Table 1: Pin-Out of the DB-9 Female Connector on the VSI-Pro RS-232

3.1 RS-232 SERIAL INPUT

The VSI-Pro accepts serial data via the DB-9 female connector located on the rear of VSI-Pro. This connector is similar to “AT” type computer RS232 serial ports and the pin out is identical. Table 1 shows the standard pin out for VSI-Pro RS-232 female connector. On the other hand Table 2 compares the VSI-Pro RS-232 with standard “AT” computer’s RS-232 connector.
