6 Connectors, Configuration and Connections
The installation procedure should only be carried out by an authorised, skilled technician: an incorrect
connection or a mistake when configuring the keyboard could lead to faulty operation, even of the other
peripherals installed in the system.
6.1 Connectors
The DCTEL keyboard has two RJ11 connectors on the back (only one for the DCBD), a 4-position Dip
Switch and a connector for the power supply jack:
6.2 Configuring the keyboard
The configuration phase allows the keyboard to be set up for optimal operation, based on system
requirements. Configuration should by carried out at the time of installation by the installer-technician and
eventually later in case of changes to the system type. We recommend to proceed with the parameters
properly, in order to prevent installation problems.
The following diagram shows the configuration dip-switches situated on the back of the keyboard:
