Heracell Vios 160i / 250i CR
Thermo Scientific
The interface transmission speed can be selected within the defined baud rates (9,600, 19,200,
38,400, 57,600 Baud) at the touchscreen of the
Heracell Vios 160i / 250i CR
(see “ Settings / Setup”
on page 6-17 ).
Structure of the Command Sequences for Data
Communication
All characters sent and received in the data exchange between a computer and the incubator
Heracell
Vios 160i / 250i CR
are ASCII characters that can be displayed on a conventional terminal.

This ensures that communication can be set up, controlled, and programmed easily.
Description of Protocol
Character coding

ASCII characters, capital letters are not allowed.
Reading parameters:

Query: ?:aaaa:bb::cc<CR>

or: ?:aaaa:bb:XXXX:cc<CR>

Response: !:aaaa:bb:XXXXX:cc<CR>

where: aaaa = parameter address

bb =amount of payload in this telegram (00 – ff )

cc = checksum: CRC8-CCITT: x8 + x2 + x1 + 1 = 0x07

without cc and <CR>

XXXX = bb-bytes user data
Description of the response elements:

aaaa parameter address

bb amount of payload in this telegram (00 – ff )

cc Checksum: Inverted XOR of all bytes without

checksum and <CR>
Example of a software version query (50111927):

Query: ?:0001:00::cc<CR>

Response: !:0001:08:50111927:cc<CR>
Writing parameters:

Command: !:aaaa:bb:XXXXX:cc<CR>

Response: !:aaaa:bb::cc<CR>

where: aaaa = parameter address

bb =amount of payload in this telegram (00 – ff )

cc = checksum: CRC8-CCITT: x8 + x2 + x1 + 1 = 0x07

without cc and <CR>

XXXX = bb-bytes user data
Response with an error message:

Response: !:aaaa:bb:XX:cc<CR>
