5.4 Installing the Aria terminal
The connection between terminal and pCO is made using AWG20/22 shielded cable only. To connect the cable to the terminal, proceed as follows.
1) Disconnect power to the terminal.
2) Separate the front of the terminal from the bottom shell (for further details, see the user manual or the instruction sheet).
3) Fasten one end of the cable shield to the terminals marked “GND”, “Rx/Tx+” and “Rx/Tx-” in the bottom shell.
4) Close the terminal again.
To connect the cable to the pCO, the end not connected to the Aria terminal must be terminated with a 3-pin plug-in connector, then plug this into connector:
• J6 on the pCO
XS

• J11 on the pCO

The Aria terminal communicates with the pCO boards by exchanging variables across pLAN. As the code that manages the terminal is resident in ROM, and therefore
cannot be changed depending on the devices that make up the network (as normally occurs for pCO boards), the terminal can receive variables from any device in the
network, but can only send data to one device, selected by the user. Overall, there are five parameters used to configure pLAN communication on the Aria terminal:
• L1
L1L1
L1: pLAN address of the Aria terminal (between 1 and 31);
• L2
L2L2
L2: pLAN address of the device the variables are sent to (between 1 and 31);
• L3
L3L3
L3: pLAN page (between 0 and 255);
• L5
L5L5
L5: used to selectively inhibit the reception of some variables;
• L6
L6L6
L6: communication protocol over RS485 line, selectable as pLAN or CAREL Slave.
For further information on the parameters and on the variables that can be exchanged, see to the user manual.
The Aria terminal parameters can be set on the keypad or by copying the settings from a hardware key programmed previously using a sample device. In the first case
(programming by keypad), proceed as follows:
1) power up the terminal;
2) press the SET and MODE buttons together: the terminal will display a screen for entering the enabling code;
3) using UP or DOWN enter the code “22” and confirm by pressing SET: the terminal enters parameter configuration mode, showing a screen similar to the one
below (the code at the bottom is the name of the parameter, while the number at the top is the value of the parameter).
4) Press the UP and DOWN buttons until the terminal shows the desired parameter.
5) Press SET to make the change: the selected parameter flashes.
6) Enter the desired value using the UP and DOWN buttons, then confirm by pressing SET.
7) Exit programming mode by pressing the HOLD button.

Important: after having changed the pLAN address (parameter L1), turn the terminal off and on again for the changes to take effect.
If wanting to set the parameters using a hardware key, first of all copy the parameters from the sample device as follows:
1) connect the key;
2) power up the sample device by pressing and holding SET and DOWN;
3) the device starts copying the data to the key: the display shows the message “EC”;
4) at the end of the copy operation the message OK or NO is shown, depending on the outcome of the data transfer.
To then copy the parameters from the removable hardware key to the terminal, simply proceed as follows:
1) connect the key;
2) power up the terminal by pressing and holding the UP button;
3) the terminal starts copying the data from the key: the display shows the message “CE”;
4) at the end of the copy operation the message OK or NO is shown, depending on the outcome of the data transfer.
