CMX34KB cpuModules
RTD'sCMX34KBcpuModulerepresentsthe latestin high performance PCIe/104embedded controllers with
a Type 2 bus. Thisdesign isbasedon an Intel® Kaby Lake Xeon processor with CM238 Platform Controller
Hub. The CMX34KBis offered with either a 2.2Ghz Quad-Core processor ora 3GHz Quad-Coreprocessor.
Gen 3.0 PCIe support consists of 8 PCIe x1 lanes and 4 PCIe x4 lanes. The top PCIe bus connector contains
4 x1 lanes and 2 x4 lanes. The bottom connector also contains 4 x1 lanes and 2 x4 lanes.
Onboard memory consists of 16 GB of embedded ECC DDR4 DRAM with a speed of 2400 MT/s (1200
MHz).
The cpuModule’s DisplayPort video interface supports audio and a maximum resolution of 4096 x 2304.
A Serial-ATA (SATA) controller provides six SATA 3.0 links. Two links to the top and two links to the
bottom PCIe connectors. One of the remaining two links is routed to an embedded 60 GB drive and the last
link is routed to an onboard SATA connector.
A xHCI controller supplies a USB 3.0 connection, with up to 625 MB/sec data throughput, to a USB A
connector. The controller also supplies 5 USB 2.0 connections. Four connections are routed to 10 pin
connectors and the last one is utilized in the Utility port for the use of a keyboard and mouse.
Network connectivity is provided by two 10/100/1000 Mbps Intel®i210 Ethernet controllers.
Other features include RS-232/422/485 COM ports and Advanced Digital I/O (aDIO).
RTD has implemented additional features for increased utility and security. These includeRS-232/422/485
COM ports, Advanced Digital I/O (aDIO), an Advanced Watchdog Timer and a Trusted Platform Module
(TPM 2.0). The CMX34KB is also madeavailable in a rugged and fan-less IDAN enclosure.

BDM-610000090 Rev A CMX34KB User’s Manual 13
You can easily customize the cpuModule by stacking PCI/104-Express or PCIe/104 modules such as video
controllers, Digital Signal Processors, drive carriers, LAN controllers, or analog and digital data acquisition
modules. Stacking modules onto the cpuModule avoids expensive installations of backplanes and card
cages and preserves the module's compactness.
The cpuModule uses the RTD Enhanced BIOS. Functionality in the BIOS allows booting from hard disk,
UEFIshell, USB, or network booting.
The cpuModule and BIOS are compatible with any real-time operating systems for PC compatible
computers, although these may require creation of custom drivers to use the aDIO and watchdog timer.
aDIO
RTD’s exclusive aDIO™ is 12 digital bits configured as 8 bit-direction programmable and 4-bit
port-direction programmable I/O, plus 2 strobe inputs giving you any combination of inputs and outputs.
Match, event, and strobe interrupt modes mean no more wasting valuable processor time polling digital
inputs. Interrupts are generated when the 8 bit-direction programmable digital inputs match a pattern or on
any value change event. Bit masking allows selecting any subgroup of eight bits. The strobe input latches
data into the bit-programmable port and generates an interrupt.

BDM-610000090 Rev A CMX34KB User’s Manual 14
Ordering Information
The CMX34KB cpuModule is available with a selection of processors and heatsinks. The cpuModule can
also be purchased as part of an Intelligent Data Acquisition Node (IDAN™) building block, which consists
ofthe cpuModule and a milled aluminum IDAN frame. The IDAN building block can be used in just about
any combination with other IDAN building blocks to create a simple but rugged PC/104 stack. Refer to
Appendix C, IDAN™ Dimensions and Pinout, for more information. The CMX34KB cpuModule can also
be purchased as part of a custom-built RTD HiDAN™ or HiDANplus High Reliability Intelligent Data
Acquisition Node. Contact RTD for more information on its high reliability PC/104 systems.
CMX34KB Model Options
The basic cpuModule model options are shown below. Refer to the RTD website (www.rtd.com) for more
detailed ordering information and any new variations that may be available.
