DT Research DT133: Hardware 


 


 

 



DT Research DT133 Thin Client

Like the DT166 the DT133 is small and compact. I do not know when it was launched, but the Basic Operation Guide for it was created in January 2011. The chipset it uses is the same as the Acer AspireRevo and the Tadpole Pulsar.

A distinctive feature is that it has a large external finned heatsink that is on the bottom of its case.

Power Supply

The DT133 requires an external 19V power supply. On the case it reads "19V 2.36A". The coax plug needed is 4.8mm/1.7mm. I used an old 18.5V laptop PSU that I had to hand.

CMOS Battery

The battery for the CMOS memory is one on a flying lead and so is not as cheap as some should you need to replace it.

Disassembly

Top of DT133 In the centre of the top of the unit is a plate that's held by four screws. Remove this to gain access to the main circuit board.

You can see from the photo that my DT133 has been rebadged by SUMO.

Expansion

Flash: The Flash memory in the DT133 is a SATA SSD and plugs into a socket on the end of a cable rather than a socket on the board. My DT133 came without an SSD, the SATA cable was just lying loose within the case. (Mouse over the photo right to see). The only mounting point I can see within the housing is a single pillar for securing a mPCIe card. I have no idea of the size/shape of the SSD and how it might be mounted.

RAM: The RAM is a single DDR2 SODIMM. I've fitted a 2GB PC2-6400S part that worked perfectly. (part HYS64T256020EDL-2). The data sheet I have says nothing about the memory other than '2GB'. Whether a 4GB part will work I have no idea. However a quick check on eBay shows that you could probably buy a number of better thin clients for the price of a single 4GB DDR2 memory part. (It explains why I have none in my spares box).

USB: There is a 4-pin JST connector on the board labelled JUSB3. I have done nothing with this.

mPCIe: There is a mPCIe connector on the board. I tried out an Atheros AR5BXB63 which was not recognised, but an Atheros AR5B91 was. The mounting pillar is sited for the longer (50mm) card. If you fit a half-size card you'll have to be a bit inventive to secure it in place.
