# 2 Getting Started

# 2.1 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 following items are included in the package.

▶ DLAP-201 unit
▶ Screw pack
▶ VESA mount kit (plus optional DIN rail kit if applicable)

# 2.2 Cooling Considerations

All heat-generating components of the DLAP-201 are located on the left side of the system. These components directly contact the heat sink via thermal pads to dissipate heat. To maximize efficiency of heat dissipation, maintain a minimum of 2 inches (5cm) clearance on the top of the DLAP-201.

# 2.3 Removing the Chassis Cover

To access the DLAP-201's internals, remove the underside of the chassis as follows.

1. On the front panel, remove the nut and washer from the DC12V connector and remove the two mounting screws, all indicated by red circles in the figure below.

![Front view of a ADLINK network device showing ports, connectors, and ventilation slots (no readable text or symbols beyond branding)](.dlap-201-jt2-50-1z308-1020-12/50274510fed42646c617b002e35d6e28350d5a49f601eb81c680553e82890ece.jpg)

2. On the underside of the device, remove the screw indicated by the red circle.

Reverse the steps above to replace the bottom cover.

# 2.4 Installing an mSATA Module

Use the following steps to install an mSATA module.

1. Insert the mSATA module into the indicated slot (under the wires) at an angle.

![ADLINK\nDAI-201-CB\n51-77B00.0\n5/N\n68T1B\n68T1B](.dlap-201-jt2-50-1z308-1020-12/eaa22a50f349f3ceedd64e9cf6aaa96e8545f1d1434198fd9a0f4d377da6b2cc.jpg)

Figure 2-1: mSATA Slot

# 2.6 Connecting DC Power

![The image shows a standard safety warning sign. It features a red triangle with a white exclamation point in the center. Below the triangle is a white rectangular area containing the text 'WARNING:' in black, uppercase letters.](.dlap-201-jt2-50-1z308-1020-12/bf5d418d21c2884c9f5278d2ee91c4de940426fd376e2d42003f209970ababdc.jpg)

Before providing DC power to the DLAP-201, 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-201 à une source de courant continu, veuillez vous assurer de la polarité de la tension conformément 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 circuits with no energy hazard, as well as the following:

▶ IEC 62368-1 + IEC 60950-1 + UL 62368-1
▶ Output voltage: 12 VDC
▶ Output current: 2.7A minimum
▶ TMA: 50°C minimum

The DLAP-201 DC power input connector uses V+, V-, and chassis ground pins and accepts input voltage as shown previously.

Customers may optionally order a DC power adapter from ADLINK: DC plug with lock (part no. 31-62156-1000-A0).

# 2.7 VESA Mount

The DLAP-201 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 keyhole-shaped 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 the screws are now firmly held by the narrower portions of the mounting holes.

# 2.8 DIN Rail Mount

The DLAP-201 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-201 chassis.

# 2.9 Internal Jumper Settings

The interior of the DLAP-201 controller features three jumper switches as shown in the figure.

▶ COM Mode Switches: SWS1601
▶ AT Mode Switch: SWS1501
▶ GPIO Switch: CN1501

![SWS1601\nSWS1501\nCN1501\nADLINK\nDLA-201-CB\n51-77800-0A20\n5/N\nCE\nRDTIB\nRDTIB](.dlap-201-jt2-50-1z308-1020-12/e3c4dc08fd7068daeb50be4bc25faab91f5c709dbb17abf3e4ebdc80eaa5015e.jpg)

Figure 2-5: Internal Jumpers

Detailed information for each switch appears in the sections below.

# 2.9.1 COM Mode Switches

The COM port's communication protocol is determined by jumper switches SWS1601. By default they are configured for RS-232 but may be changed to RS-422 or RS-485 by setting the pins as indicated in the table below.

<table><tr><td>Switch</td><td>Pin</td><td>RS-232 (default)</td><td>RS-422</td><td>RS-485</td></tr><tr><td rowspan="2">SWS1601</td><td>1</td><td>ON</td><td>ON</td><td>OFF</td></tr><tr><td>2</td><td>OFF</td><td>ON</td><td>ON</td></tr></table>

Table 2-1: COM Mode Switches

For instructions about setting the port's direction (TX/RX), see Section 3.3 COM Port Configuration on page 27.

# 2.9.2 AT Mode Switch (SWS1501)

The AT mode may be modified via SWS1501 as follows.

<table><tr><td>Pin</td><td>Default</td><td>TX1</td><td>TX2</td></tr><tr><td>1</td><td>OFF</td><td>ON</td><td>OFF</td></tr><tr><td>2</td><td>OFF</td><td>OFF</td><td>ON</td></tr></table>

# 3 Using the System

# 3.1 Software Configuration

The DLAP-201 ships with a customized NVIDIA Linux for Tegra (L4T) image pre-installed. The latest version of this custom L4T image and other relevant files are available on our website:

https://www.adlinktech.com/Products/Deep Learning Accelerator Platform and Server/Inference Platform/DLAP-201-JT2

For a non-customized version, download the TX2's "L4T Driver Package" directly from NVIDIA:

# 3.2 System Recovery

You will need a Linux host PC (Ubuntu is recommended) in order to flash your client device with a new system image. Complete the following steps on the client before performing the host PC steps.

# Client (DLAP-201-JT2):

1. Connect the OTG cable to the USB 2.0 port.
2. Press the reset and recovery buttons at the same time.
3. Press the power switch.
4. Release the reset button.
5. Release the recovery button.

# Host PC:

1. Install Python 2.7, python-minimal (or equivalent packages) and qemu-user-static on the host PC.

2. Connect the host PC to the client via OTG cable.

3. Open a terminal on the host PC and run this command:

\# lsusb

4. Look for "NVidia Corp." in the output (an example is circled in red in the screenshot below). If found, the host PC recognizes the client and you may proceed. If not, double-check the OTG cable connection and perform troubleshooting as needed until the client is recognized.

```txt

5. Now run the following commands in the directory that contains your downloaded L4T file:

```shell
# sudo tar xzvf Linux_for_Tegra.tar.gz
# cd Linux_for_Tegra
# sudo ./flash.sh jetson-tx2 mmcblk0p1
```

6. Allow the update to complete. For details about available command-line options, read the "flash.sh" file.

# 3.3 COM Port Configuration

By default, the DLAP-201 is configured to support the RS-232 protocol. For details about changing to RS-422/485, see Section 2.9 Internal Jumper Settings on page 23.

To set the direction to transmit (TX) or receive (RX), open a terminal within DLAP-201's Linux system and run these commands:

```shell
# sudo -s
# cd /sys/class/gpio
# echo 244 > export
# echo out > gpio244/direction
```

To set the direction to TX, run this command:

```markdown
# echo 1 > gpio244/value
```

Otherwise, to set the direction to RX, run this command:

```shell
# echo 0 > gpio244/value
# sty -F /Ddev/ttyTHS2 speed 115200
# echo "123456789" > dev/ttyTHS2
RX site commans (Receive data from the transmitter)
# cat &lt; /dev/ttyTHS2
```
