ChannelSync Mainframe Hub
The CMH-20 ChannelSync Mainframe Hub provides a simple and effective
means to expand a LabMaster system beyond 20 channels (5 Acquisition
Modules). This is accomplished without any degradation of the timing
accuracy specifications. The Mainframe Hub is populated with cards for
each acquisition module (the back panel of the CMH-20 shown below is
populated with 20 cards for use with 20 Acquisition Modules, or 80 total
channels).
Connect a PCIe 1 Lane cable from the MCM-Zi Channel 1-4 output to the
single PCIe 1 Lane input at the lower right of the CMH-20 back panel.
Connect four PCle 4 Lane cables from the MCM-Zi data outputs for
channels 1-4, 5-8, 9-12, and 13-16 to the four PCIe 4 Lane data inputs along
the bottom of the CMH-20 back panel (to the left of the PCLe 1 input).
Connect from the PCIe 1 Lane Control, PCIe 4 Lane Data, and 10 GHz
ChannelSync Clock outputs to the corresponding inputs on the Acquisition
Modules.
