3.2 RS-232 SERIAL INPUT

The VSI-Pro Max accepts serial data via the DB-9 Female connector located on the rear of VSI-Pro Max. 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 Max RS-232 female connector. On the other hand Table 2 compares the VSI-Pro Max RS-232
with standard "AT" computer's RS-232 connector.
