is a carriage return / line feed pair, which terminates the message.
The uniform nature of the output messages makes it easy for a host computer to parse them into
an easy structure. Keep in mind that the front panel display does not give any information on the
time a message was issued, hence it is useful to log such messages for trouble-shooting and
reference purposes. Terminal emulation programs such as HyperTerminal can capture these
messages to text files for later review.
6.12.2.6. Remote Access by Modem
The M6200E can be connected to a modem for remote access. This requires a cable between the
analyzer’s COM port and the modem, typically a DB-9F to DB-25M cable (available from Teledyne
Analytical Instruments with part number WR0000024).
Once the cable has been connected, check to make sure the DTE-DCE is in the correct position.
Also make sure the M6200E COM port is set for a baud rate that is compatible with the modem,
which needs to operate with an 8-bit word length with one stop bit.
The first step is to turn on the MODEM ENABLE communication mode (Mode 64, Section 6.10.8).
Once this is completed, the appropriate setup command line for your modem can be entered into
the analyzer. The default setting for this feature is
AT Y0 &D0 &H0 &I0 S0=2 &B0 &N6 &M0 E0 Q1 &W0
This string can be altered to match your modem’s initialization and can be up to 100 characters
long.
