# 4 Getting Started

# Unpacking Checklist

Before unpacking, check the shipping carton for any damage. If the shipping carton and/or contents are damaged, inform your dealer immediately. Retain the shipping carton and packing materials for inspection. Obtain authorization from your dealer before returning any product to ADLINK. Ensure that the fol- lowing items are included in the package.

 DLAP-211 unit
 Screw pack
 VESA mount kit (plus optional DIN rail kit if applicable)
 >60W Power adapter

# Cooling Considerations

All heat-generating components of the DLAP-211 are located on the left side of the system. These components directly contact the heat sink via thermal pads to dissipate heat. To maximize effi- ciency of heat dissipation, maintain a minimum of 2 inches (5cm) clearance on the top of the DLAP-211.

# Removing the Chassis Cover

To access the DLAP-211’s internal components, remove the underside of the chassis as follows.

1. On the front panel, remove the nut and washer from the 12V DC connector and remove the two mounting screws, as indicated in the figure below.

2. Press down on the module until it is seated, then secure it to the board using two M2.5-P-head-L5 screws (not provided).
3. Attach the wires and antennas that came with your Wi-Fi kit. It is recommended that the Wi-Fi antenna be connected to the left SMA antenna port, and Wi-Fi + Bluetooth antenna be connected to the right SMA antenna port.
4. Replace the bottom cover of the chassis.

# Connecting DC Power

![The image displays a safety warning symbol featuring a solid red, upward-pointing triangle containing a white exclamation point. Directly beneath the triangle, the word 'WARNING:' is printed in black capital letters.](.dlap-211-series-manual-50m-00016-1020-12/73da8b50da0b12ed10773e5693d983868ddfa0e58d7625150c63f447e9d6bdbf.jpg)

Before providing DC power to the DLAP-211, ensure the voltage and polarity provided are compatible with the DC input. Improper input voltage and/or polarity can be responsible for system damage.

Avant de connecter le PC DLAP-211 à une source de courant continu, veuillez vous assurer de la polarité de la tension con- formément à l'entrée CC du PC. Une tension et/ou une polarité incorrectes peuvent causer des dommages irréversibles sur le système.

DC power sources must comply with LPS and SELV (ES1) circuits with no energy hazard, as well as the following:

 IEC 62368-1, IEC 60950-1, and UL 62368-1
 Output voltage: 12V DC
 Output current: 5.0A minimum
 ${ \mathsf { T M A } } : 5 5 ^ { \circ } { \mathsf { C } }$ with DC input; $4 0 ^ { \circ } \mathsf { C }$ with adapter input
 Altitude Operability: 5000m minimum

The DLAP-211 DC power input connector uses V+, V-, and chassis ground pins.

Les sources d'alimentation CC doivent être conformes aux circuits LPS et SELV (ES1) avecaucun risque énergétique, ainsi que:

 CEI 62368-1, CEI 60950-1 et UL 62368-1
 Tension de sortie: 12V DC
 Courant de sortie: 5.0A minimum
 TMA: $5 5 \textdegree$ avec entrée $D C ; 4 0 ^ { \circ } C$ avec entrée adaptateur.
 Altitude de fonctionnement: min. 5000 mètres

Le connecteur d'entrée d'alimentation CC DLAP-211 utilise V+, V- et châssis broches de terre.

# VESA Mount

The DLAP-211 controller ships with a VESA 100 mounting bracket and four M4 screws. Follow the steps below to mount the device.

1 Attach the VESA bracket to the wall (or other suitable mounting surface) such that its keyholeshaped mounting holes are oriented with the wider openings at the top.
2 Secure the four M4 screws to the bottom of the chassis.
3 Securely attach the device to the VESA bracket by first inserting the heads of the screws into the wider openings of the VESA bracket’s mounting holes, then sliding the device down such that NOTEthe screws are now firmly held by the narrower portions of the mounting holes.

![This is an icon depicting a white document with horizontal gray lines and a folded top-right corner. A large red checkmark is superimposed over the document, indicating approval or completion. The entire graphic is enclosed within a thin black square border.](.dlap-211-series-manual-50m-00016-1020-12/3568ef460d85158e9f7413abe5eba1270aadc85e2c1d4a3453f92a4dbca4a0e5.jpg)
NOTE:

It is recommended that four M4 screws, 6cm in length, be used to attach the assembled brackets to a wall. Actual fastener type and length will be determined by the type of wall being anchored to. (Sample anchors M4x0.7 L8mm with washer.)

The DLAP-211 controller may optionally include a DIN rail mount kit, with its own six M4 screws, in addition to the standard VESA mount kit. Follow these steps to install the DIN rail bracket.

1. Use two M4 screws (pointing upwards in the red box below) to attach the DIN rail bracket to the adapter plate.
2. Use four M4 screws (circled in red below) to attach the DIN rail bracket assembly to the DLAP-211 chassis.

# Flash the System Image

Before flashing the image to NVIDIA Jetson Family, you should prepare the following items:

1. A Host PC with Ubuntu operating system.

2. A good quality OTG cable (micro-usb/USB type C) for connecting it to NVIDIA Jetson Family (Client PC).

Complete the following steps on the Client PC before performing the host PC steps:

# Client PC

1. Connect the OTG cable to the USB port.

2. Enter Recovery Mode

# Method 1: (Power on)

\$ sudo reboot --force forced-recovery

# Method 2: (Power off)

1. Press and hold the recovery button.

2. Press the power switch.

3. Press the reset button once and release it after 3-5 seconds.

# Recovery button

![RECOVERY RESET](.dlap-211-series-manual-50m-00016-1020-12/be5c11bf746db184ef7cca0944b7870d261659ff567098b994ea25ac9d6529d5.jpg)

# Host PC

The host must have the following dependencies:

\$ sudo apt install libxml2-utils simg2img network-manager abootimg sshpass device-treecompiler nfs-kernel-server

1. Connect the host PC to the Client PC via OTG cable.

2. Open a terminal, run the following command and check out the mode on the host PC:

\$ lsusb | grep NVIDIA

<table><tr><td>Recovery mode will show APX.</td><td>Normal mode will show L4T.</td></tr><tr><td></td><td></td></tr><tr><td>Bus 001 Device 031: ID 0955:7019 NVIDIA Corp. APX</td><td>Bus 001 Device 030: ID 0955:7020 NVIDIA Corp. L4T (Linux for Tegra) running on Tegra</td></tr></table>

• We need to make sure the client PC in recovery mode before flash image.

If client PC doesn't recognize or not in recovery mode, double-check the OTG cable connection and perform troubleshooting as needed until the client is recognized and in recovery mode.

3. Download the mfi file image into the Host PC.

ex: mfi\_jetson-orin-nano-dlap211-onx\_16-35.3.1-2v1.2.tbz2

4. Unzip the mfi file that was previously downloaded.

ex: \$ sudo tar -jxf mfi\_jetson-orin-nano-dlap211-onx\_16-35.3.1-2v1.2.tbz2

5. Go to the working folder.

ex: \$ cd mfi\_jetson-orin-nano-dlap211-onx\_16-35.3.1-2v1.2

6. Execute the flash command

ex: \$ sudo ./tools/kernel\_flash/l4t\_initrd\_flash.sh --flash-only

![The image features a white document icon with horizontal lines and a large red checkmark overlaid on it.](.dlap-211-series-manual-50m-00016-1020-12/7d1d7f482c61dd9a1b149f8f28c7b77a7abe691cabfa3a0280393dbfb67b3079.jpg)
NOTE:

In JetPack 5.0.2 and earlier versions of the MFI image, please execute the flash command:

\$ sudo ./nvmflash.sh

The following illustrates how to do the mass flash.

1. Connect Client PCs to the Host PC.

2. In the terminal, run lsusb to check that all Client PCs have entered into Recovery Mode.
