The UC-7122/7124 Series of mini size RISC-based ready-to-run 
embedded computers come with the WinCE operating system 
pre-installed. The embedded computers have dual 10/100 Mbps 
Ethernet ports and 2 or 4 RS-232/422/485 serial ports in an ARM9 box. 
In addition, the UC-7122 and UC-7124 have an internal SD socket and 
one USB 2.0 host port for storage expansion, to provide high 
performance communication and unlimited storage in a super compact, 
palm-size box. The UC-7122 and UC-7124 are the right solutions for 
embedded applications that use a lot of memory, but that must be 
housed in a small physical space without sacrificing performance.

4. Installing the UC-7122/7124 

The UC-7122/7124 have built-in “ears” for attaching 
the embedded computers to a wall or the inside of a 
cabinet. We suggest using two screws per ear to 
attach the UC-7122/7124 to a wall or cabinet. The 
heads of the screws should be less than 6.0 mm in 
diameter, and the shafts should be less than 3.5 mm 
in diameter, as shown by the figure at the right. 

6.0 mm

3.5 mm

 

 

DIN-rail attachments can be purchased separately to attach the product to 
a DIN-rail.
