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 M DE 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

Setting the Modbus Address
The following settings are used to set the Modbus Address so the communications card can communicate
with the controller card:
♦Modbus Address
Press the D WN Arrow button until the address is set to ALL. The ALL setting sets the controller card up
so it will accept commands from the communications card. It also activates the following calibration
settings which will allow you to tailor the communications card to your specific SCADA requirements.
When the modbus address is not set to ALL the controller card may not be able to communicate with the
communications card.
To advance to the next setting you must press the M DE Button.
Setting the Scada Protocol
The communications card is equipped with 4 methods of communicating, DNP 3.0, Modbus ASCII,
Modbus RTU and Modbus TCP.
The following setting is used to set the Scada Protocol:

The Communications card may be set to communicate over an RS232 or RS485 network at the following
Baud Rates:
1200, 4800, 9600
The following setting is used to set the Baud Rate:
♦Scada Baud Rate
The LCD display will show “Scada 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 D WN Arrow Buttons. When
you have set the baud rate you wish to use press the M DE button to go to the next setting.
Setting the Scada IP Address
This setting will not appear in the sequence if the Comm Port has been set to RS232 or
RS485.
The following settings are used to set the IP Address:
♦Scada IP Address
The LCD display will show “TCP IP Addr” on the first line and the actual IP Address on the second line.
The number flashing is the 3 digit quadrant of the IP Address you may adjust by using either the UP or
D WN Arrow buttons. Each 3-digit quadrant is set individually. Pressing the M DE button will cause the
next 3-digit quadrant to flash. After all 4 quadrants have been flashed the cal sequence will advance to
the next setting.
For example: You would like to change the IP Address from the default setting of 192.168.000.006 to

Setting the Scada Netmask
This setting will not appear in the sequence if the S2A-302S Comm Port has been set to
RS232 or RS485.
The following settings are used to set the Netmask:
♦Scada Netmask
The LCD display will show “TCP Netmask” on the first line and the actual Netmask on the second line.
The number flashing is the 3 digit quadrant of the Netmask you may adjust by using either the UP or
D WN Arrow buttons. Each 3-digit quadrant is set individually. Pressing the M DE button will cause the
next 3-digit quadrant to flash. After all 4 quadrants have been flashed the cal sequence will advance to
the next setting.
For example: You would like to change the Netmask from the default setting of 255.255.255.000 to
255.255.000.000
When the LCD display shows “TCP Netmask” and the ‘”255” is flashing press the M DE Button.

This setting will not appear in the sequence if the S2A-302S Comm Port has been set to
RS232 or RS485.
The following settings are used to set the Gateway:
♦Scada Gateway
N TE: A Gateway setting of “000.000.000.000” is equivalent to not having a Gateway Setting. Thus if
you are not sure if you need to set the Gateway then leave it at the default of “000.000.000.000”.
The LCD display will show “TCP Gateway” on the first line and the actual Gateway on the second line.
The number flashing is the 3 digit quadrant of the Gateway you may adjust by using either the UP or
D WN Arrow buttons. Each 3-digit quadrant is set individually. Pressing the M DE button will cause the
next 3-digit quadrant to flash. After all 4 quadrants have been flashed the cal sequence will advance to
the next setting.

the flashing digits become “011”.
The Gateway is now set to 192.168.000.011
Setting the Scada Diagnostics Mode
This setting when set to YES places the communications card into a mode where it is then possible to
utilize a program such a HyperTerminal to check communications. This capability has been added in
recognition that not all installers will have a software program capable of simulating a master station with
the selected protocol. The default selection for this setting is N . Setting this to YES places the
communications card into a mode where you can confirm communications using HyperTerminal. In this
mode the communication board will send out an ASCII character message that says “Press a key” every 4
seconds. The characters will be sent out using communications parameters you have entered. When you
see this message you are confirming that the communications card is capable of transmitting on the port
using the settings you have selected. When you press a key the communications card will reply saying
“You pressed the X key” where X is the key you pressed. If you see this then the card is transmitting
and receiving properly. P EASE NOTE YOU MUST RETURN TO THE CA SEQUENCE TO
DEACTIVATE THIS MODE OR RESET THE CONTRO ER CARD.
To advance to the next setting you must press the M DE Button
At this point the controller card will exit the calibration sequence and return to normal operation.

RS232, RS485 & TCP Connection Information
RS232 Port Connection
RS232 communications are accomplished through J2. 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.

SCADA INTERFACE INSTRUCTIONS - OPTION 21P /21Q – FOR A75DE SYSTEMS
Page 8 of 23
RS485 Port Connection (s) For RJ11/Phone Jack Equipped Cards
The RS485 (J3, J4) ports are parallel RJ11 jacks. Thus you may connect to either J3 or J4. The RS485
Ports are galvanically isolated. 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, JP3/JP4, JP5/JP6 on the P60-302S
card. JP1/JP2, JP3/JP4 serve as biasing loads. JP5/JP6 serves as a terminating load. Each jumper is
marked with RIN (the jumper position places the load resistor in the circuit) or R UT (the jumper
position places the load resistor out of the circuit). The positioning of these jumpers will depend on the
configuration of your RS485 network. Typically a network using a device like B&B Electronics RS232 to
RS485 converter (Part Number 485SD9RJ) would not require the use of the biasing load resistors thus
the jumper’s configuration for JP1/JP2 & JP3/JP4 would be to position the shorting jumpers on JP1 and
JP3 for all P60-302S cards placed on this network. If you do not have these biasing resistors already
somewhere on the RS485 network then you will need to place the shorting jumpers on JP2 and JP4,
JP5/JP6 will need to be placed on JP6 for P60-302S's that are in the first and last position on the RS485
network. The B&B device I have mentioned above does not provide a terminating resistor. The RS485
jacks on the P60-302S board are 6 position RJ11 jacks. nly positions 2,4,5 have connections. Pin 2 is
Data A (-), Pin 5 is Data B (+) and Pin 4 is the Signal Ground. RJ11 jacks are configured such that when
you face them (looking into the jack) Pin 1 is left most position and Pin 6 is the right most. For good
signal quality it is advisable to use shielded twisted pair cable in your RS485 network (B&B Electronics,
Part Number ETC8504 or ETC8505).

RS485 Port Connection (s) for Terminal Strip Equipped Cards
The RS485 (TS1) port is a 3 pin terminal strip. The RS485 Ports are galvanically isolated. 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, JP3/JP4, JP5/JP6 on the P60-302S
card. JP1/JP2, JP3/JP4 serve as biasing loads. JP5/JP6 serves as a terminating load. Each jumper is
marked with RIN (the jumper position places the load resistor in the circuit) or R UT (the jumper
position places the load resistor out of the circuit). The positioning of these jumpers will depend on the
configuration of your RS485 network. Typically a network using a device like B&B Electronics RS232 to
RS485 converter (Part Number 485SD9TB) would not require the use of the biasing load resistors thus
the jumper’s configuration for JP1/JP2 & JP3/JP4 would be to position the shorting jumpers on JP1 and
JP3 for all P60-302S cards placed on this network. If you do not have these biasing resistors already
somewhere on the RS485 network then you will need to place the shorting jumpers on JP2 and JP4,
JP5/JP6 will need to be placed on JP6 for P60-302S's that are in the first and last position on the RS485
network. The B&B device I have mentioned above does not provide a terminating resistor. The RS485
jacks on the P60-302S board is a 3 position terminal strip. Pin 1 is Data A (+), Pin 3 is Data B (-) and Pin
2 is the Signal Ground. The terminal strip is positioned such that when you face it (looking directly into
the strip) Pin 1 is the left most position and Pin 3 is the right most. For good signal quality it is advisable
to use shielded twisted pair cable in your RS485 network (B&B Electronics, Part Number ETC8504 or
ETC8505).

TCP Port Connection
The TCP Interface will require the use of a “Cross-over” cable if you are going to connect the P60-302S
card directly to a NIC on a PC. If you connect through a hub a “straight through” cable should suffice.
The Ethernet Port on the P60-302S is 10/100 Base-T compatible. The TCP Connection is accomplished
through a single RJ45 jack that is mounted to a daughter board on the P60-302S.

La Marche Communications Board Troubleshooting Guide
1) Verify operation of RED LED on the Communications Board.
The communications board (ECN 16236-02 and above) are equipped with a Red LED. This LED
indicates the following:
OFF: The board is not being powered or has failed. Check to see the cable is properly connected to
the 3-pin connector J5 on the communications card.
FLASHING: A problem with communications between the communications card and the controller
card has occurred. This is likely due to the cable connecting the controller card to the
communications card is disconnected or bad. This may also be due to the Modbus Address of the
controller card not being set to ALL. This LED will also flash when the controller card is in the Factory
or Customer calibration modes.
ON: This indicates the communications card and controller card are communicating properly.
2) Confirm proper configuration of Communications card for customer’s application.
The Communications card is shipped with the following default settings:
Comm Port: RS232 (J2)
Baud Rate: 9600
Data Bits: 8
Stop Bit: 1
Parity: None
Flow Control: None
Node Address: 00004
These settings may not be what are desired and the only way to change them is to enter the
customer calibration routine. The settings displayed in the customer cal routine should be checked to
make sure they coincide with the customer’s application
3) Confirm the correct type of cable is connecting the Communications board to the customer’s
application.
Refer to LaMarche Communications Card Cabling Guide Section for details.
4) Is the Communications card being used on an RS485 Network?
For an RS485 Network to function properly it must be properly biased and terminated. The
communications card is equipped with 3 configuration jumpers. JP5 removes the termination
resistor. JP6 adds in the termination resistor. JP1 & JP3 remove the biasing resistors. JP4 & JP6
add in the biasing resistors. Common practice with RS485 networks is to configure the last device in
a network (the device furthest from the master) with a termination resistor and the device closest to
the master or sometimes the master has the biasing resistors. Problems often occur when devices
are added and removed from a RS485 network without reconfiguring/checking the termination and
biasing resistor arrangement.
5) Testing Method.
The communications cards are tested at the LaMarche factory prior to shipment using the Triangle
MicroWorks Test Harness software program. Each of the ports (RS232, RS485 and Ethernet) is
tested. The next several pages show actual screenshots from DNP & Modbus sessions that may
assist in troubleshooting as they depict the actual settings that were required to test the board.
