on the
backplane.
3. Install Connector Blocks on the Backplane
In order to connect I/O modules to input signals or to external loads, you need to
install a cFP-CB-xconnector block or other connectivity accessory for each I/O
module on the backplane. Use the connector socket to the right of each I/O module
socket.
Caution Do not insert or remove connector blocks or other connectivity
accessories while power is applied to them.

1. Wire field devices as described in the I/O
module and connector block operating
instructions.
Caution Hazardous voltage wiring
should be performed by qualified
personnel and in accordance with
local electrical standards.
2. Align the captive screws on the connector
block with the holes on the backplane.
3. Press firmly to seat the connector block on
the backplane.
4. Using a number 2 Phillips screwdriver with a shank of at least 64 mm (2.5 in.)
length, tighten thecaptive screws to 1.1 N · m (10 lb · in.) of torque.
5. Repeat this procedure to install additional connector blocks on the backplane.
4. Connect the cFP-1808 to Your Network
You can connect the cFP-1808 to an Ethernet network, an RS-232 network, or
both.
Connecting the cFP-1808 to an Ethernet Network
In order to use the cFP-1808 on an Ethernet network, you must first configure the
cFP-1808 using MAX.
Connect the cFP-1808 to an Ethernet network using the RJ-45 Ethernet port on the
controller. Use a standard Category 5 Ethernet cable to connect the cFP-1808 to

an Ethernet hub, or use an Ethernet crossover cable to connect the controller
directly to a computer. Refer to Cabling in the Specifications section for pinouts
of the two types of Ethernet cable.
If the host PC is already configured on a network, you must configure the
cFP-1808 on the same network. If neither is connected to a network, you can
connect the two directly using a crossover cable.
In order for you to configure the cFP-1808, it must reside on the same subnet as
the host PC.
Caution To prevent data loss and to maintain the integrity of your
Ethernet installation, do not use a cable longer than 100 m. If you are
using a 100 Mbps Ethernet, National Instruments recommends using a
Category 5 shielded twisted-pair Ethernet cable.
Connecting the cFP-1808 to an RS-232 Serial Network
In order to use the cFP-1808 on a serial network, you must first connect it to a host
computer and configure it using MAX. Connect the RS-232 port of the cFP-1808
to the RS-232 port of the host computer. Use a 9-pin D-SUB male-to-female
straight-through cable. Do not use a null modem cable (usually female-to-female).
DIP switches 3–5 set the baud rate. Table 1 shows the switch positions and the
corresponding network baud rates.
Note The preconfigured setting of 115.2 kbps provides the fastest
performance, and you do not need to change this setting unless you
experience communication problems.
