2. Safety Hints
STOP
Attention!
Fitting or exchanging of an interface must not be
made unless the oscilloscope is switched off and
not connected to line (mains).
STOP
Attention!
During operation the interface opening must be
closed.
STOP
Attention!
All interface connections are galvanically connected
to the scope.
STOP
Measurement at high potentials is prohibited and
endangers the scope, the interface and all equip-
ment connected to the interface.
If the safety rules are disregarded, any damage to HAMEG In-
struments GmbH products will void the warranty. Consequently
HAMEG Instruments GmbH will not take any responsibility for
damage to people or equipment of other make.
3. Interface Description
HO730 is a DUAL Interface that can be used either as an Ether-
net or as a USB 2.0 / 1.1 Interface. It is used with the HAMEG
CombiScopes HM1008 and HM1508 for data transfer and
oscilloscope control. Only one function (Ethernet or USB) - not
both at the same time - can be activated (see item 6 “Interface
Selection”).
3.1 Ethernet
The interface is equipped with an Ethernet type RJ-45 connector
according to IEEE standard 802.3. For the direct connection
with a host (PC) or indirect connection over a SWITCH, a doubly
protected network cable (e.g. CAT.5, CAT.5e, CAT.5+, CAT.6 or
CAT.7) is required, equipped with an Ethernet plug type the
RJ-45 at each end. Either an uncrossed or a crossed network
cable (cross over cable) can be used.
3.2 USB
The interface is equipped with a Type A USB female connector.
For direct connection with a host controller or an indirect con-
nection via a USB hub, a USB cable is required, equipped with
Type B male connector one end and a Type A male connector
at the other..
4. Oscilloscope Firmware
4.1 It is absolutely necessary to check the oscilloscope fi rmware
version before fi tting the Interface HO730. The fi rmware
version already on the scope is displayed after switching
on if “Quick Start” is off. The “Quick Start” function can
be changed after pressing the SETTINGS pushbutton and
calling “Misc.”. Alternatively the fi rmware version of the
oscilloscope can be found in the menu „Software“ by ope-
ration of the PROBE ADJ key
>
menu „Information“
>
menu
„Software“ (MC-Version:).
4.2 If the fi rmware version is 04.000-yy.yyy or higher, continue
the interface fi tting as described under item 5 (Interface
Fitting Instruction). In the case of fi rmware versions below
04.000-yy.yyy, HO730 will not be recognised and a fi rmware
update is required as described under item 4.3.
4.3 In case of a fi rmware version below 04.000-yy.yyy, please
download the current fi rmware at www.hameg.com from the
Internet and update the oscilloscope. The fi rmware can be
found and downloaded under: Products
>
Oscilloscopes
>
(oscilloscope type)
>
Software/Firmware (below the oscil-
loscope picture)
>
Firmware_HMxxx_Vxxx.zip.
After receiving the current fi rmware and its installation instruc-
tion, the fi rmware installation must be done via the RS-232
interface HO710 or the RS-232 port of the interface HO720. If
the current fi rmware is installed, future updates can also be
made over the USB port of the interface HO730.
