CM10TB TEST & REFERENCE BOARD
UNAGI
NET L L C
Checking the data
When power is ?rst applied, the test board will output 32 ASCII bytes (00 to 1F) as a reference label.
Make sure your terminal program properly displays these bytes on the screen. If you see garbled data,
verify that the communication protocol is properly set to 57,600/8-N-1 (57.6Kbaud; 8 data bits; No
parity bit; 1 stop bit) and cycle the power.
Press the Return key <CR> on the keyboard and the terminal display will show the values of the
CM1015 registers 00 to 1F. Every time a Carriage Return <CR> is sent to the test board, the test
board will return all 32 bytes of the test CM module’s data registers.
The data output over the serial port is ASCII formatted. This means that the data is formatted for
proper display with a terminal program. If the data is to be used for control purposes, then it would be
advisable to convert the ASCII data to HEX for easier correlation to the CM10xx datasheet register
values.
At the end of each 32 byte packet of register data, a Return <CR> and a Line Feed <LF> command is
sent. This properly formats the register data on the terminal display.
For descriptions and explanations of the CM module’s 32 byte data packet, please refer to the CM1015
datasheet.
