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
settings:
9600 Baud, 8 data bits, Parity =None, 1 stop bit, Flow control =None
After the Hyper terminal Program is running and its window is opened, enter the text
string >HELP (or >?) followed by carriage return to display available commands for
the TL6.5. The convention used is command {parameter} or command [parameter],
with {} meaning required parameters and [] meaning optional parameters. For systems
without a return button the amplifier’s microprocessor recognizes /C as a carriage
return, and /R as a return. The input and output buffers of the TL6.5 can hold a
maximum of 256 bytes at one time.
The available RS-232 user commands are:
