In addition, there are 8 digital input/output lines (which are inde- pendently programmable). The Check-MATE is made available in two versions, a standard model or with a USB option. The standard model is designed for embedded applications and provides a simple Oi-BUS interface for control by a external microcontroller. -

Ports) and verify “OI Serial Interface (COM#)” is included. The diagram below provides a basic illustration of a PC-driven configuration. As shown, the Check-MATE is used to stimulate a hybrid module in a test & meas- urement application. The hybrid module is a mix-signal device that requires Ana- log I/O, as well as Digital I/O to function properly. -

CHECK-MATE USER’S MANUAL 3.2.1 PC Programming The starting point for developing code to control the Check-MATE, begins with acquainting yourself with its Serial Command Set. The serial commands are a sequence of ASCII characters that originate from the PC and are designed to instruct the Check-MATE to perform specific functions. -

Download the panel from our website at www.check-mate.com, click on downloads and select “Check-Matexxx.exe”. Third Step: After initializing, the module Second Step: Push the Initialize should send back a unique ID code. -

All commands are upper case sensitive and are terminated with a carriage-return. If the command is valid, the Check-MATE will return either a ‘<>’, or a bracketed result (i.e. ‘<0F4>’. If the Check-MATE receives a carriage-return or line-feed alone (without a command), then a ‘ ’ is re- turned (this response is a “prompt”... - Page 20 CHECK-MATE USER’S MANUAL Appendix A.
