12Connection of the Graphic terminal (standard)The terminal can be installed at a maximum distance of 500 metresfrom the microPC control board.- Up to 50 metres, it can be connected directly with telephonewire.- From 50 to 200 metres, it is necessary to use the TCONN bypasscards and AWG 20/22 shielded cable with 2 twisted pairs.AC/DCconverter230VacJ14 y J15 in 2-3pLAN - to next TCONN by-pass cardAWG20/221 twisted pair+-20-30VdcGraphic terminal in the left connectorTCONNGraphic terminalRJ12- From 200 to 500 metres, it is necessary to use the TCONNbypass cards, AWG 20/22 shielded cable with 1 twisted pairand external 20...30Vdc (150 mA) power supply.S90CONN0020,8 mTCONN TCONNGraphic terminalRJ12“50FC”200 mConfiguration:To ensure communication between the Graphic terminal and thecontrol board, the terminal must be configured with address 16.In the event of a terminal supplied separately, this is not sentaddressed and the following procedure must be carried out:1) Simultaneously press the + + keys.2) On the screen accessed, set address 16 in:«Display address setting.Note: If the terminal is going to be integrated into the pLAN, referto the chapter 17, which explains the configuration of the terminalsin the network.Connection of the User terminal (optional)The terminal can be installed on the RS485 Filed-bus at amaximum distance of 100 metres from the control board.The connection requires the following:- Power supply (the same as the control board) at 230Vac 50/60Hz(L&N): 2 wires (section 0.5 at 1.5 mm 2 ).- Communication with the board (RX+/TX+ & RX-/TX-): shieldedcable type AWG20 or AWG22 with 1 braided pair + drainwire +shielding (e.g., model BELDEN 7703NH).Rx-/Tx-Rx+/Tx+GNDL 50/60HzN 230V~Rx-/Tx-Rx+/Tx+GNDShieldingCable of Belden7703NH typeJ1- GNDJ1 - 230 Vac120ΩTx-GNDTx+120ΩM(G0)User terminalTx-Tx+GND+(G)J10“50FC”Rx-/Tx-Rx+/Tx+GNDL 50/60HzN 230V~Important: It is recommended to insert an electrical resistanceof 120Ω, between connectors TX+ and TX- of the board output(connector J10) and on the final component of the RS485 network,to avoid potential problems of communication.Configuration:To ensure communication between the User terminal and thecontrol board, the terminal must be configured with address 10and speed 9600 bps.The terminal is sent addressed, and on the power up, the screenshould display the firmware version “1.1” on the power up and,then, the “init” symbol. The terminal will be fully operationalafter a few seconds.In the unlikely event of a communications failure the screen willdisplay “Cn”.
