The E3013 Serial Byte Monitor is a standalone module ideal for verifying serial data at common baud rates. Data is displayed as two large 0.56″ high hexadecimal numbers. This display is useful for single stepping serial data without a PC. There are 16 baud rates between 1.2K to 921.6K organized into four baud groups of four specific baud rates. On power up the baud group is set, and following this the specific baud rate can set using the switch settings. Power input is +3.3V to +5.5V and the outputs are TTL or 3.3V logic compatible.
