RS-232/RS-422 Communication

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.

The Status value is a bit field that has the following format:

Bit	Status Field	Convention
0	Laser @ Temperature	Yes=1 / No=0
1	Laser Interlock Open/Closed	Closed=1 / Open=0
2	Shutter Open/Closed	Open=1 / Closed = 0
3	Material Present	Yes=1 / No=0
4	Valid Measurement	Yes=1 / No=0
5	System Ready (Indicates Interlock	Yes=1 / No=0
	Closed, Shutter Open, and Laser @
	Temperature)
