Praim Compact Dual Core Series: Hardware 


 


 

 



Priam Compact Dual Core Series thin client

Praim Compact Dual Core Series label This Praim thin client is a neat unit. The pull out label identifies it as a c22 model which doesn't align with any official datasheets. However on the Praim Website in the FAQs there is a passing mention in a FAQ to do with a Honeywell barcode reader being incompatible with the Compact devices. There we find the words:

...Praim Compact Dual Core (Cxxxx) devices. This devices are also identified with Praim C22 harwaremodel.

Praim Compact Dual Core Series Clientron L700 label Handily there is a label on the motherboard under the RAM which shows it is a L700 which is actually manufactured by Clientron. I did locate a datasheet for both the L700 and the Praim Compact Dual Core Series. The Praim range are numbered C9XXX, with the different model numbers covering the different configurations of flash, RAM and OS.

The datasheet for the range is V1.12 dated March 2016.

Disassembly

This is straightforward and is the same as described for the 10ZiG 58xx.

Power Supply

The unit requires a 12V supply and uses a conventional 5.5mm/2.1mm coax connector.

Expansion

Praim Compact Dual Core Circuit Board As usual, clicking on the photo (right) will take you to a larger scale photos of the circuit board.

The case is fairly compact in size so there is little space to fit anything internally.

Flash: The Flash memory is replaceable. It's a DOM plugged into a 22-pin SATA connector connector. The disassembly instructions show you how to access it. The Vx900 data I have seen just refers to two 'SATA ports' so I assume they must be SATA 1 ports. There is nothing in the BIOS for configuring the ports and, looking in the dmesg output, the port appears to be mapped as an IDE port.

....
ata1: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xfc00 irq 14
ata2: DUMMY
....
ata1.00: ATA-8: KingSpec KSM-HS.5-002SJ, 120202, max UDMA/133
ata1.00: 3928176 sectors, multi 16: LBA48 NCQ (depth 0/32)
ata1.00: limited to UDMA/33 due to 40-wire cable
ata1.00: configured for UDMA/33

RAM: The RAM is a conventional DDR3 SODIMM plugged into a socket fitted on the top of the board. The fitted 204-pin SODIMM was a 1GB Transcend part 656657-0396. This is a DDR3 1333 part. I also tried out a 4GB part (4GB 2Rx8 PC3-10600S-9-10-F2) from Elpida that worked.

USB: There are two USB sockets on the front panel, two on the rear, and one in a concealed panel on the top of the unit. These are all USB 2.0 ports.

Mini PCI: There is an internal mini PCI socket where you could fit a wireless card. You can see from the photos below that it's not the easiest to access.

SATA: There is another on-board SATA socket with a power socket next to it. The pin furthest from the SATA socket carries +5V.

Priam Compact Series mini pcie connector
The Mini PCIe connector on the left. This at the top and partially under the side panel. Just about visible bottom left is a white connector with red/black wires. These come from the heat-shrink wrapped backup battery that sits underneath the motherboard - more disassembly work is required if you ever have to change it.

On the right you have the second SATA socket with a two-pin socket next to it. This has +5V on the pin furthest from the SATA socket. Beyond that is a small four-pin socket whose purpose I don't know.
