Installing the Maretron TLA100 involves the following steps. Please refer to the individual 
sections for additional details. 
 

1.  Unpack the Box (Section 2.1) 
2.  Choose a Mounting Location (Section 2.2) 
3.  Connect the TLA100 (Section 2.3) 
4.  Configure or Program the Tank Type (Section 3.1) 
5. Configure or Program the Tank Number (Section 3.2) 
6. Configure or Program the Operating Mode (Section 3.3) 
7.  Configure or Program Tank Capacity (Section 3.4) 
8. Configure or Program the Resistive Sender type: American or European (Section 3.5.1) 
9.  Optional – Custom Calibration (Section 3.5.2) 

 

2 Installation 

2.1  Unpacking the Box 

When unpacking the box containing the Maretron TLA100, you should find the following items. 
 

  1 - TLA100 Tank Level Adapter 

  1 - TLA100 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 primary function of the TLA100 is to adapt commercially available resistive tank senders to 
an NMEA 2000

®

 network so that tank level information can be viewed anywhere on the vessel 

where there is an NMEA 2000

®

 compatible display. The TLA100 can be used together with an 

analog gauge(s) (referred to as 

NMEA 2000

®

 / Analog Gauge Mode

), or it can be used 

standalone to power and sense the resistive sender without an analog gauge(s) (referred to as 

NMEA 2000

®

 Mode

). If you are using the TLA100 with an analog gauge(s) then refer to 

Section 2.2.1 for determining an appropriate mounting location and skip Section 2.2.2. If you 
are using the TLA100 as a standalone adapter without attaching an analog gauge, then skip 
Section 2.2.1 and refer to Section 2.2.2 for determining an appropriate mounting location. 
 

2.2.1  Mounting Location When Used With Analog Gauge(s) 

The TLA100 has two primary connections: 1) the NMEA 2000

®

 network connection, and 2) the 

analog gauge connection. Therefore, the TLA100 should be located between the NMEA 2000

®

 

trunk line and the analog gauge(s). The reason for choosing this location is because you will 
be connecting some of the wires within the TLA100’s permanently attached gray cable to the 
gauge and not the actual sender located at the tank. Maretron recommends placing the 
TLA100 within 15 feet of the gauge so the TLA100’s permanently attached gray cable can be 
directly connected to the gauge without any splices (see Figure 1). You may also consider 
placing the TLA100 as close as possible to the NMEA 2000

®

 trunk line so you can purchase
