RTM-ComEx Overview

The RTM-COMEX is a 3U OpenVPX RTM Module for the VPX-COMEX CPU card. The RTM-COMEX provides I/O support for the VPX-COMEX including USB, Ethernet, DisplayPort and VPXI Timing Expansion.

Standard I/O features include four USB 2.0 ports, Gb Ethernet, and DisplayPort audio-video. The RTM_COMEX integrates 4 port USB hub supporting USB2.0 , with one rear panel port and three internal ports. A socketed for 25mm coin batteries connects to VPX P0 for system battery.

The RTM-COMEX has a timing expansion port for VPXI timing signals. The rear panel port provides clock and trigger to other VPXI systems or user equipment.. Timing clocks and signals are routed to the VPXI system timing controls so that multiple systems can run in synchronization and perform coordinated sampling. User-defined signals may be used for further customization.

The RTM-COMEX also has an interface to a GPS for communications, PPS and timing reference. A GPS unit can be integrated with the VPX-COMEX as a timing reference using the 10MHz and PPS signals from the GPS for clock reference and triggering. A UART interface in the VPX-COMEX, with supporting software, can use a Trimble Mini-T or Thunderbolt GPS.

The card requires a double-wide (8HP) slot.

Software tools for host development include C++ libraries and drivers for VxWorks, Windows and Linux. Application examples demonstrating features are provided for the VPX-COMEX.
