SPH unit can accept a special communication function card in this slot. There
are 2 kinds of cards available now. One is an RS485 card and the other is a
SNMP (Simple Network Management Protocol) card. In the future, other
cards may be developed. For detailed information, please refer to the
instruction manual of the individual card.
