3.7 RS-232 and RS-485 Settings
Once the jumpers are set for RS-232 operation a terminal
program such as Hyperterminal can be used to change factory
default or existing settings. The following settings apply to
Hyperterminal or any other program that is used for
communications.
BAUD Rate Current SR50A Setting
Note
Data Bits 8
Parity
None
Stop Bits 1
Flow Control None
Note
The factory default BAUD rate is 9600 BAUD. Once
the BAUD rate is changed the new BAUD rate must be used
for further communications to the SR50A. It is important to
keep track of the BAUD rate setting on the SR50A. If the
BAUD rate setting is unknown, we recommend trying the
default value of 9600 BAUD. If that does not work, start at
BAUD rate 1200 and go through all the BAUD rate settings
until the correct one is found.
