RS232 to TTL/CMOS Converter
1. Use static electricity discharge precautions.
Remove possible static discharge potential from any objects that the
converter may come in contact with before installation. This can be
accomplished by touching a bare metal chassis rail after you have
turned off the power.
2. Locate an unused PC's RS232 port (with DB9 male connector, configured
as DTE), connect it to this Converter's DB9 female connector, connect the
TTL/CMOS RS232 Device to the Converter's DB9 male connector (with a
cable) .
