BackgroundThe USB TTL event marking module configuration utility lets you check both TTL Input and Output. In this example Output Line 1 has been sent high with a hex Output Port value of 01 and the appropriate red LED has illuminated (D pin 2). In addition the red output LED on the Module itself will also illuminate.
To send a given TTL Output Line high (+5V) click on it. To send it low (0V) click on it again so that the LED is not illuminated. Two byte hex Output values can range from 00~FF (hex), 0~255 (dec), 00000000~11111111 (bin) to represent the status of each Output Line on the Output Port.
Full step-by-step instructions are provided within the configuration utility. Depending on your antivirus package you may need to disable it while configuring your response device.
This configuration utility only works on Microsoft Windows platforms.
USB TTL event marking module drivers
The USB TTL module uses a Future Technology Devices International FT232R interface chip which must have drivers installed and configured correctly for it to operate. This is detailed in the USB TTL event marking module configuration utility manual. Drivers are included with the configuration utility, but if you wish you can download them directly from the FTDI website.
