The Serial Tap is an affordable sniffer for monitoring RS232, RS485, and TTL-level UART communications. The sniffer taps into the data and control lines of serial links and sends the recorded data to IO Ninja software in real time.
All inputs of the serial tap are available on a quick-release terminal block. The Tap also features two DB9 connectors for "wedge" monitoring of RS232 communications. The board even provides jumpers for swapping and loopbacking RS232 signals, and also sports bi-color LEDs for RS232 line status indication. The jumpers and bi-color LEDs give the Tap additional use as a simple tool for debugging RS232 wiring issues.
The Serial Tap must be used with the Serial Tap plugin of IO Ninja software.
