16.3 REMOTE KEYBOARD CONNECTION
It is possible to connect to the instrument up to two remote terminals VI622, available with / without
temperature probe on board, or two TI620 available without temperature probe on board, or an LCD
keyboard Visograph 2.0 (V2I820 without probes on board).; the use of keyboards VI622 or TI620
excludes the possibility of use of the keyboard Visograph and vice versa.
If the remote terminal VI622 is provided with temperature sensor on board, the temperature
adjustment can be performed with the probe at the edge of the terminal.
To enable the remote keyboard is necessary to configure the following parameters (in the Ichill
parameter map):
• CF54 Enable remote terminal 1 (VI622 EVO, TI620)
• CF55 Enable remote terminal 2 (VI622 EVO, TI620)
• CF84 Enable remote terminal Visograph (V2I820)
The connection of the remote terminals must be performed using a shielded / twisted (such as
Belden 8772, wires 1 mm
2
minimum); the maximum cable length to connect the keyboard VI 622 is
100 mt (maximum length of the connection, both if using one or two keyboards), and the maximum
cable length to connect the keyboard Visograph is 60 mt..
In case of lack of communication between the device and the keyboard (wrong connection, wrong
configuration parameters), the display shows the message "noL" (no link).
When using two keyboards VI622 you must configure the dip switches on the rear of the same,
giving to the first keyboard address 1 and to the second keyboard address 2.
