Introduction 1 Introduction Last update: 18SEP2018 Manual Update History This Manual covers IO Ninja-compatible hardware: · Serial Tap Other types of hardware sniffers will be available in the near future. Serial Tap IO NINJA Serial Tap is an affordable serial sniffer that can monitor RS232, RS485, and TTL-level UART communications. The Tap connects to your PC via a USB cable and is compatible with IO Ninja terminal/sniffer software for Windows.
2 IO Ninja Hardware Manual (NHM) · Has three operating modes: RS232, RS485 [N ote 2 ] , and UART (TTL [N ote 3 ] ), selectable via a slide switch. · All inputs are connected to an 18-position, quick-release terminal block.
Serial Tap 3 Note 3 "TTL" here means "digital signals of microcontrollers, microprocessors, and other ICs." TTL inputs of the Serial Tap are also compatible with CMOS circuitry. Most importantly, "TTL" serial signals are usually inverted with respect to RS232 signals: a LOW (negative voltage) on an RS232 line corresponds to a HIGH level on a serial TTL (CMOS) line, and HIGH (positive voltage) on an RS232 line corresponds to a LOW level on a serial TTL (CMOS) line.
4 IO Ninja Hardware Manual (NHM) Block Diagram Using the Serial Tap To start using the Serial Tap: · Install IO Ninja software (http://ioninja.com/). · On the Serial Tap, slide the mode selection switch into the desired position depending on what interface you will be using — RS485, RS232, or UART (TTL). · Connect into the corresponding group of terminals on the terminal block. When in the RS232 mode, you can also employ wedge RS232 monitoring method. · Plug the Serial Tap into the USB port of your PC.
Serial Tap 5 · Click on the Tap dropdown and select the Serial tap. Note: you can connect several Serial Taps to one PC. If necessary, refresh the list of available Taps. · Set the baudrate and click the Listen button to start the data acquisition. A note on the Serial Tap limitations Please note that the Tap monitors serial traffic through two independent serialover-USB channels. The first channel monitors TX, RTS, and DTR lines, while the second channel deals with RX, CTS, and DSR lines.
6 IO Ninja Hardware Manual (NHM) Of course, DB9 genders on the serial devices may differ from the above example, and so your serial arrangement may be different. To aid you in the "wedging process," each Serial Tap comes with two DB9 gender changers. Jumper pairs The Serial Tap has an additional useful feature allowing you to swap and loopback the signals in TX/RX, RTS/CTS, and DTR/DSR signal pairs. To achieve this, two jumpers are provided for each of the three pairs.
Serial Tap 7 Ordering and Specifications The Serial Tap is supplied with a USB cable and two DB9 gender changers.
