2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron DSM250, you should find the following items:
•1 – DSM250 NMEA 2000®Multi-function Graphic Display
•4 – Mounting studs
•4 – Mounting washers
•4 – Mounting lock washers
•4 – Mounting knurled nuts
•1 – DSM250 User’s Manual
•1 – Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
The DSM250 is housed in a waterproof enclosure (IEC IP67 rating – protected against the effects of
temporary immersion in water) and can be mounted in either an outdoor location or an indoor
location.
2.3 Mounting the DSM250
The DSM250 has three mounting options, which includes surface mounting, flush mounting, or an
optional gimbal mounting. Maretron suggests a location at which the display can be viewed from a
relatively straight angle, and at which the keys are easily pressed.
2.3.1 Surface Mounting the DSM250
The DSM250 can be directly mounted to any suitable surface as shown in Figure 1. The steps for this
type of mounting are as follows:
1. Attach the Surface Mount Template (see Section 13) to the surface where the DSM250 is to be
located.
a. Make sure the template is level by using one of the horizontal lines as a guide.
b. Scotch tape works well for securing the template.
c. The maximum thickness of the mounting material should not exceed 1¼” using the
provided mounting studs, thicker surfaces can be accommodated but you will need to
purchase longer studs.
2. Drill the four mounting holes all the way through the mounting surface at the locations
indicated on the Surface Mount Template.
a. Use a 3/16” drill bit.
3. Drill or cut a single hole for the electrical connector.
a. Use a 2¼” hole saw.
b. You will probably want this hole to be large enough for your fingers so that you can
connect or disconnect the cable without removing the DSM250.
4. Remove the template from the mounting surface.
5. Insert the 2” studs into the back of the DSM250.

Revision 1.4.2 Page 3
a. Make sure the studs are fully inserted into the back of the DSM250 but don’t over tighten
the studs.
6. Insert the studs protruding from the back of the DSM250 through the mounting holes and
secure with the provided hardware.
a. Place the flat washer on the stud first followed by the lock washer followed by the knurled
nut.
b. Hand-tighten the knurled nut.
Figure 1 – Surface Mounting the DSM250
2.3.2 Flush Mounting the DSM250
The DSM250 can be flush mounted to any suitable surface as shown in Figure 2. The steps for this
type of mounting are as follows:
1. Attach the Flush Mount Template (see Section 13) to the surface where the DSM250 is to be
located.
a. Make sure the template is level by using one of the horizontal lines as a guide.
b. Scotch tape works well for securing the template.
c. The maximum thickness of the mounting material should not exceed 1¼” using the
provided mounting studs, thicker surfaces can be accommodated but you will need to
purchase longer studs.
2. Cut out an opening as indicated on the Flush Mount Template.
a. Sorry, we should have made the flange larger, but be very careful not to go outside the
indicated cutout area. Be on the safe side and cut the hole a little small and rasp or file to
fit.
3. Remove the template from the mounting surface.
4. Insert the 2” studs into the back of the DSM250.
a. Make sure the studs are fully inserted into the back of the DSM250 but don’t over tighten
the studs.
5. Remove the back of the case from the DSM250.

DSM250 User’s Manual
Page 4 Revision 1.4.2
a. Place your thumbs on top of the studs and your finger along the side of the case and
squeeze the back cover off the DSM250.
6. Insert the back of the DSM250 through the front side of the cutout.
7. Place the back cover on the opposite side of the mounting surface with the mounting holes
aligned with the mounting studs and secure with the supplied hardware.
a. Place the flat washer on the stud first followed by the lock washer followed by the knurled
nut.
b. Hand tighten the knurled nut.

2.3.3 Gimbal Mounting the DSM250
The DSM250 can be gimbal mounted to any horizontal surface such a counter or ceiling as shown in
Figure 3. The optional gimbal mounting assembly (part number DSMMNTASSBLY) includes a
bracket and screws for attaching the bracket to the DSM250, a stand, and 2 knobs for fastening the
DSM250/bracket to the stand.

2.4 Connecting the DSM250
The Maretron DSM250 provides a connection to an NMEA 2000®interface through a connector that
can be found on the back of the unit. The NMEA 2000®connector is a five pin male connector (see
Figure 4). You connect the DSM250 to an NMEA 2000®network using a Maretron NMEA 2000®
cable (or compatible cable) by connecting the female end of the cable to the DSM250 (note the key
on the male connector and keyway on the female connector). Be sure the cable is connected
securely and that the collar on the cable connector is tightened firmly. Connect the other end of the
cable (male) to the NMEA 2000®network in the same manner. The DSM250 is designed such that
you can plug or unplug it from an NMEA 2000®network while the power to the network is connected
or disconnected. Please follow recommended practices for installing NMEA 2000®network products.

2.4.1 Checking the Connection
Once the NMEA 2000®connection to the Maretron DSM250 has been completed, observe the
display to check to see that information is being properly received. One way to verify connectivity is to
enter the device selection menu, which is described in Section 5.2.3.2. Refer to Section 10,
“Troubleshooting”, if no information appears.

3 Operating the DSM250
3.1 Turning the DSM250 On
To turn on the DSM250, press the power key (the leftmost of the five keys on the keypad). The
DSM250 will display a warning and ask you to press the Accept key ( ) to acknowledge the
warning and continue operation of the DSM250 (see Figure 5 below).
Figure 5 – DSM250 Power Up Screen
Alternatively, you may power down the DSM250 by pressing and holding the power key (see Section
3.2 below for details).
3.2 Turning the DSM250 Off
To turn the DSM250 off, press and hold the power key. The DSM250 will display a countdown
screen, which can be seen in Figure 6. If you continue to hold the power key, the DSM250 will power
down in approximately three seconds. If you release the power key before these three seconds have
elapsed, the DSM250 will return to its current operational state.
