Installation procedures
Connecting the RS-232 Interface
Thermo Scientific Heratherm IMP 5-9
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 refrigerated incubator 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,
Peltier elements, stacked devices, tables, aisles or passageways.
With stacked devices, keep the serial interface cable away from hot spots on the other
refrigerated incubator in the stack.
3. Connect one connector of the serial interface cable (cable length, 5 to max. 10 m, not
supplied as a standard item) to the socket labeled RS 223 in the computer and alarm
interface section at the rear of the refrigerated incubator (see “Signal Interfaces and Power
Socket” on page 4-13 ).
4. Connect the second connector to an unused COM 1 /COM 2 or other serial port on the
computer.
5. Boot the computer.
6. Launch your standard terminal program and set up the connection with the following
parameters:
— 57600 bits per second
— 8 data bits
— 1 stop bit
— No Parity
7. Once your terminal indicates that serial communication has been established successfully,
enter any of the commands listed in table 5-1 below, depending on what type of
information you want to query.
8. Use the following generic command syntax:
?:aaaa:bb::cc<CR> , where:
— ?: identifies the command line as a query;
— aaaa: is the parameter address;
RS-232 interface compatibility
To avoid overloading and damaging the RS-232 interface check the
interfacing parameters against the pin-out description given above and
make sure that computer’s interface port works with a signal level of +/-
5V
DC.
