Step 5: 10 MB File transfer at 3 Mbps, with no Data-Loss
• In the Tera Term window, go to
Setup > Serial Port
, enter 3000000 in baud rate box, and select
Hardware
in
Flow control
drop-down menu; go to
Setup > Terminal
> Receive
, select
CR+LF
• Connect TXD to RXD and CTS# to RTS#, with “Jumper Wires”
• Enable file capture: go to
File > Log;
uncheck
Append
and select <file name> to save the received data
• Go to
File > Send File
, select Test.txt file from <Install directory>\Cypress\CYUSBS232 RDK\1.0
• “Tera Term: Send file” window shows effective data throughput; multiply by 2X to get uni-directional
throughput. Actual throughput will be less than 3 Mbps, usually around 1 Mbps, due to protocol overhead
and PC Application latency
• Compare Test.txt and Received file, using file compare utilities to verify data integrity
