picoScan150 - Differences in software settings compared to TiMxxx

This tutorial shows the differences between the picoScan150 Core software settings compared to a TiMxxx.
In this case, we compare a picoScan150 Core (FW V1.0.2) and a TiM781 (FW 5.02). However, the information also applies to most other picoScan150 and TiM4/5/7 variants with the latest firmware. We'll go through different settings as in a real customer setting.

 

The goal is to:

• Login as Service
• use CoLa B
• use 15Hz of scanning frequency and 0.33° of angular resolution
• limit the device to a field of view of 185° forward facing
• only use the first echo
• set filter
• output distance and RSSI data
• output the data in LMDscandata format

TiM781

The default passwords are identical.

While Service is available with default settings the other user levels need to be activated before they can be used.

For the TiMxxx, the default ports (2111 and 2112) are always set to Cola A. For the picoScan150 these are different (see the picture above) and can not be changed with FW V1.0.2.

TiM781

The TIM uses 15Hz of scanning frequency and 0.33 ° of angular resolution as a default setting. This is not changeable.

The picoScan150 uses 15Hz of scanning frequency and 0.33°/1° of angular resolution as a default setting. This is changeable.

• As the coordinate system changed, you need to set different values to reach the same result with the picoScan150. The LMDscandata output format of the picoScan still uses the TiMs convention (-48° to 228°).
• For the picoScan150 the filter needs to be activated, this was not necessary with the TiMxxx.

The TiM781 does not have multi-echo technology. Hence, there is only one echo. To have the same behavior with the picoScan150 you need to activate the Echo filter and set it to either first or second echo. Otherwise, you get a lot more output data.

Filter	TiM781	picoScan150	Notes
Edge filter	yes	no
Median Filter	yes	no	on the road map
Moving average filter	yes	yes	-
Interval filter	yes	yes	-
Angle range filter	yes (named output data range)	yes	-
Particle filter	yes	yes	-
Fog Filter	no	yes	-
Echo Filter	no	yes	-
Cuboid area filter	no	yes	-
Distance filter	no	yes	-

TiM781

The TiM always outputs the distance data by default. The RSSI data, the device name and the timestamp can be activated if needed.

The TiM always outputs the data by default.

The default format is Compact. Therefore you need to set it to LMDscandata.

The picoScan150 outputs the RSSI data by default and can not be deactivated with FW V1.0.2. The picoScan150 does not output the device name and this timestamp

with FW V1.0.2. However, it outputs "Time since start-up in us" and "Time since transmission in us" at the corresponding position.

 

• The default format is Compact. Therefore you need to set it to LMDscandata.
•  
• The picoScan150 has a larger field of view. Therefore, there are an additional 54 bytes (18 beams * (2 bytes per distance value + 1 byte RSSI value))
• Due to the higher measurement range, distance values can reach up to 65m (65535 mm). With range extension mode the maximum distance is 120m and the scale factor in LMDscandata is set to 2 (maximum value in telegram: 65655)
• The picoScan150 does not output the device name and the timestamp with FW V1.0.2. If you activate these options in the TiM the output telegram gets longer and therefore the byte difference between picoScan150 and TiM gets less than 54 bytes.
