Troubleshooting
An Alarm LED is Lit (Red)
In normal condition, the Alarm LED should never be lit.
However, when the Alarm LED is lit, it indicates that the
corresponding power output port is put out of function by a
hardware error, which prevents this port to power on or off.
If you see a lit Alarm LED, you should first disconnect the
device connected with it and then try to troubleshoot by
pressing several times its power button on the front-panel of
ioPower, to see if the Alarm LED still remains lit persistently.
If so, it indicates that this port is malfunctioning for good and
need technical service from your local dealer.
Port Error (unable to power on) Port Error (unable to power off)
While an alarm LED is lit, the timer setting interface on your
ioPower Management Software will also show forth the
“invalid” message and block all sequent setting possibility on
that malfunctioned port.
When a port is currently scheduled with a Timer setting for later
power on/off, its alarm LED (red) will be flashing for a reminder.
Also when you perform a firmware upgrade on ioPower, all the
alarm LEDs will be flashing while it is still in process. In these
conditions, flashing red LEDs do not indicate a problem.
Current Overloads Warning - A Flashing Numerical LED
display (Red)
If the total current loads exceed 15 AMP-- the maximum
allowable current loads of ioPower--the numerical display of
the current loads (Red) will be flashing. If you see the
flashing Numerical LED display, it means ioPower is now
suffering form a current overloads. If that is the case, you
should try to shutdown some devices to keep the current
loads within its reasonable range.
Circuit Breaker Open Due to Current Overloads
If the total current loads exceed 15 AMP, the circuit breaker
device might be activated to physically break off the internal
circuit for safety and stop the function of ioPower. To restart
the unit, just press the Power Reset button on the back panel.
Firmware Upgrade Not Successful or Firmware
Corrupted
If your firmware upgrade has not succeeded or your firmware
is somehow corrupted and could no longer function anymore,
your current loads LED display will show forth a message
such as “OP”. If you see such message on your current
loads display, please upgrade your firmware once more or
check the integrity of your firmware code.

Flash Upgrade Operation Guide
(USING WINDOWS HYPERTERMINAL)
Important Note: Beside using Windows HyperTerminal for ioPower flash upgrade, you can also use the Tools/Upgrade option
on the ioPower Management Software Menu. Please refer to the Quick Installation section on this User Guide.
The ioPower allows its user to upgrade firmware contents
whenever is needed to enhance its functionality and/or
performance. With the firmware upgrade feature, your
investment on the unit is further ensured and its life-time value
just maximized. You don’t have to buy a newer unit just to
have better features, instead you can have them all added to
your current unit with an easy flash upgrade! The correct Flash
upgrade procedure is described below. Please follow the
instructions to complete your firmware upgrade.
Flash Upgrade Procedure
Before you can perform a flash upgrade, you should have (1) a
powered-on PC with an available RS-232 port (DB9) (2) the ioPower
Unit to be upgraded, and (3) a RS-232 cable (DB9 to-DB9) connected
already to RS-232 ports on both your PC and the ioPower Unit.
AND also…..
Pease be sure to have (4) the latest flash upgrade file ( *.x ) ready on
your local computer. You can copy them from the diskette/CD-ROM
provided by the technical support or download it from available
support website.
Check the connection between the ioPower
Unit and PC
Make sure you have powered on the PC and also the
ioPower Unit before you perform the flash upgrade procedure.
Step 1. Connect your PC and the ioPower Unit using a RS-232
cable.

Once you have successfully established a serial connection,
the settings will be stored on your PC and a shortcut with the
connection’s name generated under your HyperTerminal
program menu. Next time, you can establish the connection
again simply by clicking the connection shortcut without going
over the procedure in this section again. If that is the case, just
click the connection shortcut and go right to the last section,
Flash Upgrade File Transfer .
Step 2. On your PC (which should already be connected to
your ioPower Unit with a DB9-to-DB9 RS-232 cable),
activate the Windows HyperTerminal
(Start/Programs/Accessories/Communications/Hyper
Terminal). Designate your HyperTerminal connection
with a specific name, e.g. Power Control 01.
Click OK.
Step 3. Select COM 1 or COM 2 (depending on r actual COM
port configuration). In this case, we select COM 1.
Click OK.
Step 4. Configure your port setting with the following
parameters:
Bits per seconds: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: Hardware

….and a dialog box will prompt you to select the flash
upgrade file, *.x (with a file extension name as .x). In
this case, we have our flash upgrade file as
ioPower3.0.1_040907.x (it could be any other file
name with an .x extension!). Note that since it has an
extension name other than .txt, we have to select the
“All file [*.*]” option in order to see it on the file
listing…
Then select our target file: PowerGate.hex.bin.x. And
then Click Open to begin the file transfer …..
When the file transfer is completed, you will see the
message: OK!! Please Restart on the HyperTerminal
window to tell you that Flash Upgrade process is
