Instruction Manual Thermo Fisher Scientific
TCP Communication
Parameters
i Series Instruments support the Geysitech/TCP protocol over TCP/IP. The
register definition is the same as for the serial interface.
TCP connection port for Geysitech: 9882
Instrument Address
The Geysitech instrument address has a value between 0 and 127 and is
represented by 3 digit ASCII number with leading zeros or leading spaces if
required (e.g. Instrument address of 1 is represented as 001 or <SP><SP>1).
The instrument Address is the same as the Instrument ID used for C-Link
and MODBUS commands. This can be set via the front panel.
The Instrument Address is represented by <address> in the examples
throughout this document.
Note Device IDs 128 through 247 are not supported because of limitations
imposed by the C-Link protocol.
Abbreviations Used
The following is a list of abbreviations used in this document:
<CR> is abbreviation for Carriage Return (ASCII code 0x0D)
<STX> is abbreviation for Start of Text (ASCII code 0x02)
<ETX> is abbreviation for End of Text (ASCII code 0x03)
<SP> is abbreviation for space (ASCII code 0x20)
Basic Command
Structure
The following is the basic structure of a Geysitech command:
<STX>Command text<ETX><BCC>
OR
<STX>Command text<CR>
Each Command is framed by control characters, <STX> at the start and
terminated with either <ETX> or <CR>.
If a command is terminated with <ETX> then additional two characters
<BCC> is attached after <ETX>, this is the block checksum.
