RS232
The RS232 connection is a standard DB9-F connection for serial communications to a PC or other
device. The RS232 port has a default baud rate of 9,600 (No parity, 8 data bits, 1 stop bit, HW
flow control) but other baud rates are supported. The primary use of the RS232 port is for
connecting to a PC for setup, maintenance, and troubleshooting. The PC will typically run
LinkComm software which will allow the user complete control over Satlink subject to the
password protection in Satlink.
The RS232 port also allows the connection of Sutron’s 8310, 9210 and Xpert loggers to Satlink.
With this connection, the Sutron logger can use Satlink as transmitter to send data that it
collects, rather than have Satlink collect the data. This is normally done where the field station is
very complex and the user desires the advanced capabilities of 8310, 9310, Xpert for the
collection and processing of the data.

The primary use of the connection is to allow the PC to setup, maintain and troubleshoot Satlink.
The PC will typically run LinkComm software which will allow the user complete control over
Satlink subject to the password protection in Satlink.
