You can also add accessory equipment to the system that plugs into the control unit. You can add a data collector and printer to your system to collect data on calls and print Call Reports. The 450F adapter allows the data collector to share port 19 with the Busy Buster feature. Refer to the MERLIN Plus System Manual for more information on Busy Buster. See Figure 28.
You may also add a Basic Telephone and Modem Interface (BTMI) in order to connect a basic telephone, dialing modem, or facsimile machine to the system. See Figure 29.
