Connecting the RS-232 Interface
The RS-232 data communication interface supports the querying of status information and
temperature data from the oven by entering basic commands in a standard terminal window
provided by your computer’s operating system. The interconnection requires a standard
RS-232 cable with 9-pin connectors and a straight “1:1” pinout without any crossed wires,
which is not supplied with the oven.
Users may employ the RS-232 command inventory listed in Table 5-1 below for automating
process data logging - for example, by embedding these commands in scripts that run on a
remote computer.
Interconnecting the Oven with a Computer
1. Turn the computer off.
2. Route the serial interface cable along a path that does not cross hot exhaust air piping,
tables, aisles or passageways.
Power outlets
Make sure that power outlets remain freely accessible at all times!
Condensation
When taking the oven into operation for the first time allow some time for
stabilization before switching on to avoid condensation forming on live
parts.
