2. Indicator description
2.1 Indicator description of H04DT, H32DT
1
PWR
：
Power indicator, green. Normally on-power normal; off - power abnormal.
2
LINK: Multi-status indicator .three colors(Red. Yellow. Green) ,as follow:
Reference processing mode
Module bus state
LINK indicator state
Normal
MPU didn’t identify the module and no
communication
No light
MPU has identified the module but no
communication
Constant light in green
Serial(H32DT) or parallel port in communication
Green jitter: indicator on 30ms and off 30ms
Firmware upgrade failed, reupgrade
the module firmware
Without serial or parallel port in communication
Red flicker: indicator on 0.5s and off 0.5s
With serial or parallel port in communication
Red is darkened and jitter alternately: indicator off
0.5s and jitter 0.5s

0.5s and jitter 0.5s
Hardware failure and maintenance
Without serial or parallel port in communication
Constant light in red
With serial or parallel port in communication
Red jitter quickly: indicator on 30ms and off 30ms
3
RJ45 Ethernet indicator: there are two Ethernet LEDs, green and yellow, as shown on the right picture:
Color
Status description
Green light is always on
Physical connection of TCP module and external device is normal;
Green light goes out
TCP module fails to connect with external device or the module itself is abnormal
Yellow light blinks
TCP module is connected to an external device normally, and blinking frequency indicates
the data transmission speed. When speed is fast, human eye is not easy to distinguish it,
at this time, yellow light is long brignt.
Yellow light goes out
No data transmission communication of TCP module and external device
