The C200 column gauge is an electronic gauge allowing
the connection of 1 to 8 inductive or incremental probes,
pneumatic gauge heads, sensors with analogue current o
r
voltage outputs and gauges with digital interfaces. The
extreme flexibility concerning the connection of sensors
and gauges is achieved due to the modular design and the
usage of IMBus modules.
The column gauge allows manual selection as well as
automatic selection of 1 to 8 gauges, including static and
dynamic measuring programmes and the optional classifi-
cation ( grading ) of components in up to 30 classes.
Highly sophisticated measuring programmes allow a quick
and simple calibration using 1 or 2 masters.
Two numeric displays allow indicating absolute measured
values, relative deviations or the classification of compo-
nents as well as the corresponding gauge number.
The 3-colour column display with superimposable toler-
ance marks gives a quick overview over the tolerance val-
ues of the components and is an ideal tool for controlling
workpiece characteristics in mass production.
The new Bus system of the C200 provides solutions fo
r
most sophisticated measuring applications, simply by in-
terconnecting several column gauges.

a 2.0 mm Allen key.
Further accessories, such as IMBus measuring controllers, power supply modules, measuring
modules, foot switches or adapters according to delivery note.
Please check the shipment for completeness and keep the packaging.
2.2 Fitting the base
Use the Allen key ( included in shipment )
to screw in the screws of the base and set
the column gauge on a solid base.
!!! Do not overtighten screws !!!

Instruction Manual C200
A C200 column gauge that comprises IMBus modules is configured in a fixed order. If one single C200 is to
be configured, the power supply module ( No. 1 ) always has to be fitted first, followed by the IMB-mc1
measuring controller module ( No. 2 ) and then subsequently ( starting with No. 3 ) the IMBus measuring
and interface modules in any chosen order. The fitting order of the IMBus measuring and interface modules
as a result determines the address assignment ( P1 to P8 ) of the connected sensors or measuring instru-
ments. The C200 column gauge can read in a maximum of 8 connected sensors or measuring instruments.
If several C200 are to be connected, the IMB-cas adapter cable ( No. 1 ) has to be fitted first, followed by
the power supply module ( No. 2 ), then the IMB-mc1 measuring controller and subsequently the IMBus
measuring and interface modules in any chosen order.
One power supply module can supply power to a maximum of 3 C200 column gauges in this way. If more
than 3 C200 are interconnected, an additional power supply module has to be fitted to the fourth C200 at
the latest.
Extension cables can be used to place the particular IMBus modules nearby the measuring places, if nec-
essary. Sensitive signal leads from inductive probes, for instance, or long pneumatic hoses for pneumatic
measuring configurations can be avoided in this way. The total maximum length of all IMBus extension ca-
bles must not exceed 1200 m.
2.3.2 Connecting the IMBus modules
(1) Push both red levers of the first module against the stop and rotate to the stop ( set up ).
(2) Connect modules.
(3) Rotate back both red levers to lock the modules while pressing them together.
Follow steps (1), (2) and (3) to connect the IMBus modules one after the other.
The following table indicates the installation sequence of the IMBus modules.
Position 1 is the bottom position later on, and is screwed to the base of the C200 column gauge.
!!! Important : The bottom IMBus module must be equipped with bolts to do so.

Instruction Manual C200
Important :
Should an IMBus module already be equipped with bolts ( e.g. IMB-ps2 when using an IMB-cas
adapter cable ), please replace the bolts with 2 cross-recessed screws SH-UNC / 4-40*9.5
( included in shipment ) in order to enable connecting of modules.
2.3.3 Fitting of bus terminator
Prior to inserting the modules into the column profile, the bus terminator connector is attached to
the vacant port of the last module and screwed to it.
If the last module has not been fitted with bolts to fix the terminator connector, both cross-recessed
screws will have to be removed and replaced with bolts.
The bolts are included in the shipment !!!
About the bus terminator :
The purpose of the bus terminator is to terminate the bus lines electrically, to seal the open port,
and to provide information on the function and the power supply of the column gauge.
The “VCC” LED lights up when the power supply to the column gauge is secured. The “VCC” LED
will be extinguished, if the power supply module has been overloaded due to external consumers,
such as digital probes with high current consumption, or as a result of voltage drops due to long
IMBus extension cables. The IMBus design, however, allows adding power supply modules
between any IMBus gauging and interface modules at will, to compensate voltage drops.
The “RUN” LED lights up, when the self-test of all IMBus modules has finished successfully.
The “RUN” LED will not light up and will thus signal that the IMBus could not be completely
checked, if more IMBus modules have been fitted than can be addressed by the column gauge.
Note : The “RUN” LED will not issue an error message in this case, but instead signalises the
incomplete self-test of modules that cannot be addressed.

11
Instruction Manual C200
2.3.4 Fitting IMBus modules into the C200 column gauge
Once the IMBus modules have been connected, they are slid into the C200 column section as a
package from the top and are then screwed to the column base using both cross-recessed screws.
!!! Do not overtighten screws !!!
If modules have already been fitted into the C200 column and additional modules are to be in-
stalled, then all previously fitted modules must be removed first.
Loosening and removing previously fitted IMBus modules :
The IMBus modules are screwed to the C200 base by means of 2 screws. At first both cross-
recessed screws must be loosened by using a suitable screwdriver in order to remove the fitted
modules. Two lock washers keep the screws in place and they remain in the C200 base. The
base does not need to be removed. Once both screws have been completely loosened, the
IMBus modules can be slid to the top of the column and removed from it.
After removal of the initially fitted modules, additional modules
can be added. Afterwards the complete module package can be
slid into the C200 column section. Finally the module package
is screwed to the column base.
2.3.5 Fitting of C200 column cover.
Place the column cover on top of the C200 and fix with two Allen screws ( M3 x 8).
!!! Do not overtighten screws !!!

Instruction Manual C200
2.4 Measuring input addresses
The measuring inputs are referred to
as P1 to P8 for subsequent programming.
The bottom measuring input is always
P1. It is possible to connect more than 8
measuring inputs, the C200 column gauge,
however, can only address and read in the first
8 inputs.
Note :
When connecting further column gauges via
IMB-cas adapter cables, the measuring inputs
( P1 to P8 )of the first column gauge are also
available at the subsequent column gauges
and are referred to as the same addresses.
Therefore, there is no complex behaviour to pay
attention to when programming.
When connecting several column gauges, please take
into account the following facts:
A further measuring module in a series of column gauges
will interrupt the connection to the previous measuring
modules, and make available its inputs for the subse-
quent column gauges, including the one it is fitted into.
See also example 2 on page 14 of this manual.
Note for wireless application :
The IMB-rf1 modules allow the reception of measure-
ment values from 1…8 IBRit-rf1 radio modules. There-
fore each IMB-rf1 module contains eight channel num-
bers.
Each channel can be assigned to one of the 1...120
addresses of an IBRit-rf1 radio module.
When you use an IMB-rf1 module together with other
IMB-modules in one C200, then you must install the
IMB-rf1 module as the last module of the C200 ( upper
position ). Because the C200 supports only eight chan-
nels and the IMB-rf1 has already eight channels, all other
IMB-modules behind the IMB-rf1 module are ignored by
the C200.
The programming of IBRit-rf1 radio modules and the
address assignment of the 1…120 IBRit-rf1 module
addresses to the 1…8 IMB-rf1 channels can be done
by using the PC software C200_PC (provided by IBR
free of charge ). The settings are made in the menu
“Programming of IMBus modules”.

2.5 Connecting several column gauges
IMB-cas type adapter cables are utilized to connect several column gauges.
The adapter cables fulfil two tasks :
1.) Transferring the supply voltage from the first column gauge to the next.
One power supply module can supply power to a maximum of 3 column gauges, depending on the connected
probes, sensors and measuring instruments. The number of column gauges decreases, if the current con-
sumption of the connected measuring instruments exceeds 200 mA. As shown in Example 2, power supply
modules can be added at will. Each module performs the function of supplying power up to the next power
supply module.
2.) The measuring inputs P1 to P8 of the first column gauge are made available for the sub-
sequent column gauges.
The measuring inputs are passed on to the subsequent column gauges via the IMB-cas adapter cables. The
data flow direction within the adapter cable is always from the thinner adapter housing towards the thicker
adapter housing. A further measuring module in a series of column gauges will interrupt the connection to the
previous measuring modules, and make available its inputs for the subsequent column gauges, including the
one it is fitted into. See also example 2 on page 14 of this manual.
Note : Foot and hand switches can be cascaded in order to synchronize several column gauges ( e.g. for dynamic
measuring ). See chapter 2.7 for more detailed information.
Mechanical connection of column gauges : The housing connector underneath the IMBus column
cover serves to link together the column gauges. Take
the connector out of its storage and screw it together
with the column cover.
!!! Do not overtighten screws !!!
Example 1 : connecting 3 column gauges
The three-column gauges are linked together via
two IMB-cas adapter cables. The adapter cables
are always fitted in the first position ( bottom slot ),
whereat the thinner adapter section is always
fitted to the first column gauge. When using
several IMB-cas adapter cables make sure that
the thinner adapter section is fitted in the first
position, with the thicker adapter section of the
arriving cable directly above it. The power supply
module of the first column gauge supplies all
three column gauges with power. The measure-
ment inputs P1 to P4 are available at all three
column gauges.

14
Instruction Manual C200
2.6 Power supply connection
There are three modules available from the IMBus series to supply the column gauge with power :
1. IMB-ps2 : ( Part No. F121 020 )
Switched-mode power supply (SMPS) featuring wide range
voltage input from 100 to 240 VAC, 45 to 60 Hz
2. IMB-dc1 : ( Part No. F121 040 )
DC to DC converter for input voltage range from 9 to 32 VDC
3. IMB-acc : ( Part No. F121 030 )
Rechargeable battery (accu-pack) module for battery-operated systems.
The module allows quick battery replacement. Rechargeable batteries
with capacities of 1850 / 4000 and 5500 mAh are available.
( Example : C200 with 2 inductive probes and a 4000 mAh battery pack
can operate for approx. 12 to 15 hours )
First read the sticker information on the fitted power
supply module and then check whether the module is
suitable for your mains voltage respectively DC voltage.
Use the enclosed power cable to connect the IMB-ps2
to the mains outlet.
Important !!! Insert device plug into grounded
outlet only
Example 2 : connecting 5 column gauges
The five column gauges are linked together via
four IMB-cas adapter cables. The cables are
always fitted in the bottom positions, as shown
in the illustration. The measurement inputs are
passed on from the thinner adapter section to-
wards the thicker adapter section. When using
several IMB-cas adapter cables make sure that
the thinner adapter section is fitted in the first
position, with the thicker adapter section of the
arriving cable directly above it. The power
supply module of column 1 supplies
columns 1, 2 and 3 with power. The power
supply module of column 4 interrupts the further
power supply from column 1 and supplies col-
umns 4 and 5 with power. The measuring mod-
ule in column 1 makes available the measure-
ment inputs ( P1 to P4 ) for columns 1 and 2.
The measuring module in column 3 interrupts the
connection to the measurement inputs from col-
umn 1 and makes available its own measure-
ment inputs at columns 3, 4 and 5.

15
Instruction Manual C200
2.7 Connecting a foot or hand switch
The foot or hand switches are connected to the Sub-D ports Ft1 and Ft2 of the IMB-mc1 measuring
controller. Foot and hand switches can be cascaded in order to synchronize several column gauges
( e.g. for dynamic measuring ) by using a foot or hand switch connected to the Ft1 or Ft2 connector.
The Y-Adapter ( Part No. F121 190 ) can then be used for cascading.
A third foot or hand switch ( Ft3 ) can be connected directly to the IMBus. An IMB foot or hand switch
is used in order to do so. It provides an IMBus connecting part and can be inserted into the IMBus at any
place behind the IMB-mc1 ( see illustration below ).
The functions of the foot or hand switches can be configured in the “BASIC SETUP”
menu ( L3 -L5 ).

2.11 Connection of probes, air plug gauges, sensors and measuring instruments
The modular design in conjunction with the IMBus measuring and interface modules makes it possible
to connect virtually any probe, pneumatic gauge head, sensor or measuring instrument to the column
gauge. A maximum of 8 measuring inputs can be handled by the C200. It is possible to connect more
than 8 inputs, however, the additional inputs are ignored. The RUN LED on the bus terminator connector
does not light up, if the surplus IMBus modules cannot be completely addressed ( see page 10, Information
on Bus Terminator ). The IMBus measuring and interface modules can be combined in any order and allow
the simultaneous connection of different types of sensors ( inductive, digital, pneumatic, etc. ). For an over-
view of IMBus measuring and interface modules see chapter 2.12.
Important !!! Reliable measurements can only be guaranteed,
if the connections have been screwed tight,
so that the contact to the probe shielding is good.
Example 1 : Connection of inductive probes
Prior to connecting the probes, check whether the
probe types correspond to the type designations
listed on the IMBus module ( IMB-im1 / 2 / 4 / 8 ).
Secure the connectors by screwing them tight.
Example 2 : Relocation of IMBus measuring and interface modules
IMBus extension cables can be utilized to perfectly adapt
measurement configurations with IMBus modules to
spatial requirements. The extension cables can be used
to interconnect any modules and reach a maximum length
of 1200 m. Use genuine IMBus extension cables and bus
terminators only !!!
Note :
The IMBus is based on an RS485 interface and has been
developed for the demands of rough industrial use.

The example depicts a C200
configuration for connection of
2 inductive probes ( IMB-im2 ),
2 incremental probes with
1Vss output ( IMB-dm2 ), one
pneumatic plug gauge ( IMB-ae1 ),
2 Mitutoyo dial gauges ( IMB-mi2 )
and one calliper gauge ( Sylvac, Tesa,
Mahr, etc. ) with Opto RS232 output
( IMB-sm1 ).
The column gauge allows the connection
of up to 8 pneumatic measuring converters
IMB-ae1. An 8-by-6 mm hose connector
( 8 mm -> outer diameter; 6 mm -> inner
diameter ) is used to establish the com-
pressed air supply. A hose piece with a
length of 35 mm is required in order to
pneumatically interconnect two IMB-ae1
modules. Use dry, oil-free and filtered
( 5 µm ) compressed air only, ranging from
2.6 … 2.8 bars ( 39 … 42 psi ) to connect
to the IMB-ae1 measuring converters
( recommended air pressure ).

2.12 IMBus modules at a glance
The modules shown below provide an overview of IMBus measuring and interface modules that can be
connected to the C200 column gauge.
!!! For more information see IMBus series !!!
2.13 Power on / Self-test
Every time the column gauge is switched on, a self-test will automatically be performed in order to check
all system components. If an error is detected during the self-test, the numeric display will indicate an er-
ror message.
If the display remains dark, after the C200 column gauge was switched on, check both, the VCC and
RUN LEDs on the bus terminator connector.
Both LEDs must be lit !!!
VCC - LED is lit if the supplied voltage is within allowed tolerance values.
RUN - LED is lit if the internal self-test for all modules has finished successfully.
See chapter 2.3.3 for more information
A display test routine runs subsequently, during which all display elements are switched on, one after the
other. This enables the user to check the function of the display elements. Once the column test has been
completed, information on the release of the software is shown on the six-digit numeric display.
Note : The RS232 interface of the column gauge is not active while the self-test is running.

3. Programming the column gauge
The rotary encoder on the front panel is used to make all settings and carry out any programming.
During programming the user is guided through the individual menus, step by step, and prompted by the
LED and numeric displays. The programming procedure follows a logic structure and becomes self-
explanatory after studying it briefly.
Abbreviations used :
Encoder : Rotary encoder with pushbutton function
CW : Turn rotary encoder clockwise
CCW : Turn rotary encoder counterclockwise
3.1 Encoder functions
Turning the encoder By turning the encoder clockwise ( CW ) in the Measuring Mode, you can switch
to the Calibration Mode or the Programming Mode.
In the Calibration or Programming Mode, the flashing value or function can be
altered by turning the encoder.
CW - increases the value or moves to the next function.
CCW - reduces the value or returns to previous function.
Pushing the encoder By pushing the encoder button in the Measuring Mode, the function selected
in the Basic Setup is executed.
Programming is carried out in the “BASIC SETUP” menu, section “L2” - Encoder key
function in measuring mode.
Push the encoder button in the Calibration or Programming Mode to accept the
programmed value or the flashing setting respectively.
Push and hold The six-digit numeric display indicates the column display range in the
for > 2 sec. Measuring Mode.
The programmed value of the corresponding, flashing menu LED is displayed for
1 second in the Programming Mode.
This is only valid for the values of “NOMINAL SIZE” and “MASTER VALUE”.
Pushing and turning Switches to and from the activated gauges C1 to C8 in the Measuring Mode.
The gauges ( C1 to C8 ) are activated in the “BASIC SETUP” menu, section “L0” –
Activate / deactivate gauges.
3.2 Foot and hand switch functions
The column gauge allows connecting up to 3 foot or hand switches. The functions of the particular
switches can be assigned in the “BASIC SETUP” menu, sections L3 to L5.
