Simulating a T-vo service signal Answered

Is it possible to simulate a t-vo service signal. I want to use a T-vo that I bought at a thrift sotre, to record my outside surveylance cameras, but it wont let me record without the service. Can I bypass this, or simulate a signal somehow? can I make a service simulator for this? I dont want to use it to record tv, I have a dvd recorder for that, just for the cameras.
