# FLIR/DirectedPerception PTU Rotor Module
|
||
|
|
|
||
|
|
This module interfaces FLIR and DirectedPerception
|
||
|
|
rotor using the PTU protocol via serial.
|
||
|
|
|
||
|
|
This includes:
|
||
|
|
|
||
|
|
* PTU-D48(E)
|
||
|
|
* PTU-E46
|
||
|
|
* PTU-D100(E)
|
||
|
|
* PTU-D300(E)
|
||
|
|
|
||
|
|
Tested only with PTU-D48 yet and with one rotor per chain only.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
1. Connect the rotor via serial (RS232 or RS485)
|
||
|
|
2. Power up the rotor
|
||
|
|
3. The rotor must be calibrated after each power up. This can be accived
|
||
|
|
either using the rotctl `Reset` command (R) or manually via serial terminal
|
||
|
|
sending the `R\n` command.
|
||
|
|
4. To enable the rotor to fully turn +/- 180°, the softlock must be disabled.
|
||
|
|
This is included in the rotctl `Reset` commnad or manually via serial terminal
|
||
|
|
seinden the command `LD\n`. **WARNING:** Send this command only after the rotor is
|
||
|
|
calibrated, or you risk damage running into the hard endstops (at about +/-190°)
|
||
|
|
5. Start `rotctl` or `rotctld` with the arguments `-m 2501 -r <Serial
|
||
|
|
Interface>`
|
||
|
|
|
||
|
|
Have Fun.
|
||
|
|
|
||
|
|
### Hints
|
||
|
|
|
||
|
|
1. Setup the max. velocity, power and acceleration according to your antenna load.
|
||
|
|
This must be done via serial terminal, as the functions are not implemented yet.
|
||
|
|
2. Never use the maximum hold power, only use the low or off. If you use max or regular,
|
||
|
|
the rotor may easily overheat!
|
||
|
|
|
||
|
|
## PTU Protocol
|
||
|
|
|
||
|
|
* [Protocol Version 3.02 (2011)](https://flir.netx.net/file/asset/11556/original/attachment)
|
||
|
|
|
||
|
|
## Current Status
|
||
|
|
|
||
|
|
The current status is **ALPHA**. It is tested with DirectedPercepiton PTU-D48 (Firmware v2.13.4r0(D48-C14/E))
|
||
|
|
Linux with `rotctl` and `gpredict`.
|
||
|
|
|
||
|
