Terminal mode allows a user to interactwith the 2010D using a remote terminal. Command mode allowsanother computer or datalogger to control and monitor the 2010Dusing a command protocol. Both operating modes may be used onthe same serial port, however the correct mode of operation mustbe selected first.
