ATTENTION: Risk of equipment damage exists. Remove power before
installing or removing the 1769-SM1 module. When you install or remove
the module with power applied, an electrical arc may occur. An electrical
arc can cause personal injury or equipment damage by:
•Sending an erroneous signal to your system’s field devices, causing
unintended machine motion.
•Causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
!
ATTENTION: Risk of equipment damage exists. The 1769-SM1
module contains ESD (Electrostatic Discharge) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static control
precautions are required when handling the module. If you are unfamiliar
with static control procedures, refer to Guarding Against Electrostatic
Damage, Publication 8000-4.5.2.

Step 2 Set the 1769-SM1 module Configuration Mode switch to an appropriate
position. For complete switch setting details, see the 1769-SM1 module
User Manual.
Step 3 Assemble the 1769-SM1 module to the controller. It can be attached to
adjacent controller modules before or after mounting. For mounting
instructions, see Step 4A (Panel Mounting) or Step 4B (DIN Rail
Mounting). To work with a system that is already mounted, see Step 5.
A. Disconnect power.
B. Install the 1769-SM1 module within 6 slots of the power supply.
C. Check that the bus lever (item 1) of the 1769-SM1 module is in the
unlocked (fully right) position.
D. Use the upper and lower tongue-and-groove slots (item 2) to secure the
modules together.
E. Move the 1769-SM1 module back along the tongue-and-groove slots
until the bus connectors (item 3) line up with each other.
F. Use your fingers or a small screwdriver to push the bus lever back
slightly to clear the positioning tab (item 4).
G. Move the 1769-SM1 module’s bus lever fully to the left (item 5) until it
clicks. Ensure it is locked firmly in place.
H. Attach an end cap terminator (item 6) to the last module in the system
by using the tongue-and-groove slots as before.
I. Lock the end cap bus terminator (item 7).
Important: A 1769-ECR or 1769-ECL right or left end cap must be used
to terminate the end cap of the serial communication bus.

ATTENTION: Risk of equipment damage exists. When
attaching the 1769-SM1 module to a Compact I/O system, it is
very important that the bus connectors are securely locked
together to ensure proper electrical connection. Failure to do
this may cause an electrical arc, which can cause personal
injury or equipment damage.

Step 4 Mount the 1769-SM1 module.
Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.
Allow 50 mm (2 in.) of space on all sides for adequate ventilation as shown.
Allow at least 140 mm (5.5 in.) of enclosure depth to accomodate the
1769-SM1 module.
A. Panel Mounting — Mount the 1769-SM1 module to a panel using two
screws per module. Use M4 or #8 panhead screws. Mounting screws are
required on every module.
Using a Dimensional Drawing
NOTE: All dimensions are in mm (inches). Hole spacing tolerance:
± 0.04 mm (0.016 in.).

ATTENTION: Risk of equipment damage exists. During
panel or DIN rail mounting of all devices, be sure that all debris
(metal chips, wire strands, etc.) is kept from falling into the
1769-SM1 module. Debris that falls into the module could
cause damage on power up.

Using Module as a Template
The following procedure enables you to use the assembled modules as a
template for drilling holes in the panel. Due to module mounting hole
tolerance, it is important to follow these steps:
a. On a clean work surface, assemble no more than three modules.
b. Using the assembled modules as a template, carefully mark the
center of all module-mounting holes on the panel.
c. Return the assembled modules to the clean work surface, including
any previously mounted modules.
d. Drill and tap the mounting holes for the recommended M4 or #8
screw.

e. Place the modules back on the panel, and check for proper hole
alignment.
f. Attach the modules to the panel using the mounting screws.
B. DIN Rail Mounting — The 1769-SM1 module can be mounted using
the following DIN rails:
•35 x 7.5 mm (EN 50 022 - 35 x 7.5)
•35 x 15 mm (EN 50 022 - 35 x 15)
Before mounting the module on a DIN rail, close the DIN rail latches.
Press the DIN rail mounting area of the module against the DIN rail.
The latches will momentarily open and lock into place.
Step 5 Replacing the module within a system. The 1769-SM1 module can be
replaced while the system is mounted to a panel (or DIN rail).
A. Remove power.
B. Unplug the 1202-C* communications cable from each port (CH1, CH2,
CH3) on the 1769-SM1 module. Note each drive and the port to which
it is connected.
C. Remove the upper and lower mounting screws from the module (or
open the DIN latches using a flat-blade screwdriver).
D. On the right-side adjacent module, move its bus lever to the right
(unlock) to disconnect it from the module being removed.
E. Gently slide the disconnected 1769-SM1 module forward. If you feel
excessive resistance, make sure that you disconnected the module from
the bus and that you removed both mounting screws (or opened the DIN
latches).
!
ATTENTION: Risk of equipment damage exists. Remove
power before installing or removing the 1769-SM1 module.
When you install or remove the module with power applied, an
electrical arc may occur. An electrical arc can cause personal
injury or equipment damage by:
•Sending an erroneous signal to your system’s filed devices,
causing unintended machine motion.
•Causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
TIP: It may be necessary to slightly move the module from
front to back to remove it, or in a panel-mounted system, to
loosen the screws of adjacent modules.

F. Before installing the replacement 1769-SM1 module, be sure that the
bus lever on the right-side adjacent module is in the unlocked (fully
right) position.
G. Slide the replacement 1769-SM1 module into the open slot.
H. Connect the 1769-SM1 module and adjacent modules together by
locking (fully left) the bus levers on the 1769-SM1 module and the
right-side adjacent module.
I. Replace the mounting screws (or snap the module onto the DIN rail).
J. Plug the appropriate 1202-C* communications cable into its respective
port on the 1769-SM1 module.
K. Restore 1769-SM1 module configuration using an appropriate
configuration tool.
Step 6 Connect the module to the drive(s).
A. Plug one male end of a 1202-C* communications cable into a desired
port (CH1, CH2 or CH3) on the 1769-SM1 module.
B. Plug the other male end of the cable into the port on the desired drive.
NOTE: For EMC regulatory compliance, there is a maximum cable
distance limit per channel. See the “Regulatory Compliance” section in the
1769-SM1 Compact I/O to DPI/SCANport Module User Manual for more
information. For general cable information, see the “DPI/SCANport Cable
Requirements/Recommendations” section in the 1769-SM1 module User
Manual.
Step 7 Ground the module.
The 1769-SM1 module is intended to be mounted to a well-grounded
mounting surface such as a metal panel. Additional grounding connections
from the module’s mounting tabs or DIN rail (if used) are not required
unless the mounting surface cannot be grounded. For additional
information, refer to Industrial Automation Wiring and Grounding
Guidelines, publication No. 1770-4.1.

Step 8 Apply power.
A. Apply power to the controller. The status indicators can be viewed on
the front of the 1769-SM1 module after power has been applied.
B. The module is assigned a unique network address by the bus master
during initialization.
C. Apply power to the drive. When you apply power to the 1769-SM1
module, controller, and network for the first time, the status indicators
should be green after an initialization. If the status indicators go red,
there is a problem. Refer to the “Troubleshooting” chapter in the
1769-SM1 Compact I/O to DPI/SCANport Module User Manual.
Step 9 Read the 1769-SM1 Compact I/O to DPI/SCANport Module User Manual
for information to configure and determine how to apply the network to the
host product(s).
!
ATTENTION: Risk of equipment damage, injury, or death
exists. Unpredictable operation may occur if you fail to verify
that parameter settings are compatible with your application.
Verify that settings are compatible with your application before
applying power to the drive.
