2. Indicator Description
1
PWR: power indicator. green, constant light -Power normal; Not light - Power abnormal.
2
LINK: multi-status indicator . three colors (Red. Yellow. Green), as follow:
Reference processing mode
Module bus state
LINK indicator state
Normal
No communication of module
No light
MPU has identified the module but no
communication
Constant light in green
Serial or parallel port in communication
Green jitter: indicator on 30ms and off 30ms
Parallel power supply not
enough, must connect to external
power supply
Without serial or parallel port in
communication
Yellow flicker: indicator on 0.5s and off 0.5s
With serial or parallel port in communication
Yellow is darkened and jitter alternately: indicator off 0.5s and
jitter 0.5s
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
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
