SCADA INTERFACE INSTRUCTIONS - OPTION 21S - FOR A75D/A75DE SYSTEMS

Default Settings Protocol: Modbus RTU Comm Port: RS232 (J2) Baud Rate: 9600 (Selectable 1200, 2400, 4800, 9600, 14400, 19200, 38400) Data Bits: Fixed at 8 Stop Bits: Fixed at 1 Parity: None (Selectable None, Even, Odd) Flow Control: Fixed at None Modbus Address: 1 (Selectable 1 to 247)

Changing the Settings In all likelihood it will be necessary to change the settings from the factory default settings to properly integrate a new charger into your SCADA Network. To change the above settings one must enter the "Customer Calibration" mode. This is accomplished by pressing and holding the UP Arrow Button followed by pressing and holding the MODE Button. Both buttons must be pressed for 5 seconds. When the control card enters the Customer Cal mode the display will show "Customer Calibration Mode" for 2 seconds. During the time the display shows "Customer Calibration Mode" release both buttons. The purpose of the Customer Cal is to allow one to change settings in the field. The following setting changes are allowed in the following order: ♦

Low Voltage Alarm Voltage Threshold



End of Discharge Alarm Voltage Threshold



High Voltage Shutdown Alarm Voltage Threshold



High Voltage Alarm Voltage Threshold



Low DC Current Alarm Threshold



Equalize Timer Mode



Equalize Cycle Time



LCD Backlight Timer Setting



Modbus Address



Modbus Baud Rate



Modbus Parity

Setting the Modbus Address The following setting is used to set the Modbus: ♦

Modbus Address

You may change the address by pressing the UP or DOWN Arrow Buttons. When you have set the baud rate you wish to use press the MODE button to go to the next setting.

Setting the Modbus Baud Rate The baud rate may be set to the following: 1200, 2400, 4800, 9600, 14400, 19200, 38400 The following setting is used to set the Baud Rate: ♦

Modbus Baud Rate

The LCD display will show “Modbus Baud Rate” on the first line and second line will flash the actual baud rate that is in use. You may change the baud rate by pressing the UP or DOWN Arrow Buttons. When you have set the baud rate you wish to use press the MODE button to go to the next setting.

Setting the Modbus Parity Type The Parity may be set to the following: None, Even, Odd The following setting is used to set the Parity: ♦

Modbus Parity

The LCD display will show “Parity Type” on the first line and second line will flash the actual Parity type that is in use. You may change the Parity by pressing the UP or DOWN Arrow Buttons. When you have set the Parity you wish to use press the MODE button to go to the next setting.

RS232 & RS485 Connection Information IMPORTANT NOTE: Jumper pairs JP13/JP14 and JP15/JP16 on the S2A-388S board determine which port (RS232 or RS485) is utilized for communications. For RS232 the jumper(s) must be positioned on JP14 and JP16. For RS485 the jumper(s) must be positioned on JP13 and JP15. RS232 Port Connection RS232 communications are accomplished through J2A on the P60-388S board. The RS232 Port is a galvanically isolated interface. The RS232 interface is configured as DTE. The default settings are 9600 baud, 8 Bits, No Parity, 1 stop bit and no flow control. RS485 Port Connection (s) for Terminal Strip Equipped Cards The RS485 (TS1) port is a 3 pin terminal strip. The RS485 Port is an isolated interface. The RS485 interface is "two wire" thus no handshaking takes place. The default connection would be 9600 baud, 8 Bits, No Parity, 1 stop bit and no flow control. The RS485 interface may require configuration of jumpers JP1/JP2 and JP5/JP6 and JP3/JP4 on the P60388S card. Jumper pairs JP1/JP2, JP3/JP4 insert or remove the biasing loads. Jumper pair JP5/JP6 inserts or removes the terminating resistor. BIAS Resistors IN place jumpers(s) on JP2 and JP4. BIAS Resistors OUT place jumpers(s) on JP1 and JP3. Termination Resistor IN place jumpers on JP6. Termination Resistor OUT place jumper on JP5.
