Gesytec Commands

D-4 Model 5030i SHARP Instruction Manual Thermo Fisher Scientific

If the received command does not satisfy the above formats, or if the

<address> does not match the Instrument Address, the command is

ignored.

This is a sample command to switch the instrument to initiate a filter

change, instrument address 14:

This command initiates a data transfer from the instrument. The

instrument responds with measurement data, which depends on the range

mode and is listed in “Measurements reported in response to DA

command” below.

The command structure for a data query command is as follows:

The <address> is optional, which means it can be left out completely. The

<address>, if present, must match the Instrument Address. Additional space

can be present after the <address>.

If the <address> is left out, then no space is allowed in the query string.

A command with no address is also a valid command.

The following are the different acceptable formats of the DA command

with Instrument Address 14:

The data query string is valid and will be answered with data transmission

only if the command starts with <STX>, which is followed by the

characters DA, and the <address> (if present) matches the Instrument

Address, and the command is terminated with either <CR> with no

checksum or <ETX>, followed by the correct checksum <BCC>.
