Πρώτα βήματα με phidgets και vb.net

Γεία σας!

Φτιάχνω ένα project με phidgets και VB 2010.

Έχω

ένα RFID kit

http://www.phidgets.com/products.php?category=14&product_id=2002

ένα interface kit 0/0/4 (τέσσερα ρελε χειριζόμενα από usb)
http://www.phidgets.com/products.php?category=9&product_id=1014

και μια οθόνη με interface kit (8 αναλογικές είσοδοι, 8 ψηφιακές είσοδοι, 8 ψηφιακές έξοδοι)
http://www.phidgets.com/products.php?category=19&product_id=1202

Με την χρήση των παραδειγμάτων που έχει το site κατάφερα και τα έβαλα όλα μαζί σε ένα πρόγραμμα.

Περνάω ένα tag από τον αναγνώστη και βλέπω την αντιστοιχία που έχω καθορίσει στο πρόγραμμα.

Το πρόβλημά μου είναι όταν προσπαθώ να αντιστοιχίσω tag σε ρελε.

Ο κώδικας των ρελέ, είναι γραμμένος ώστε ανάλογα με τον αριθμό των outputs που διαβάζει από το interface kit, τόσα checkboxes να εμφανίζει.

Όταν γράφω όμως μέσα στο if να τσεκάρεται το checkbox αν περνάει το συγκεκριμένο tag τσεκάρεται μόνο το κουτάκι, αλλά το ρελέ δεν ενεργοποιείται.

Αυτός είναι ο κώδικας. Μήπως μπορείτε να με βοηθήσετε?

Στην σειρά 854 είναι η συνθήκη που θέλω.

Στη σειρά 760 είναι το digiOutArray(0) που θέλω να ενεργοποιηθεί. Και το digiOutArray(0).Checked = True το ίδιο αποτέλεσμα είχε.

Στην 440 σειρά ξεκινάνε οι ψηφιακες έξοδοι.

Το checkbox ανοίγει με το ρελέ όχι.
' - InterfaceKit full -
' In this example we display the interface kit details including the number of inputs and outputs it allows,
' and displays the values of the inputs and outputs.
' Note: This example was developed and run with an LED in digital output 0 and an LED in digital output 7 to test
' the simulated digital output.
'
' Please note that this example was designed to work with only one Phidget InterfaceKit connected. 
' For an example using multiple Phidget InterfaceKits, please see a "multiple" example in the InterfaceKit Examples folder.
