8. CONNECTION TO A COMPUTER SYSTEM
A. GENERALITIES
Connection to a computer system (Hartwall, Walla, Remenco, ...)
The coffee machine informs the computer (in real time) about the number of cups of coffee and tea
(made with temporized hot water). The computer is in charge of the management of the collected
coffee machine data.
Each barman has got a coded badge that gives him permission to use the coffee machine and directly
charge the served drinks.
B. MACHINE PREPARATION
Prior to being connected to a computer system, a coffee machine of the RUMBA range must be modified
as follows:
1. Ref. 45026 and 45027 (with memory dated 22/07/97)
The following equipment is also supplied:
2. An interface box that records impulses coming from units and hot water outlets and transmit
them to the computer
3. The cables connecting the interface to the coffee machine
4. A key switch to enter in programing mode.
