First Steps
Contents
You should have received the Caretaker Plus system unit, a power adapter, and this manual. Save the cardboard box and its polystyrene inserts. If you have ordered any additional cables they usually arrive in the same package.
Connecting the Cables
Cabling is one area to which you must pay careful attention. Consult the cabling guides in this manual for the correct pinouts. If you are not sure, give us a call, we will be happy to assist you. The shared device connects to the port labeled "0". The computers connect to port number 1 and higher.
Configuring the Caretaker Plus
The factory default settings (see Appendix D) are sufficient for most applications. To change the defaults, you configure the unit through port 1. To configure the unit you access the configuration menu or send commands as described later.
Configuring the computers
The final step in installation is to make sure that your computer's software is configured correctly, by setting the proper communication settings. If you use serial ports on PCs, you should have the proper DOS MODE statement in your AUTOEXEC.Bat file.
