5 WEB-BASED CONFIGURATION

All settings on the PowerHub can be controlled through the web-based configuration utility. To access the utility, launch a web browser on a computer that is connected to the PowerHub and enter the PowerHub IP address into the address field. The factory default IP address is

192.168.0.150. If the IP address is forgotten, refer to section 8.2 for instructions on how to reset the factory defaults.

5.1 The Status Tab

When the configuration page is loaded, the status tab will be displayed as shown below in Figure

3. The status tab displays the current state of each output, the measured input and output voltages, the internal temperature of the unit, and the fan status. This page is configured to automatically refresh once every two seconds.

PowerHubTM User Manual, Version 1.2

Figure 3: The status tab of the web based configuration utility.

The output status reflects the current state of each output. The possible states are ON, OFF, and ERR. When the output is set to the ON state, the positive output terminal is connected to the output voltage via a solid state relay. In the OFF and ERR states, the positive output terminal is disconnected from the output voltage and left floating.

Page 14

PowerHubTM User Manual, Version 1.2

The current draw and fault current limit for each output is displayed with 100mA resolution. The fault current limit can be used as a software configurable fuse to ensure that if a particular output draws higher current than expected, the output is disabled. This prevents one malfunctioning device from overloading the PowerHub and causing all outputs to be current limited.

The PowerHub output and input voltages are measured internally and displayed with 10mV resolution. These voltages are displayed as a reference, confirming the current state of the module.

The internal temperature of the PowerHub corresponds to the exhaust air temperature and is provided with 1oC resolution. If the internal temperature of the PowerHub is too high, the module will shutdown. To resume operation the input power must be cycled using the Master power switch on the front panel or by the remote enable connection.

Finally, the fan status is displayed as OK if the fans are operating as expected and ERR if one or both of the cooling fans have stalled. The fan status is only a warning to the user and the outputs will remain active until the module overheats. If a fan error is detected, the maximum operational temperature of the PowerHub will be reduced until the error is cleared.

Page 15

5.2 The Output Settings Tab

The output settings tab provides the interface to control the function of the PowerHub. The user can turn outputs ON or OFF, set the current limit, and adjust the desired output voltage.

Figure 4 displays the output settings tab.

PowerHubTM User Manual, Version 1.2

Figure 4: The Output Settings tab of the PowerHub Configuration menu.

After the output settings page is loaded, the ON and OFF radio buttons reflect the current state of each output. Clicking on the radio buttons for each output will command an on or off state. If an output fault has occurred, the output state will be displayed as OFF and the error can be reset by selecting the ON radio button for that channel. Settings will be applied only when the “Save Settings” button is selected.

Current limits can be adjusted by typing the desired value in the text box. The current limit may be entered with a 100mA resolution from 0.0 to 9.0A per channel.

Each of the 5V, 12V, and 24V PowerHub units allow the output voltage to be adjusted around the nominal output voltage of the module. The range of acceptable voltages is displayed in parenthesis next to the text box where it is entered.

The PowerHub settings can be saved in two ways: default settings or current operation settings. If saved as default settings, the saved settings will be the power-up configuration of the PowerHub. Current operation settings, on the other hand, will be lost when the PowerHub is turned off. To save the output settings as default, select the “Apply These Settings on Restart” checkbox before saving the changes.

Page 16

Pressing the “Save Settings” button will apply the output settings selection. If the user navigates to another tab before saving, the changes will not applied.

When the “Display Defaults” button is pressed, the current power-up configuration is displayed.

5.3 The Network Settings Tab

The PowerHub can be configured to be accessed as a part of any network by changing the configurations on the Network Settings tab of the PowerHub configuration menu. The factory defaults are:

IP Address: 192.168.0.150 Subnet Mask: 255.255.255.0 Gateway: disabled (0.0.0.0)

PowerHubTM User Manual, Version 1.2

Figure 5: The Network Settings configuration tab.

Page 17

PowerHubTM User Manual, Version 1.2

6 ADVANCED COMMUNICATION PROTOCOL

In addition to the web interface, the PowerHub also accepts ASCII commands over TCP (firmware v1.1 and above). The commands are made up of a command word and one or more arguments separated by spaces. A carriage return (0x0D) followed by a new line (0x0A) denotes the end of each complete command and terminates each response. Only NVT ASCII characters are valid, and any telnet option requests will trigger a WONT or DONT response (See RFC 854 for details). This permits the use of either a standard telnet client or a raw TCP connection to port

23.

The serial port may also be used for sending and receiving advanced communications protocol messages (firmware v1.2 and above). It is configured for 115200 baud, 8 data bits, no parity, 1 stop bit, and no flow control.

The following commands are available:

ON - Switches an output to the ON state.

Usage: “ON <output numbers, separated by spaces>\r\n” Example: “ON ALL\r\n” will turn all outputs on Example: “ON 1 8 4\r\n” will turn outputs 1, 8, and 4 on.

OFF - Switches an output to the OFF state

Usage: “OFF <output numbers, separated by spaces>\r\n” Example: “OFF ALL” will turn all outputs off Example: “OFF 1 5 3\r\n” will turn outputs 1, 5, and 3 off.

STATUS - Displays system status Usage: “STATUS <option>\r\n” Options:

OUT – Current output state

Example: “STATUS OUT\r\n” could return “OUT ON OFF OFF ERR ON ON OFF OFF\r\n”

IOUT – Current output amperes Example: “STATUS IOUT\r\n” could return “IOUT 1.2 0.0 0.0 0.0 8.5 0.1 0.0 0.0\r\n”

VOUT – Current output voltage Example: “STATUS VOUT\r\n” could return “VOUT 13.8\r\n”

VIN – Current input voltage. Example: “STATUS VIN\r\n” could return “VIN 55.0\r\n”

FAN – Current fan state Example: “STATUS FAN\r\n” could return “FAN OK\r\n” or “FAN ERR\r\n”

Page 18

TEMP – Current temperature in degrees Celsius Example: “STATUS TEMP\r\n” could return “TEMP 25\r\n”

IP – Current IP address Example: “STATUS IP\r\n” could return “IP 192.168.0.150\r\n”

PowerHub configuration options such as current limits, desired voltage, and network settings are currently only accessible using the web-based configuration utility.

The freely available telnet/ssh client, “PuTTY” can be used to test the PowerHub advanced

communication protocol. The necessary setup required to use the PuTTY client is outlined in the following section.

6.1 PuTTY configuration

To configure the PuTTY telnet client for testing the PowerHub advanced communication protocol, follow the steps outlined below.

PowerHubTM User Manual, Version 1.2

In the “Session” menu, enter the IP address of the PowerHub and select the “Telnet” connection type (will auto-fill Port 23), shown in Figure 6. If desired, these settings can be saved for future

use by clicking the “Save” button. Once configured, click the “Open” button to create a TCP

connection to the PowerHub.

PowerHubTM User Manual, Version 1.2

Figure 8: Front View of the PowerHub

On the front face of the PowerHub, there are indicator LEDs (1) for each of the eight outputs. These LEDs will illuminate GREEN when the corresponding output is enabled and RED if an overcurrent fault is detected on the output. If the LED is off, the output is OFF. The left most LED corresponds to output one and the right most LED corresponds to output eight.

The two fans (2) provide forced air cooling of the internal electronics and are turned on automatically anytime an output is active. Internal fan speed monitoring ensures both fans are functioning properly. The direction of air flow through the PowerHub is from front to rear.

Four mounting holes (3) on the face of the PowerHub are the primary method of attaching the device mounting brackets. These holes are threaded for a 10-32 machine screw.

The rocker switch (4) on the front of the PowerHub serves as a dual purpose as the Master ON/OFF switch and a resettable circuit breaker. This breaker interrupts all input current to the PowerHub, protecting against a short circuit condition. With the Master Switch in the ON position, the PowerHub is powered and outputs are under software control via the Ethernet interface. If the Master Switch is in the OFF position, the PowerHub is disabled and in a zero power mode.
