TE Text Output Mode
TE<CR> Data Output Command
Data Format: <L,V,QF,ST><CR>
This command places the LS8000-3 into Text Output Mode. This mode only affects the
communication port over which the command is sent. For example, if the command is sent
over RS-232, only the RS-232 port will transmit measurement data—the RS-422 and
Ethernet ports will not change operation.
The LS8000-3 will output a serial message at an interval determined by the User Update
Rate (O setting). This rate can vary from 1ms to 2.047s. If using a fast update rate, it may
not be possible to transmit every reading at lower baud rates. Refer to the Real-Time Data
Timing Considerations section for details.
The measurement data is a comma delimited list of the current measurement data outputs.
The response string is always 28 characters. All fields are zero-padded to form a constant
length string.
