Connecting the RS-232 Interface
Fisher Scientific
Peltier Low Temp. Incubators 5-9
Users may employ the RS-232 command inventory listed in
below for automating
process data logging - for example, by embedding these commands in scripts that run on a
remote computer.
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.
Interconnecting the low temperature 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,
tables, aisles or passageways.
With stacked devices, keep the serial interface cable away from hot spots on the other low
temperature 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 low temperature incubator (see
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
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;
