APPENDIX A. STREAMING MODE OF SERIAL OUTPUT 

LID-3300IP  reports  the  measurement  data  and  status  in  the  serial 
output  as  explained  before  in  chapter  4.2.  This  chapter  explains  the 
formats in more detail. 

There  are  three  different  output  formats.  The  format  can  be  read  by 
command 

RSFORMAT

. 

Format 0: variable length 

 

Command 

RSFORMAT 0

 sets the variable length format. 

The output format consists of the following information: 

 

 

The different fields are delimited with a space character. Fail and Mode 
characters have no space between them. Negative temperature values 
have a ‘-‘-sign in front of the value, positive values do not. Ice signal 
amplitude has an asterisk (*) in front of the value. 

- 

Example (one temperature sensor):  

0F 15.0 *68

 

No  fail,  Mode:  detecting,  ice  sensed,  heating  on,  Sensor 
temperature 15.0°C, ice signal amplitude 68. 

- 

Example (two temperature sensors):  

0F 15.0 -5.0 *68

 

No  fail,  Mode:  detecting,  ice  sensed,  heating  on,  Sensor 
temperature  15.0°C,  ambient  temperature  -5.0°C,  ice  signal 
amplitude 68. 

Format 1: constant length 

 

Command 

RSFORMAT 1

 sets the constant length format. 

The output format consists of the following information: 

 

 

 
The different fields are delimited with a space character. Fail and Mode 
characters have no space between them. Temperature values start with 
zeros and have a 

‘+‘ or ‘-‘ sign in front of the value. Ice signal amplitude 

has an asterisk (*) in front of the value. The checksum consist of ASCII 
coded hex ‘ 0…F’ and is calculated from all preceding bytes (including 
space characters) by adding them together. 

- 

Example (one temperature sensor): 

 

0F +015.0 ----.- *068 1 04B8 

No  fail,  Mode:  detecting,  ice  sensed,  heating  on,  Sensor 
temperature 15.0°C, ice signal amplitude 68, rsformat 1, checksum 
04B8. 

- 

Example (two temperature sensors): 

0F +015.0 -005.0 *068 1 04C9

 

No  fail,  Mode:  detecting,  ice  sensed,  heating  on,  Sensor 
temperature  15.0°C,  ambient  temperature  -5.0°C,  ice  signal 
amplitude 68, rsformat 1, checksum 04C9.
