2.2 Communications
2.2.1 RS-232 Communications and DB-9 Connector pinout
A standard DB-9F is provided for RS-232 communications. Power may also be supplied via this con-
nector if desired. In addition, the user may use the two middle pins of the power connector for serial
communications. The RS-232 connector on the serial cable is wired so that a standard straight through’, 9
pin D-sub cable may be used to connect the modules to a standard serial port such as COM ports on PCs.
Note that this device complies with the EIA232 standard in that it uses signal levels from ±12V to ±12V. It
can also operate correctly at TTL (0 to +5V) levels. To use standard RS-232 no modifications are required.
For TTL, please refer to the Table below.
