OPERATION
Once the V NET™ Interface has been connected to
the computer and to the devices (and if applicable,
to the optional V NET ™ Power Supply) then there
are no further adjustments to make on the interface
itself. The indicators on the front of the unit operate
as follows
The EXT Power indicator (1) will illuminate when
DC power is being applied to the EXT Power socket
on the rear of the unit.
The NET Power indicator (2) will illuminate when
the unit is applying power to the network. This is
used for powering network-powered accessories,
and for signalling.
The USB indicator (3) will illuminate when the unit
has an active USB connection with a computer.
The Net DATA indicator (4) will illuminate when data
is being received from the network.
The Net TX indicator will illuminate when the unit is
transmitting data onto the network.
TROUBLE SHOOTING
The EXT Power indicator does not illuminate
If you are operating via RS232, you need to use the
Accessory Power Supply. Make sure this is
connected properly. Check if the power indicator on
the Power Supply illuminates. If you are operating
via USB (and there are no network-powered
devices on the network), it is not usually necessary
for an external power supply to be used, in which
case this indicator will not illuminate.
The USB indicator does not illuminate
Make sure the USB cable is plugged in both ends.
If you are using a USB hub, make sure it is capable
of providing sufficient power. You may need to use
a powered hub. Has the driver been installed?
Try unplugging the USB cable, then plugging it in
again.
If you are using RS232, this indicator will not
illuminate.
Cannot find the COM port for the USB device
Has the driver been installed?
Is the USB cable plugged in both ends?
Does the USB indicator illuminate? (Check above).
PodWare finds no devices
Have you selected the correct COM port in
PodWare?
Are the appropriate indicators illuminated?
(See above).
Make sure the network cable is not too long, is
correctly connected, and is not damaged.
Check that the Tx indicator flashes when PodWare
attempts to go online.
Will not operate via RS232
Have you selected the correct COM port in
PodWare?
You must use the Accessory Power Supply when
operating via RS232.
