UDP
8.3.2 Interface Mode
The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation. Use the following table to select Interface Mode settings:
Table 23 - Interface Mode Options
I/F Mode Option | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
RS-232C (1) | | | | | | | 0 | 0 |
RS-422/485 (1) | | | | | | | 0 | 1 |
RS-485 2-wire (1) | | | | | | | 1 | 1 |
7 | Bit | | | | | 1 | 0 | | |
8 | Bit | | | | | 1 | 1 | | |
No Parity | | | 0 | 0 | | | | |
Even Parity | | | 1 | 1 | | | | |
Odd Parity | | | 0 | 1 | | | | |
1 | Stop bit | 0 | 1 | | | | | | |
2 | Stop bits | 1 | 1 | | | | | | |
(1) The UDS-10 requires you to choose the correct setting in the IF mode.
The following table demonstrates how to build some common Interface Mode settings:
Table 24 - Common Interface Mode Settings
Option | Binary | Hex |
RS-232C, 8-bit, No Parity, 1 stop bit (1) | 0100 1100 | 4C |
RS-232C, 7-bit, Even Parity, 1 stop bit (1) | 0111 1000 | 78 |
RS-485 2-Wire, 8-bit, No Parity, 1 stop bit (1) | 0100 1111 | 4F |
RS-422, 8-bit, Odd Parity, 2 stop bits (1) | 1101 1101 | DD |
(1)The UDS-10 requires you to choose the correct setting in the IF mode. Note: See Table 35 - Binary to Hexadecimal Conversion Table.
