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.
