3. Making the Right Connections
There are a number of programming options in the D6500 MPU program that affect the output of the D6500 to
an automation system. This section will serve as an addendum to the
D6500 Program Entry Guide (74-07253-
000) and the D6500 Operation and Installation Manual (74-04651-000).
3.1 Setting the Jumpers on the D6515 MPU Terminator
WARNING!
Before adjusting any jumpers, make sure the D6500 Receiver is powered down as
described in the
D6500 Security Receiver Operation and Installation Manual.
The D6515 MPU Terminator Card can be accessed from the back of the D6500 Receiver. The J3 Configuration
Jumper on the MPU Terminator Card can be configured in two different ways (see Figure 1). Mode 1 uses RTS,
CTS, DSR and DTR protocols and can be used with either Data Terminal Equipment (DTE) or Data
Communication Equipment (DCE). In a Mode 1 configuration the automation system must first give permission
before data is sent. In Mode 2 the automation computer is always ready to accept data.
