ALF-DSP 88-U
-42-
Open the central control command window and select the parameter to be controlled on the DSP GUI inte rf ace.
The window will display the current command immediately. Copy the command and then use UDP or RS232 to send
the command to the device form external control interface.
(2) Device upgrade
Device upgrades can be carried out through UDP. Connect the device, click setting-help-device upgrade. A file
choice pop-up box will appear, navigate to, and choose the processor upgrade file (*.bin). Execute the update.

4. Control
4.1 External Control Programmer
The External control programmer supports UDP and RS232, and controls protocols for all control parameters of the
processor, including module parameter controls, parameter acquisition, and preset calling.
When UDP controls are used, the default port is 50000. Ports can be set in “Device Setting” in the DSP software.
When using RS232 controls, the default baud rate is 115200, data bits is 8, stop bit is 1, and parity set to ‘None’.
Similarly, they can be set in “Device Setting”. The interval between messages must be more than 100ms for RS 232
command sending.
If central control needs feedback and acknowledgement, please turn on ‘central control response’ in “Device
Settings”.
4.2 Control Protocol
Because of historical reasons, the latest control protocol adopts variable-length and is fully compatible with old
fixed-length control protocols. In protocols, the fourth byte is used to distinguish versions. 0- indicates V1 version
(previous versions) and 1- indicates V2 version (current protocol version).
The difference between V1 and V2 is that V1 may control all processing module parameters, but one command can
only control one parameter. If a parameter is needed to control continuous multiple channels, then V2 version must
be used. In othe r words, in a condition that users need to press one key on the key panel to trigger GPIO output
high- / low-level of devices, or send a command via RS232 / RS485, then V2 version will be the best choice.
