1. 66061 JBUS/Modbus Card (Galaxy 3/4/5k, PW and Epsilon STS)

1. Configure the slide witches on the 66061 board first.
   1. SA1 switches should be set to “ON” position which places the card in program mode.
   2. SA2 switch need to be programmed per wiring configuration
      1. 2-wire without polarity and termination (only one device attached to the EGX or last device in the line)
         1. Switches 3, 4 and 5 set to “ON” position
      2. 2-wire without polarity and without termination (more than one device and not the last in line)
         1. Switches 4 and 5 to “ON” position
2. Communication port configuration:
   1. Connect to the RS232 communication port which is the one next to the green LED or on the right when reading the card part number 66061 (when installed in some UPSs the card is upside down).
   2. Open a terminal program like HyperTerminal and enter a name for the new connection.
      1. Select correct communication port on your laptop.
      2. Change port settings to the following:
         1. Baud rate:  9600
         2. Data bits:  7
         3. Parity:  Even
         4. Stop bits: 1
         5. Flow control:  None
         6. Click OK when done
      3. Using a pencil, Pen or small tool press and hold down the reset button for 6 to 7 seconds until the green LED starts to blink again.
      4. Back in HyperTerminal press the “Return” key a few times until you see CDE->
      5. Below are the commands available
         1. Display current configuration:   L
         2. Set Baud rate:  V
         3. Parity settings:  P (enter 0 for None and 2 for Even)
         4. Slave number setting:  E

2. 2. 6. For EGX you only need to change the baud rate and slave address.
         1. Press “L” and then press the enter key to verify current configuration
         2. Verify that the Parity is set to “None” (without parity).  If not set to “None” use the “P” command described above to change it to “None”.
         3. Press “V” and press the enter key, Enter9600 for baud rate then press enter key
         4. Press “E” and enter slave address 20 (hexadecimal value) which the card will display 32 (decimal value).
         5. Press “L” and then press the enter key to verify configuration is correct 9600, none and slave address 32 decimal.
         6. Exit HyperTerminal and press the reset button on the 66061 for a second or two to reset the card.
         7. Configuration of the 66061 is completed
   3. PUTTY configuration as HyperTerminal is no longer part of Windows.
      6. Click on Serial under Connection – at the bottom of screen.
      7. Change port settings to the following:
         1. Serial line to connect to:  Type in you comport
         2. Speed (baud):  9600
         3. Data bits:  7
         4. Stop bits: 1
         5. Parity:  Even
         6. Flow control:  None
      8. Next click on Session at the top of the screen.
         1. Click on Serial which Serial line and Speed should be populated automatically.
         2. I suggest entering a name under Saved Sessions and click on Save so you can load for future use.
         3. Click on Open button and a new screen should appear like a normal terminal program.
      9. Using a pencil or small device, press and hold down the reset button for 6 to 7 seconds until the green LED starts to blink again.
      10. Back in HyperTerminal press the “Return” key a few times until you see CDE->
      11. Below are the commands available
          1. Display current configuration:   L
          2. Set Baud rate:  V
          3. Parity settings:  P (enter 0 for None and 2 for Even)
          4. Slave number setting:  E
      12. See the second above “vi For EGX you only need to change the baud rate and slave address.” On how to program the JBUS/Modbus card.
3. Wiring
   2. EGX150 RJ45 pin 4 goes to pin 5 on the 66061 and EGX150 pin 5 goes to pin 9 on the 66061.

1. 2. EGX150 cable adapter wiring, pin 4 (TX-) goes to pin 5 on the 66061 and EGX150 pin 5 (TX+) goes to pin 9 on the 66061.

2. EGX 150configuration and validation:

1. Connect network cable to EGX150 and laptop.
2. To connect to the EGX the IP address needs to be determined.  The default IP address is 169.254.YY.ZZ which YY and ZZ are determined by the last 2 bytes of the MAC address.
3. Example for MAC address:  00-B0-D0-86-8B-D4 is to use BB-D4 for YY (BB) and ZZ (D4).
4. Convert the 8B and D4 from hexadecimal to decimal using a calculator.  8B is 139 and D4 is 212 so the IP address for the device is 169.254.139.212.
5. Laptop network configuration required to communicate to the EGX150.
   1. Use an IP address that does not conflict with the EGX150 for example you can use 169.254.139.211 (subtract or add to the last digit) with a class B subnet mask (255.255.0.0).  Gateway can be left as zeros or unconfigured as it is not required for peer-to-peer networking.
6. EGX150 login credentials.  Username:  Administrator / Password:  Gateway
7. Launch a web browser and enter the IP address of the EGX150 in this document’s example is 169.254.139.212.
   1. The “Serial Port Settings” need to be configured to match the 66061 JBUS/Modbus card.
      1. Click on the “Configuration & Settings” tab which located on the top section of the web page.
   2. Next click on “Serial Port” under “Network Configuration” on the left side of the web page.
   3. In the center section of the web page the following settings need to be verified or changed.  Click Apply Changes button when completed
      1. Mode (Device reboots on change):  Master (default)
      2. Physical Interface:  RS485 2-wire (default)
      3. Transmission Mode:  Automatic (default)
      4. Baud Rate:  9600 (change from 19200)
      5. Parity:  None (change from Even)
      6. Stop bits:  1 (change from Auto)
      7. Termination:  Disabled (change from Enable)
      8. Biasing:  Enable (default)
      9. Response Timeout:  6000 milliseconds (default)

8. Validate communications to the 66061 JBUS/Modbus card.
   1. Click on Diagnostics then Communications and Read Device Registers
   2. Configure the following items
      1. Local ID (slave address of the 66061)
      2. Starting Register (Modbus register in the table below)
      3. Number of Registers (1-10) If UPS set to 4 but if STS set to 3.
   3. Below are the Modbus registers to use by product.  The best registers are Frequency as they should be 60 (on some product it will have three digits so 600 instead of 60 – just drop the last digit).  Keep in mind that the 66061 Manual registers are JBUS, and most be converted to Modbus.  Example JBUS 100 (hex) converted to 256 (decimal) plus 1 for the Modbus offset which is Modbus 257.

1. 4. Below is an example.  This is example is a G5k in bypass, so Mains and Inverter are zero, but Mains 2 Output frequency is 59.  If you receive time out recheck the configurations above.

5. Configuring your laptop to communicate with the EGX with default IP address of 169.254.0.10
   1. Access Network connections
   2. Right click on your local area connection and click on “Properties”.
   3. Double click on “Internet Protocol (TCP/IP)
   4. Click on “Use the following IP address”
   5. IP address:  Enter 169.254.0.15
   6. Subnet mask:  Enter 255.255.0.0
   7. Default gateway:  Leave blank
   8. Click on “OK” twice to get to back to Network connections.
   9. Connect a network cable from the EGX to your laptop
   10. Enter the EGX IP address in your web browser and it should load.

6. SCADA System
   1. Integrator should be able to poll the UPS(s) through the EGX via the IP Address and Slave Address.

7. Troubleshooting:
   1. Verify wiring and flip wires if needed.
   2. Verify EGX configuration.
   3. Use a RS485 to USB converter and communicate directly to the 66061 card to eliminate wiring, noise or EGX configuration/defect.
   4. If you use the JBUS registers in the manual as they are you will get a communication issue.  Most convert the JBUS registers to Modbus.
