16.5. Acknowledge Code and Error Codes
This is an explanation of erCd of the function list
<AK> (06h) ----Acknowledge in ASCII code.
In the Case of erCd 0
The balance does not output <AK> code or the error code.
In the Case of erCd 1
When the balance received a command requesting data and cannot process it, the balance transmits
an error code (EC, Exx). When the balance is able to process a command requesting data, the balance
outputs the data.
When the balance receives a command to control the balance and can not process it, the balance
transmits an error code (EC, Exx). When the balance receives a command to control the balance and
can proces
s it, the
balance
transmits <A
K> (06h)
code.
There are some commands that transmit plural <AK> (06h) code from the balance. See "Command
Examples"
CAL command (Calibration command)
P command (ON:OFF command)
R command (RE-ZERO command)
TST command (Calibration test)
When a communication error has occurred due to external noise, or a parity error has occurred due to
transmission error, the balance transmits an error code. In this case, send the command once more.
16.6. Control using CTS and RTS
This is an explanation of Ct5 of the function list.
In the Case of Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the CTS line to
HI. The balance outputs data regardless of the condition of the RTS line.
In the Case of Ct5 1
The CTS line is kept HI normally. When the balance can not receive the next command (ex. processing
last command), the balance sets CTS line to LO.The balance confirms the level of the RTS line when
data can be output. If the RTS level is HI, the balance outputs data. If the RTS level is LO, data is not
output (It cancels data output).
16.7. Related Settings
The balance has internal settings related to RS-232C output, "data output ( dout )" and "serial interface
( 5if )." Set according to usage.
