Introduction
Congratulations on your purchase of the Maretron CKM12 12 Button Customizable Keypad.
Carling Technologies has proudly designed and built your CKM12 to the highest standards for
reliability and accurate service.
The CKM12 is a sealed, IP69K front rated, customizable keypad ready to deliver years of
dependable operation within the harsh demands of the marine environment. The CKM12 features
12 keys and a rubberized coating over the keypad. The CKM12 reduces installation time and the
complexity and cost of traditional wiring harnesses by utilizing NMEA 2000® CAN interface
technology.
The CKM12 connects directly to an NMEA 2000® network through the use of a CKM to NMEA
2000® Adapter Cable. Configure the CKM12 by using a Maretron USB100 or IPG100 tethering the
NMEA2000® network to a PC running N2KAnalyzer. Control MPower and other Maretron systems
with the CKM12 through an NMEA 2000® Network. Using standard NMEA 2000® messaging, the
CKM12 can illuminate any of its 12 blue LED lights for status of circuit state.
The CKM12 is available in 2 standard configurations. Custom configurations are available with a
minimum order quantity of 100 pieces.
Please carefully read and follow these instructions for installation, configuration, and usage of the
Maretron CKM12 module to ensure optimal performance.

Theory of Operation
Key position will be reported via the NMEA2000® Standard 127501 “Binary Status Report” CAN
message. Each button is considered a separate binary (on or off) switch and will be numbered as
follows:
Figure 1 - Key Numbering
There is a total of twelve blue LEDs, each configurable via CAN message to act as a function
indicator. The LEDs are located above the top row of keys and below the bottom row of keys. The
icons on each key are lit by an LED backlight located behind the icon. LEDs can be tied to a
channel of any device on the CAN network that reports the NMEA2000® standard 127501 “Binary
Status Report” message. When the associated channel reports it is in the “on” state, the LED will
be turned on and set to the function indicator brightness level. When the associated channel
reports it is in the “off” state, the LED would be extinguished.

Mounting the CKM12
Locate the panel mounting template supplied with the CKM12. After cutting panel mounting holes.
Place the CKM12 into panel cutout. The CKM12 mounting studs will protrude to the backside of the
panel hole. The use of silicone sealant is acceptable to provide extra sealing protection of the
CKM12 to the mounting panel. Thread supplied 10-32 nuts onto these threaded studs. Tighten to 30
In. lbs. Do not use permanent adhesive to install unit. Certain adhesives such as methacrylate will
cause cracking of the plastic enclosure. The use of permanent adhesive for installation will void
warranty of CKM12 unit. For reference to the needed panel cutout dimensions see Figure 6.
Figure 6 - Mounting Panel Cutout Dimension
Connecting the CKM12
Connecting the CKM12 consists of plugging the unit to the vessel’s NMEA 2000® network. The unit
can be connected to NMEA 2000 network directly to the 6 position Deutsch DT Series receptacle
molded into the unit or via use of the A3703 CKM to NMEA 2000® Adapter Cable.

NMEA 2000® Connection
The NMEA 2000® connector is the round five-pin male connector found on the VMM to NMEA
2000® Adapter Cable. This connector is known as a DeviceNet micro connector. You connect the
VMM6 to a NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by
connecting the female end of the cable to the male NMEA 2000 connector VMM to NMEA 2000®
Adapter Cable. (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 by plugging into the 6 position connector on the rear of the
CKM12, applying pressure until the connector latch clicks. The CKM12 is designed so 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.
NMEA 2000 connections can be made using pre-assembled leads or may be made using field
attachable connectors and cables (See: Figure 7).
