E - CONFIGURATION
The
frametype
parameter determines the format of the telemetry frame.
When modifying this parameter with the “
set
” command, you must enter
“
binary
”, “
short
”, or “
long
” as the value parameter. Please refer to the
Telemetry Format section.

Command Line Parameter:
telbaud
The telemetry baud rate defines the speed at which data is transferred on the
telemetry interface. This should not be confused with the frame rate. Baud rates
are specified in units of
bits per second
(bps). Any data acquisition or terminal
emulation software must be configured to communicate with the instrument at
this baud rate. Only certain standard parameter values are accepted, as shown
in the table below:
Baud Rate (bps)
9600
19200
38400
57600
115200
When modifying this parameter with the “
set
” command, you must enter at
least the first two digits of one of these baud rates as the value parameter.
Ideally, you would want the telemetry interface to run at the fastest baud rate
available. However, certain restrictions, like cable quality or excessively long
transmission mediums, may require a reduction in the telemetry baud rate. The
data acquisition computer and/or software may also impose restrictions.

Command Line Parameter:
maxrate
This parameter allows you to define the maximum frame rate that the
instrument will use during normal operation with free-running telemetry output.
The frame rate defines how often a frame of telemetry is composed and
transmitted. If the instrument is running autonomously (autonomous operation),
frames are transmitted through the telemetry interface. If the instrument is
operating in network mode (network operation), these frames are transmitted
through the network interface. However, the Network Master can be configured
to override the frame rates of all other instruments, imposing its own frame rate
on the system. See the operation manual of your Network Master device for
more information.
Frame rates are specified in units of
frames per second
or
Hertz
(Hz). There
are several factors involved in determining how quickly the instrument can
