factory defaults: Use a pointed object, such as a straightened paper clip or 
toothpick, to press the reset button. This will cause the Ready LED to 
blink on and off. The factory defaults will be loaded once the Ready LED 
stops blinking (after about 5 seconds). At this point, you should release

Indicates an IP conflict, or, the 
DHCP or BOOTP server did 
not respond properly or a relay 
output occurred. Check the 
relay output first. If after 
resolving the relay output the

then there is an IP conflict, or 
the DHCP or BOOTP server 
did not respond properly.

Adjustable pull high/low resistor for RS-422/485 (150 K

Ω

 or 1 K

Ω

)

 

JP4, JP5

 

Jumpers are used to set the pull 
high/low resistors. The default is 
150 K

. Short the jumpers to set 

this value to 1 K

. Do not use the 

K

 setting with RS-232 mode, 

since doing so will degrade the 
RS-232 signals and shorten the 
communication distance.
