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.
4.15.2.6. REMOTE ACCESS BY MODEM
The T360 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 API 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 T360 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 4.11.5). Once this is completed, the appropriate setup command line
for
y
our 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.
