A central controller (104) for a multipoint polling system arranged to collect inquiry messages from data terminals (102a-n, 103a-n) for processing by a data base (101) and for distributing response messages to the terminals, the several terminals using different communication protocols. The controller includes a RAM memory (203) which stores a list of items, each item identifying a terminal and the type of protocol used thereby, a ROM memory (202) which stores an instruction set for each protocol type and a microprocessor (201) which sequentially accesses each item on the list to poll the associated terminal and accesses the instruction set identified in the item to control sending and receiving equipment to query and intercommunicate with the selected terminal in accordance with the accessed instructions.
