Section 3. CONNECTING A COMPUTER
This section explains how to connect your personal computer to the RayTemp. Once connected,
you can view all of the front panel screens covered in the previous section. You can also retrieve
the recorded data and view color graphs of temperature and demand profiles. "PTT" is the option-
al software tool for your personal computers that works with RayTemp controls. It simulates the
front panel and retrieves logged data. PTT software and interface cables are available directly from
Raypak. The computer must be able to accept a serial (RS-232) cable.
Wiring pin assignments are provided below for building your own cables.
CAUTION! Never plug a telephone line into the RJ-11 connector! The contr
