I need to use a CSE-H20 device to receive a code via RS232 from an RFID scanner. This is the correct working function. Second function , which I need, is DTR signal. From Host I send to CSE-H20 "DTR active" state. When I use USB/RS232 converter - function work properly.
When I use CSE-H25 with telnet - function work properly.
When I use CSE-H20, this function didn't work.
