RC4 cryptography method
In RC4 cryptography mode, the Model 2285 encrypt and decrypt all TCP streams using a Key string. The
Model 2285 can communicate with another device or another Model 2285 that supports RC4 cryptography
mode with same Key string.
For the sample application programs of SSL/RC4 cryptography method, please contact the Patton Technical
support.
Serial port parameters
To connect the serial device to the Model 2285 serial port, the serial port parameters of the Model 2285 should
match exactly to that of the serial device attached. The serial port parameters are required to match this serial
communication. The parameters required for the serial communication are: UART type, baud rate, data bits,
parity, stop bits, flow control DTR/DSR behavior and inter-character timeout.

UART type
: First of all, the Model 2285 and the serial device must agree on the serial communication type,
which is one of RS232 mode, RS422(RS485 full) mode or RS485 half mode. User can set the serial com-
