Start-up
Connecting the RS-232 Interface
5-10 Heratherm Thermo Electron LED GmbH
With stacked devices, keep the serial interface cable away from hot spots on the other
oven 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 232
in the electrical interfaces
section at the rear of the oven (see “Signal Interfaces and Power Socket” on page 4-7 ).
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:00:Cn
, where:
—
?:
identifies the command line as a query;
—
aaaa:
is the parameter address;
—
:Cn
specifies the type of data to be queried (see the examples in Table 5-1 for
reference)
—
:00
is a response field (retained in the query for technical reasons) that must be left at
“00”;
—
<CR>
is for carriage return.
You will receive a response of the following general format:
!:aaaa:bb:XXXXX:cc<CR>
, where:
—
!:
identifies the line as a response to a query;
—
aaaa:
is the parameter address entered with the query;
—
bb:
is the number of payload bytes in hexadecimal code - for example,
1F
for the
decimal value
31
;
—
XXXXXX:
is the significant status information queried;
—
cc:
is a check sum (technically an inverted XOR of all bytes returned, excluding the
check sum bytes and the <CR> character);
