Wyse Cx0: Hardware 

Wyse Cx0


The Wyse CX0 is very similar in appearance to the Sx0 that it replaces. It is a small and (physically) lightweight thin client. In contrast to the Sx0 it has two PS/2 ports and no serial port - a reversal in policy here! There are two USB ports at the front and two USB ports on the rear. The video connector is a DVI socket. With a suitable splitter the Cx0 will support two independent monitors.

A Quick-Start guide I found mentions the following models: C00LE, C10LE, C30LE, C50LE, C90LE, C90LE7, C90LEW, but a C-Class data sheet mentions only five:

Wyse C00LE Zero client with no local operating system. Used with Wyse WSM provisioning software for a PC experience on a thin desktop.
Wyse C10LE Featuring the blisteringly fast Wyse ThinOS designed for high security environments.
Wyse C30LE Windows CE 6 - Microsoft's componentized real-time operating system for small footprint devices.
Wyse C90LE Windows XP Embedded - runs thousands of existing Windows applications and drivers.
Wyse C90LEW Take advantage of the power of Microsoft Windows Embedded Standard.

I have several examples of the Cx0:

  1. A few C90LEWs manufactured in March 2010 fitted with wireless cards.
  2. A C90LEW manufactured in November 2011.
  3. A C10LE manufactured in February 2013.


The basic specs for the CX0 are:

Power Supply

The unit uses a small external power unit rated at 12V @2.5A. It's fitted with the usual 5.5mm/2.1mm coaxial plug.


Flash: The flash is a Disk-On-Module that plugs into a standard 44-pin IDE socket.

RAM: The RAM is provided by a standard DDR2 200-pin SO-DIMM. The C10LE was fitted with a 512MB PC2-6400 CL5 Apacer part whist the C90LEW was fitted with a 1GB PC2-6400 CL6 Apacer part. I have successfully replaced the RAM with a 2GB Hynix part HYMP125S64CP8-S6 (2GB 2Rx8 PC2-6400S-666-12). I don't know what the maximum size of memory is that the hardware supports.

As with the Sx0 range there is minimal space inside for fitting any alternative to the standard DOM.

As usual click on the photo for a larger version.


There are several (white) connectors on the board:

CN2 close to the front panel adjacent to the USB sockets. This has 10 pins.

CN3. A 3-pin connector next to the SODIMM socket with a shorting link connecting two of the pins together. Briefly move the shorting link across to the end closest to the front panel to reset the CMOS.

CN10. A 4-pin socket next to the board mounting screw, now known to be a USB port.

CN11. A 6-pin socket next to CN10. This is a USB port that the internal wireless card plugs into (if fitted). I now have a few C90LEWs with the card fitted.


Wyse CX0 wireless card

In February 2017 I picked up some C90LEWs with wireless cards fitted. The card fits into the space between the DOM and the copper heatsink and SODIMM. It plugs into CN11 and appears on the USB bus where it is identified as Ralink Technology Corp. RT2770 Wireless Adapter.

Under 'Networking' the datasheet does mention:

Cisco CCX Certified internal 802.11 b/g/n (optional) eliminates theft of external wireless adapters

The board itself would appear to be a QCOM LR802UKN unit that is an 802.11b/g/n module working in the 2.4GHz band.

Standard USB connections run to four wires. I have no idea what the additional two wires are there for.

Wyse CX0 wireless card

In December 2023 I heard from Michael who had added WiFi to his Cx0. He had sourced a WLAN module M-RTL8188ETV/5, removed CN11 from the motherboard and soldered the module direct to the board.

It's one way of avoiding having to source the right connector and the four stiff wires he used do provide a good support for the WLAN board.

Internal USB

Originally I listed the Cx0 as having four USB ports - the four external ones that you can see. Subsequently I receive an email from Janusz in Poland saying that Windows reports six USB ports and that there were two additional internal ones. One of these is CN11 which is used for the wireless network card, the other is CN10.

Wyse CX0 USB test setup
In September 2022 I checked out CN10. CN10 is a JST socket with 1.25mm pin spacing. Luckily I had a pack of ready wired plugs with flying leads to hand. My multimeter showed me the pin next to the arrow was +5V. This corresponded to the red wire on the plug. My proof of concept lash up is shown in the photo. I soldered the flying leads to a standard 0.1" strip line connector in the same order that they came out of the plug. I then plugged in a USB socket that was wired with a socket designed to plug into the headers on (what are now old) motherboards. (See the Neoware CA15 entry for the pin out of these connectors). You just have to make sure that the end with the red wire connects to the +5V pin coming from the Cx0. (Also a red wire with the connectors I was using).

Wyse CX0 internal USB connectors
I guess if you want to add some internal permanent USB storage you could solder the flying leads direct to a dismantled USB pen drive. That way you stand some chance of fitting it in the limited internal space.

I tried it out on old 1GB flash drive and it works. Just need to add an outer covering of heatshrink....

Wyse CX0 internal USB connectors
The two internal USB connectors. CN11 is wired to a Wireless card. I haven't checked the pin spacing or the connections on that plug. CN10 with a 4-way JST 1.25mm plug connected to my test USB setup.
