2.12.1
Introduction
CNC machine tools which are using Renishaw
spindle probes with radio signal transmission
for workpiece inspection, or tool setters with
radio signal transmission, require a Renishaw
radio machine interface (such as the RMI-Q)
for signal transmission. The RMI-Q, which acts
as a combined radio transceiver and machine
interface, converts signals from the RMP into
voltage-free solid state relay (SSR) and driven
outputs for transmission to the CNC machine
controller.
The RMI-Q is designed to be mounted within
the machine’s working envelope.
Application of the RMI-Q enables individual
radio turn on and subsequent operation of up to
four separate 2nd generation RMPs, permitting
numerous combinations of radio inspection
probes and/or radio tool setters to be used on the
same machine tool.
RTS, and other 2nd generation RMPs, are easily
identified by a 'Q' marking. 1st generation RMPs,
which do not have the 'Q' marking, may also
be used with the RMI-Q. However, in machine
tool applications where more than one RMP
is required, it is recommended that only 2nd
generation RMPs are used. Should there be a
requirement to use a 1st generation RMP with the
RMI-Q, it is necessary that any additional probes
are 'Q' marked 2nd generation RMPs
RMI-Q basics
Optimum communication performance between
the RMI-Q and the RMP is achieved when the
RMI-Q is aligned towards the RMP in operation.
Other alignments are permissible with negligible
reduction in communication performance.
However, alignment of the RMI-Q away from the
RMP should be avoided as this may result in
reduced communication performance.
CAUTION RMI-Q operation of up to four
separate RMPs is different to 'multiple probe
mode' which is a function of the RMP that enables
individual application of multiple probes but does
not use radio turn on.
Power supply
The RMI-Q can draw its supply from the CNC
machine tool's 12 Vdc to 30 Vdc supply and
present a peak load of up to 250 mA during turn
on (typically 100 mA from 24 V).
Input voltage ripple
The input voltage ripple must not cause the
voltage to fall below 12 V or rise above 30 V.

NOTES:
The 'PROBE STATUS' LED is always illuminated
when power is present at the RMI-Q (as the
RMI-Q does not incorporate a separate ‘power
present’ indicator).
All LEDs report the status of the partner RMP. If
there is no partner in range, or the partner is off,
then the 'PROBE STATUS' and 'ERROR' LEDs
will illuminate red. The 'LOW BATTERY/START'
and 'SIGNAL' LEDs will be off.
When the RMI-Q is powered on it will enter
the acquire partner mode. This is indicated by
a flashing green 'SIGNAL' LED (no change in
outputs). After ~60 seconds it will switch to its
normal mode listening for its partner.
The conditions shown by the 'LOW BATTERY/
START', 'PROBE STATUS' and 'ERROR' LEDs
are the same as those present on the electrical
signal outputs.

RMI-Q basics
RMI-Q inputs
Machine start inputs (P1, P2, P3, P4):
'Machine start' inputs are configurable as a level
or pulsed signal.
Level 10 to 30 V (2.4 mA at 24 V)
When input is active, probe is
switched on.
Pulsed 12 to 30 V (10 mA at 24 V)
Probe toggles from being switched on/
off. The minimum pulse width is 10 ms.
P1 machine start wires (white +ve and brown -ve).
P2 machine start wires (pink +ve and brown -ve).
P3 machine start wires
(white/red +ve and brown -ve).
P4 machine start wires
(white/blue +ve and brown -ve).
RMI-Q outputs
There are five outputs:
• Probe status 1 (SSR).
• Probe status 2a
(5 V isolated driven skip).
• Probe status 2b
(driven at power supply voltage).
• Error (SSR).
• Low battery (SSR).
All outputs can be inverted by using switches SW1
and SW2 - see page 2.8 'Switches SW1 and
SW2'.
Probe status 1, Error, Low battery (SSR):
• ‘On’ resistance = 50 ohm max.
• Load voltage = 40 V max.
• Load current = 100 mA max.
Probe status 2a (5 V isolated driven skip):
• Load current = 50 mA max.
Output voltages
• Sourcing = 4.2 V min at 10 mA.
= 2.2 V min at 50 mA.
• Sinking = 0.4 V max at 10 mA.
= 1.3 V max at 50 mA.
Probe status 2b (driven at power supply
voltage):
• Load current = 50 mA max.
Output voltages
• Sourcing voltage drop
= 2.6 V max at 10 mA.
= 3.5 V max at 50 mA.
• Sinking voltage drop
= 2.0 V max at 10 mA.
= 2.9 V max at 50 mA.
The 'LOW BATTERY/START', 'PROBE STATUS',
'ERROR' and 'SIGNAL' LEDs will start flashing
red when an output overload has occurred. All
outputs will be switched off. If this occurs, turn off
the power supply and remove the source of the
problem. Turning on the power supply will reset
the RMI-Q.
2.5
RMI-Q basics
!
CAUTIONS:
Power supply voltage
Do not exceed 30 V between the black wire and
the screen wire (green/yellow), or the red wire
and screen wire (green/yellow), or the red and
black wires (power supply), as this could result
in permanent damage to the RMI-Q and/or the
customer power supply.
The use of in-line fuses at the machine cabinet
end is recommended to provide protection for the
RMI and cable.
Screen connection
A good connection must be made to machine
ground (star point).
Output stage circuit
Output stage supplies (+ve, –ve) should not be
switched on and off to enable/disable them as this
can cause the over current protection to switch off
the output completely.
Ensure that outputs from the RMI-Q do not
exceed specified current ratings.

The probe selection inputs P2 and P3 will be level.
Seated start on
When seated start on is selected, the RMI-Q will
not drop the error line until the RMP has become
seated. This provides compatibility with controllers
that regard the RMP to be in error if it is started in
a triggered condition.
0.5 second turn on
0.5 second turn on provides compatibility with
controllers that have quicker response times, to
give a reduced probing cycle time. Standard turn
on time is 1 second. These turn on times apply to
radio M code on only.

RMP - RMI-Q partnership
The RMP and RMI-Q must be placed into
acquisition mode.
On the RMP, acquisition mode achieved using
Trigger Logic™.
On the RMI-Q, acquisition mode is achieved
either by manually power cycling the RMI-Q, or
via application of ReniKey which is a Renishaw
machine macro cycle.
Trigger Logic™ is a method that allows the user
to view and select all available mode settings
in order to customise a probe to suit a specific
application. Trigger Logic™ is activated by battery
insertion and uses a sequence of stylus deflection
(triggering) to systematically lead the user through
the available choices to allow selection of the
required mode options.
Current probe settings can be reviewed by simply
removing the batteries for a minimum of
5 seconds, and then replacing them to activate
the Trigger Logic™ review sequence.
To partner the RMP with the RMI-Q
Partnering is required during initial system set-up.
Further partnering will be required if either the
RMP or RMI-Q are changed.
Any RMP that is partnered with the RMI-Q, but
then used with another system, will need to
be cleared first from the RMI-Q before being
partnered with the new system. The RMP will also
need to be partnered again should it be brought
back to the RMI-Q.
Partnering will not be lost by reconfiguration of
probe settings or when changing batteries.
NOTE: Partnering will be lost when multiple
probe mode is selected. Multiple probe mode
is a function of the RMP. See the relevant RMP
installation guide (see Section 6, 'Parts list').
Partnering can take place anywhere within the
operating envelope.
1. Use Trigger Logic™ to access RMP
configuration mode.
2. Configure switch-on method (if applicable).
3. Configure switch-off method (if applicable).
4. Configure enhanced trigger filter and auto
reset function (if applicable).
5. Enter acquisition mode menu.
6. Power on the RMI-Q or apply one of the
ReniKey commands. Please refer to the
ReniKey programming manual.
7. Watch the RMI-Q P1 system status LED;
after a couple of seconds the LED will
repeatedly flash on and off green. This is
the start of a 60 second interval in which the
RMI-Q is in acquisition mode.
8. Deflect the stylus < 4 seconds to initiate the
acquisition process.
9. After successful acquisition, the RMI-Q P1
system status LED will change to repeatedly
flashing red and yellow (for 5 seconds)
indicating that acquisition is complete and
Probe 1 is full.
10. Leave RMP for 20 seconds to go into
standby.
11. System is ready to use.
NOTES:
To check that turn on and off settings have not
been accidentally changed, insert batteries to
review current probe settings.
When holding the RMP do NOT wrap a hand, or
anything else, around the glass window.
The system will not function correctly if more than
one partnered RMI-Q is within the transmission
range of the RMP.
RMI-Q installation guide
3.4
System
installation
To partner up to four RMPs with the
RMI-Q without ReniKey
The RMI-Q has four machine start inputs
(P1 - P4) that enable partnering of four radio
probes (see wiring diagram on page 3.2).
The partnering procedure is dependant on the
start method that has been selected. See page
2.9 for start methods.
Partnering with dedicated start (Level mode)
If the RMI-Q is powered with all start inputs
held low, the RMI-Q will complete its start up
procedure and partner the RMP as Probe 1.
When the RMI-Q is powered with a single
machine start input held high, the RMI-Q will
complete its start up procedure and partner the
RMP to the probe number represented by the
selected machine start input.
Level mode

P1 P2 P3 P4
Probe 1
Probe 2 Q
Probe 3 Q
Probe 4 Q
The system status LED for the selected probe
number will repeatedly flash on and off green
whilst in acquisition mode.
Partnering with common start
When the RMI-Q is powered, specific machine
start inputs need to be held high when partnering
the RMP to a specific probe number.

NOTES:
Activation of machine start input (P4) is not
required when common start is selected.
To aid partnering, an on/off switch can be fitted
between the machine power supply and the
RMI-Q (red wire). This enables the RMI-Q to
be momentarily powered off and then back on,
for each of the probes being partnered, without
having to power off the machine.
3.5
System
installation
Partnering RMPs using ReniKey
(Recommended)
ReniKey is a Renishaw machine macro cycle. It
enables up to four RMPs to be partnered with
the RMI-Q without the need to power the RMI-Q
off and then back on for each of the probes
being partnered. Please refer to the ReniKey
programming manual for instructions on how
to use ReniKey with your machine's controller.
Alternatively, refer to www.renishaw.com.
Removing the RMP from the RMI-Q
An RMP must be cleared from the RMI-Q when
it is removed from the system. The probe number
is cleared from the RMI-Q by repeating the
partnering procedure whilst the corresponding
machine start input is held high. The RMI-Q
will then display that the probe number was
cleared. Alternatively, the RMP can be cleared via
application of the ReniKey machine macro cycle.
Please refer to the ReniKey programming manual
on how to use ReniKey with your machine's
controller. Alternatively, refer to www.renishaw.
com. ReniKey can also be used to clear all probe
numbers at the same time. If the cleared RMP
is to be used again with the RMI-Q, it must be
re-partnered.
Changing RMP position
If, during partnering with all procedures, the
RMI-Q acquires an RMP that is already stored
under a different probe number, the RMP will be
cleared from its current location and stored under
the new probe number selected for acquisition.

RMI-Q cable
Cable termination
A ferrule should be crimped onto each cable wire
for a more positive connection at the terminal box.
Standard cable variants
The RMI-Q standard cables are 8 m (24.6 ft) and
15 m (49.2 ft) long.
Longer cables are available, please see
Section 6, 'Parts list'.
Cable specification

each core 18 x 0.1 mm.
NOTE:
Maximum cable length:
30 m (98 ft) at 12 V
50 m (164 ft) at 24 V
Cable sealing
Coolant and dirt are prevented from entering the
RMI-Q by the cable sealing gland. The RMI-Q
cable can be protected against physical damage
by fitting flexible conduit if required.
Recommended flexible conduit is Anamet™
Sealtite HFX (5/16 in) polyurethane.
A conduit kit is available - see Section 6, 'Parts
list'.
CAUTIONS:
Failure to adequately protect the cable can result
in system failure due to either cable damage or
coolant ingress through cores into the RMI-Q.
Failure due to inadequate cable protection will
invalidate the warranty.
When tightening or loosening nut B on the
conduit, ensure that torque is only applied
between A and B.
