The preamplifier also communicates via the RS-232 port any changes made via the
front panel or remote wand, using what is called ‘event generation’, to keep other
connected components in synch with the TL-5.5.
Control functions and information returned are accessed through the rear RS-232 port
via a standard DB9 male female connector cable and standard ASCII text strings using
pre-defined commands as listed below in the summary of all the control functions that
can be performed on the front panel and the expected results on the RS-232 port.
The RS232 communication port is designed to interface with central command
systems to enable the preamplifier to be located and operated remotely, and allows the
user to interface with the preamplifier using any PC and the standard HyperTerminal
utility provided with the Microsoft Windows Operating system. Hyperterminal is
configured using the Properties command under the File menu with the following
