Keep the delay time above 0.5 ms between the last response and the next command.
Set response time (tr).
Use a long delay time, when there is noise.
Hi-Z: Hi impedance
Caution
If next command is transmitted from computer within 0.5 ms from the end of
last command, an interface error may may occur.
Waiting time from command to
response: tr. Set tr at [ r5 f- 9 ].

Communication Modes

Communication Modes Communication Modes Communication Modes
There are six following.
Stream Mode
The data is output on each display update. If the data can not be output completely
due to a slow baud rate, the data is output at the next update.
Auto Print Mode
The data is automatically printed on batch finish.
Total Print Mode
When entering the PRINT command, data is printed.
The PRINT command can be assigned to the control I/O, OP-05, F1 key or F2 key
Manual Print Mode
When the preset print key is pressed or the assigned terminal is connected, the data
is output.
Command Mode
This mode is used to control the indicator, to store parameters and to read data or
parameters. Use multiple drop connection.
Jet Steam Mode
The weighing data and state is output 100 time/s. The data is the gross or net value.
The format is the same as the command RGRS or RNET.
Set the baud rate to 38400 bps. If another baud rate is used, mis-sampling may occur.
Output data is repeated according to the number of
divider
