DATA TRANSFER MODE
There are five kinds of data transfer modes for RS-232C/422/485; “stream,” “auto print,” “manual print,”,“command”, and
“output per sampling.”
[Stream], [Auto Print], and [Manual Print]
The functions of these transfer modes are the same as described in 8-3 Standard Serial Output.
[Command]
This mode analyzes the “command” received from the host computer, etc. provides relevant processing, and responds
with a result. For example, if an “MT” command is received, the tare will be subtracted and its result (whether tare
subtraction is allowed or not) will be sent as a response.
The address capability is available only in this mode.
[Output per Sampling]
There are two types; gross and net. This mode outputs the setpoint state as well as weights. This is stream operations
outputting at a rate of 100 times/second in synchronization with sampling.
TRANSMISSION FORMAT
There are three kinds of transmission format; “A & D standard format”, “Accumulation data format”, and
“Output-per-Sampling format.” ( Outputs data 100 times per second synchronized with sampling.)
The A & D standard format used for this weighing indicator consists of two headers, data, unit, and a terminator.
