.I set a GPIF to a !articular value lan"ua"e for !ro"rammin". ow do I find out if this lan"ua"e can e used to !ro"ram and control the relay

module%

A.+ind out if the lan"ua"e of interest su!!orts some $ind of PIs(+unctions(Com!onents for serial communication. If it

does' most li$ely you should e ale to use that lan"ua"e with this module.

.hat is the connector mar$ed as IC)P on this module%

A. Ahis connector is used to !ro"ram the on3oard microcontroller. Ahis connector is !rimarily intended for factory use.

.I need a customiHed version of this !roduct' can /umato do the customiHation for me%

A.:es' we can definitely do customiHation ut there may e minimum order re#uirements de!endin" on the level of
