Data Format
The Data Format field selects the word length and number of stop bits for the data stream. The following
options are available*:
a. 8 Data Bits, 1 Stop Bit
b. 8 Data Bits, 2 Stop Bits
c. 9 Data Bits, 1 Stop Bit
d. 9 Data Bits, 2 Stop Bits
Table 2-8 shows supported user formats and modem programming.
Note: A Yes in the Parity column indicates Even/Odd or Mark/Space Parity. A No in the Parity column
indicates none. N/A means the combination is not available.
