Setup Query instrument block properly for TCPIP

Hello,

I'm trying to readout the current and voltage of a SM3300 series power supply from Delta Elektronika. It's connected through TCPIP (Ethernet cable) to my mac. I've already got the queries working on my terminal so I'm sure there is a connection and I can communicate with the device. Now i'm trying to make it work in Simulink in order to log the data at a higher frequency. However, when running the simulation. It wait for the whole simulation time (5s) and then returns an error like: "response from device is empty"

I suppose it has something to do with firewall settings not letting simulink establish outgoing connections. Unfortunately I do not know how to fix this. Can anyone help me out?

Thank you!

For the Query instrument block I use the following settings:

-----

Block sample time: 1

Time out: 10

Buffer size: 512

Interface: TCPIP

Remote host: '169.254.0.2' (Same as what works from the terminal)

Port: 8462

Instrument initialisation: "None"

Query Command 'meas:curr?'

Instrument Response:

Data Format: Binary

Precision: 16 bit integer

Byte Order: Little Endian

Binary values to read: 16

Response output after initial response:

Repeat query for new data
