General Information:
·
The Bobe HF-MS System provides
computer aided, cable-free measuring by replacing the cable connection between
the measuring device and the interface box or PC by radio transmission.
Depending on the environmental conditions you can bridge a maximum of 80m in
the open air and approx. 10m-15m in a hall.
·
The system currently exists for all measuring devices with a Digimatic
interface and default OptoRS232 interface and for the Mahr EX 16 caliper or
compatible measuring devices (for devices with an RS232C interface upon
request). You can operate a maximum of 99
measuring devices concurrently in a system. A number is allocated to each
measuring device allowing you to identify the individual measured values
correctly. (With receiver version 1.xx and sender version 1.xx, 2.xx or 3.xx
you can operate only eight measuring devices.)
·
A system consists of a receiver (HF-MS-M) which is connected
directly to the PC, and at least one sender
(HF-MS-Sx) which is connected
directly to the measuring device. The transfer of measured values is
triggered by pressing the data button on the measuring device or sender
(depending on the measuring device type). The transfer of measured values from
the receiver to the PC can be set by an interface with MUX10, MUX50 or Bobe
command set and has to be evaluated correctly by the PC software.
·
The radio frequency is set to either
(1) 868,300MHz, (2) 869,750MHz, (3) 869,2625MHz, (4) 869,800MHz or (5)
869,925MHz. The type plate shows what frequency your system uses. Make sure
that only devices with the same frequency work together and that no foreign
device sends signals on this frequency in a vicinity of 300m. Otherwise the
data transfer might be faulty.
Caution:
Read the
section First Operation before you
start using the system for the first time.
Controls:
Antenna Socket
Jack for the antenna supplied.
Status LED’s
The three status LED’s indicate the operating status
of the HF box.
The green LED on the right is lit as long as the box
is switched on.
The yellow LED in the middle is lit when a radio
transfer takes place.
The red LED on the left is lit when a data
transfer was faulty.
Status Buzzer
The buzzer confirms every data
transfer. If the data transfer is correct, two tones sound.
By removing the jumper inside the device the buzzer can turned off.
USB Interface
Socket
for the USB cable supplied for connection to the PC.
First Operation
Step 1: Connect the antenna and choose the location.
First
connect the antenna supplied to the receiver box (HF-MS-M). Slide it on the
correct socket and turn it to lock it in place.
Choose a suitable location for the radio transfer. Always choose the
biggest possible distance to other electronic instruments and metal objects. If
you encounter transfer problems, it might be sufficient to change the location
of the HF box by a few centimeters.
You can also fix the HF box to the wall to achieve a higher location. In
any case, the distance between the receiver and sender must not exceed 80m in
the open air and approx. 10-15m in the hall. In separate rooms the distance
might have to be shorter.
Step 2: Connect the receiver (HF-MS-M) to the mains
and PC.
Use the USB cable supplied to connect the receiver (HF-MS-M) to a free
USB port of your PC. The receiver gets its power via the USB cable, so it is
always turned on. When you connect the receiver to your PC for the first time,
you will be asked to install its driver.
Please read the manual for driver
installation on the CD!
Step 3: Connect the sender (HF-MS-Sx).
If the
sender is not pre-mounted to the measuring device, you have to connect it to
the measuring device. Turn off the measuring device and connect the sender
directly to the data output of the measuring device as you would with a normal
data cable. You can now use double-sided tape to attach the sender to the back
of the measuring device. Open the lid on the back and insert the battery
supplied. Make sure that the polarity is correct: the face marked with + has to be
turned away from the holder, i.e. you must be able to read it. Every time you
insert a battery the version number of the sender firmware is transferred as a
measured value, provided you reset the sender (see “Operation with Several
Measuring Devices” for more information).
Step 4: Switch on and use the HF-MS System.
Now that you have connected the receiver and sender you can switch on
the measuring device. Start your PC software which should receive the measured
values and configure all necessary settings to receive values through the
Virtual COM Port (VCP) that the receiver is connected to (See also Bobe-USB-Box
driver installation on the CD). The measured value can be in the MUX10,
MUX50 or Bobe format. Your PC software must be set as if an interface with the
corresponding command set were connected.
The output format is determined by solder bridges inside the sender. The
format should have been set by Bobe according to your requirements. If you have
to change the setting, consult an expert. The following illustration shows how
to set the solder bridges:
solder bridge J4 bridged: Bobe format
solder bridge J3 bridged, J4 open: MUX50
both open: MUX10
The green LED on the receiver signals that the device is switched on.
The yellow and green LED have to be off. If this is the case, the receiver is
ready to receive data, or in other words, the sender can now send data. The
data transfer always takes place from the sender.
Measure a value and press the data button on your measuring device (with
default OptoRS232 you have to press the button on the sender) to transfer the
value. (If need be read the operating instructions of your measuring device).
When the receiver receives the value correctly, two tones sound, and the value
is forwarded to the PC.
Only press the data button again once the measured value has been
transferred to the PC and no tone can be heard anymore (after approx. 2
seconds).
Explanation of the
status LED’s and status buzzer:
When two tones sound and the yellow LED is lit briefly, the measured
value was transferred correctly.
When the red LED is flashing, the measured
value was transferred incorrectly, and no measured value was transferred to the
PC. Read the section "Transfer Problems“.
When no tone is audible and neither the red nor the
yellow LED is lit briefly despite pressing the data button on the measuring
device or sender (depending on the type), no data was transferred. Read the section
"Transfer Problems“.
Note on Tesa (capa µ)
Measuring Devices
To increase the life of the battery in the sender, the
sender usually turns on only for the duration of a measured value transfer.
However, for technical reasons the sender of Tesa (capa µ) measuring devices
only turns off after 10 minutes if no new measured value was transferred in the
meantime. This corresponds to the duration after which the measuring device
turns itself off if it hasn’t been moved. After switching on the measuring
device again, you have to press the data button once to turn on the sender.
This does not transfer a measured value. Press the data button again to
transfer a measured value.
If you move the caliper without pressing the data
button thereafter it can happen that the sender has already switched itself off
although the caliper is still on. Pressing the data button does not transfer
any measured value, but simply switches on the sender again. You won’t hear any
confirmation beep from the receiver. Press the data button again to send the
measured value.
Note on Measuring
Devices with the RS232C Interface
To increase the life of the battery in the sender, the
sender usually turns on only for the duration of a measured value transfer.
However, for technical reasons the sender of RS232C interface measuring devices
only turns off after 30 minutes if no new measured value was transferred in the
meantime. Press the data button once to turn on the sender. This does not
transfer a measured value. Press the data button again to transfer a measured
value.
If you encounter transfer problems first make sure
that all devices are switched on. If this is the case, choose a different
location (see step 1) and test the radio transfer using a small distance. Press
the data button on the measuring device or sender to trigger the radio
transfer.
If the receiver does not issue two tones and if the
red LED is not lit, no carrier signal is detected. Make sure that the battery
was inserted correctly into the sender (see step 3) and that the connection
between the measuring device and the sender was established correctly.
If you continue to encounter transfer problems and if
you have tried several locations (see step 1), then make sure that no other
sender works with this frequency. If the red LED on the receiver is lit
although you did not press the data button, a carrier signal from a different
device was received. Other devices which are not used for radio transfer might
also interfere. Try to localize and remove these devices.
If the receiver issues two tones, the value was
received correctly. If it does not appear in the PC software, the connection
between receiver and PC is faulty or the PC software has been configured
incorrectly.
To operate several measuring devices in one system
simultaneously, you have to store a measuring device number in the sender. This
number will be sent with every measured value transfer. The number corresponds
to the canal number as it is known from cable-connected interfaces. You can
choose measuring device numbers from 1 to 8 or from 1 to 99. To store the
number:
Requirement: sender—firmware version 1.xx or 2.xx, receiver—firmware version 1.xx to 3.xx
Set the measuring device to a value so that the digit directly
before the point reflects the desired number. With Mahr Extramess 2000/2001
the digit directly after the comma must correspond to the desired
number. The other digits are not relevant. Fix the measuring device (if
possible) so that the value does not change. Remove the battery from the sender
and briefly insert it into the holder the wrong way round. This will reset the
sender electronics, but not short-circuit the battery. Turn the battery the
right way round and press the data button on the measuring device or sender
within 2 seconds. This will save the digit before (or after) the point as
measuring device number. As it is the case every time you insert a battery, a
measured value will not be transferred, but the version number of the sender
firmware will be transferred as a measured value. The computer will receive a
string with preceding measuring device number, e.g. 02A+0001.010CRLF
for measuring device 2 and version 1.01
Requirement: sender—firmware version 3.xx or 4.xx, receiver—firmware version 4.xx
Set the measuring device to a value so that the digit directly
before the point reflects the tens digit of the desired number and the
digit directly after the point the units digit. With Mahr Extramess
2000/2001 the two digits directly after the comma must correspond to the
desired number. The other digits are not relevant. Fix the measuring device (if
possible) so that the value does not change. Remove the battery from the sender
and briefly insert it into the holder the wrong way round. This will reset the
sender electronics, but not short-circuit the battery. Turn the battery the
right way round and press the data button on the measuring device or sender
within 2 seconds. This will save the two digits before and after (or both
digits after) the point as measuring device number. As it is the case every
time you insert a battery, a measured value will not be transferred, but the
version number of the sender firmware will be transferred as a measured value.
The computer will receive a string with preceding measuring device number, e.g.
63A+0003.010CRLF for measuring
device 63 and version 3.01
Use the device only in dry rooms.
Unplug the device before opening the
cover.
