*1 These items can be set by software.
For the "Standard COM Driver Software COM Setup Disk" on the bundled disk, the range is 300 - 921,600 bps.
*2 Data transmission at high speed may not be performed normally depending on the environment including the type of
status of connected material of cable and environment.
*3 This depends on the PC environment used (OS and USB host controller).
*4 To suppress the heating, ensure that there are spaces for ventilation (about 5cm) around this product.
