April 22, 2009 - SMH Technologies unveils today the new signal multiplexer for device in-system programming (MicroPlexer). Microplexer allows the ISP connection coming from the programmer/tester to be switched to one of the available output channels. In this way, a single programmer/tester can easily handle multiple device programming, whether on a single board or distributed across multiple boards in a panel assembly.

MicroPlexer is designed for the typical scenario in which a multi-PCB panel needs to be in-system programmed, saving the costs and hassles of designing and building an in-house, ad-hoc solution.

The MicroPlexer main features are:

• Switching of 160 signals;
• Easy integration with all ATE systems;
• Multiplexing through FET and Reed relay;
• Controllable by a host PC or ATE through RS-232 or parallel control lines;
• Compact size.

MicroPlexer is controlled via either ASCII-based commands (through its RS-232 channel) or via control lines. ASCII commands allow for selecting the output channel or to disconnect all of the output channels.
