7. State of RINKO FT:
State
normal
preheat
sleep
8. Error code:
Error Code
0001
0002
0003
Miscellaneous:
- The GND terminal for RS-232C is same with that of the power supply.
- For UART connection, use same GND terminal for both the RINKO FT power GND and the HC transceiver IC.
- For RS-232C connection, establish the communication line
before
turning on the power of the RINKO FT.
Checksum error.
Description
Description
The
Request
command could not be interpreted.
RINKO FT is in sleep mode.
In this state, the analog electronics power is OFF and the CPU is in low-power mode. See also Chapter 3.
- LEDs phase and amplitude are for an easy diagnostic in case of trouble. Also, LEDs phase and amplitude AD values are needed by the
instrument to internally calculate the AD values of DO. The physical values of DO can be converted from the AD values of DO using the
equation provided in the manual section 9.5.
First response from the sleep mode.
RINKO FT returns
Error Code
0003 to
any first command (even if it is “wu”)
while it is in the sleep mode. After the
Error Code
0003, only the CPU wakes up and starts to accept any command appropriately. Therefore, please
RESEND the same
Request
. If the
RINKO FT does not receive any command for 2 minutes, the CPU will enter the low-power mode again. See also Chapter 3.
RINKO FT is in normal operation mode.
In this state, RINKO FT continuously measures and updates data every 1 s (but does not output/record data). When receiving a
command to output data, RINKO FT outputs the latest data.
RINKO FT is in preheat state.
RINKO FT is already waked up, but the sensor is preheating. In this state, measured DO is unstable and unreliable.
