D-2 Model 48i Instruction Manual
iSeries instruments support the Gesytec protocol over TCP/IP. The register
definition is the same as for the serial interface. Up to three simultaneous
connections are supported over Ethernet.
TCP connection port for Gesytec:
The Gesytec instrument address has a value between 0 and 127 and is
represented by a 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.
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)
The following is the basic structure of a Gesytec 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 two additional characters
<BCC> is attached after <ETX>. This is the block checksum.
Block Checksum Characters <BCC> may be added to the command to
prevent processing invalid commands.
