9.6 Compatibility with THQ 1.xx
The instruction set was simplified with Version 2.00. It is recommended to use the new instruction set for communication with
the device. However, it is possible to emulate the behavior of THQ firmware 1.xx. To do so, the command E1=2 has to be sent to
the device. If the device has more than one channel, the command has to be executed for every channel.
The following differences apply in compatibility mode:
•
For every answer, the command is repeatet first
•
The current limit is transmitted in mA (for I
nom
≥ 1 mA) respectively in µA (for I
nom
< 1 mA).
