Frequently Asked Questions - DEX5950 AOPEN

How do I install an external power switch?

Use the terminal block at the rear labeled 'Extend Power SW'. Insert wires (AWG 20-28, strip length 9-10mm) by pressing the button on the terminal, inserting the wire, and releasing. Connect to a momentary switch. The PS_ON signal goes low when power is on.

Can I use RS422/485 on COM4?

Yes, COM4 supports RS232, RS422, and RS485. The mode can be selected in BIOS. Refer to the pin definitions in the manual for correct wiring.

What memory type does the DEX5950 support?

It supports 1x SO-DIMM DDR5 at 4800 or 5200 MHz, with a maximum capacity of 32GB.

How do I clean the DEX5950?

Disconnect the power adapter before cleaning. Use a soft, moist cloth (not wet). Do not use liquid or spray cleaners. Avoid getting moisture into any openings.

What are the ventilation requirements?

The DEX5950 is fanless. Ensure at least 5 cm (2 inches) of clearance on the right side and rear for proper airflow. Do not place it in an enclosed space.

Can I install a 4G LTE module?

Yes, there is a dedicated M.2 2242 slot (key B) for a 4G LTE module. Additionally, there is an M.2 2230 slot for WiFi and an M.2 2280 for NVMe/SATA SSD.

What is the maximum RAM capacity?

The maximum memory size is 32GB using a single DDR5 SO-DIMM module.

How do I connect an external power switch?

Use the extend power switch terminal block (screwless spring clamp). Press the button, insert stripped wires (ground and SW+), then release. The PS_ON signal indicates power status (low = on).

4. Function Introduction

4.1 Terminal Block - Extend power switch

Extend power switch at rear IO of DEX5900 can allow customer to extend the power switch by their demand, and customer can decide their own switch specification and cable length just follow the wire gauge and strip length.

Ground & SW+ are for connection to extend power switch, and PS_ON is a signal to present the system power on/off status, when PS_ON signal is low, then system is in power on status when PS_ON signal is high, then system is in power off status

This is a screwless type spring clamp pluggable terminal block, you can insert a wire by press the button on the terminal, please refer to the procedure below.

Step 1 please prepare a pin or rod that hard enough for pushing the button on the terminal block Step 2 push the button in the end and hold it

Step 3 insert the wire into the hole and make sure the stripped portion is fully inserted Step 4 release the pin or rod then the wire will clamp by the terminal block
