The EXC-4500ccVPX/xx conduction cooled card for VPX compatible computers, supports up to two dual redundant MIL-STD-1760 channels using the M4K1553Px(S)-1760 module and is compatible with all common variations of MIL-STD-1760 (A, B). In addition, Checksum, SRQ bit and Header Words are supported on each channel. 
Multi Function:
Each channel using the M4K1553Px-1760 module operates simultaneously as a Bus controller and/or multiple (up to 32) Remote Terminals, or as a Triggerable Bus Monitor. In addition, error injection (BC and RT modes) and error detection (all modes) are supported on each channel. 
Single Function:
Each channel using the M4K1553PxS-1760 (RT validated) module operates either as a Bus Controller, Remote Terminal, or Bus Monitor.
The EXC-4500ccVPX/xx is supplied with C drivers, including source code, Merlin+ Windows software and  may be used with Exalt, Excalibur’s Analysis and Laboratory Tools, a Windows monitoring application. Mating connector provided for I/O connection.
Please see multi protocol 4000 modules for additional information on protocols that can be added to this card.
