Conifigure two networks with 4 Xbees

Hi Guys,
I have four XBees and I want to set up two separated Networks which are not interacting. Let’s say:
XBee 1 is sending data to XBee 2. (both XBee Series 1)
Xbee 3 is sending data to XBee 4. (both XBee PRO Series 1)

My problem is that I receive some garbage with XBee 4 sometimes.

My Question is how to set Destination Adress and My Adress, to prevent the two networks to interact each other.

I left everything by default with XBee 1 and 2:
Channel: C
PAN ID: 3332
Destination adress High: 0
Destination aderss Low: 0
My Adress: 0

I changed for XBee 3 and 4:
Channel: 16
PAN ID: 1234
Destination adress High: 0
Destination aderss Low: 1111
My Adress: 1111

But there are still transcription errors within XBee 3 and 4. (Means connection works, but some samples are just rubbish)

I’m using XCTU to program the XBees.
I tried a lot of combinations and I’m freaking out if I try some more…Can anyone help me?

You are not getting the data from the two networks. You are getting the garbage from another location or from something else.

Hi mvut,
well then, how do you explain that the garbage just starts in the moment when I start the second network? Each Network on its own works perfect.

I read that MY Adress and Destination adress should be flip-flop for receiver and transmitter. So I tried this setup, but it’s still the same problem:

XBee PRO Nr. 1:
Channel: 17
PAN ID: 1234
Destination adress High: 0
Destination aderss Low: 2222
My Adress: 1111
Scan Channels: 0040
Baudrate: 57600

XBee PRO Nr. 2:
Channel: 17
PAN ID: 1234
Destination adress High: 0
Destination aderss Low: 1111
My Adress: 2222
Scan Channels: 0040
Baudrate: 57600

XBee Nr. 3:
Channel: D
PAN ID: 4343
Destination adress High: 0
Destination aderss Low: 4444
My Adress: 3333
Scan Channels: 4
Baudrate: 9600

XBee Nr. 4:
Channel: D
PAN ID: 4343
Destination adress High: 0
Destination aderss Low: 3333
My Adress: 4444
Scan Channels: 4
Baudrate: 9600

with the “Scan Channels Mask” the Xbees should be forced to scan only this singel channel and not to use other channels, right?

I’m still not getting into it.
Would be pleased if someone has an idea.
