Important Details
Secure all the cables to prevent the connectors from dropping into hazardous positions (for
example the oor or coolant tray) when they are unplugged.
Route all cables to prevent them from being caught on moving parts.
The NMS800 is grounded to the machine, using the braided grounding lead provided, before
the machine supply is turned on.
The power has been disconnected, before the encoder(s) are connected.
The NMS800 is compatible with Newall Spherosyn Serial and Microsyn Serial encoders, along with other
encoders.
It is important to ensure that:
Do not connect this unit directly to the mains supply.

conditions.
Settings available for brightness:
mid
The default brightness is medium
Press the axis select key next to the axis to cycle through the options

Setting to low brightness decreases the display brightness to its minimum

15
Setting up the unit `
This setting enables the user to dene an automatic sleep mode after a period of time. The user either leaves the
default setting at ‘0’ which deactivates the sleep mode, or selects a numeric value when the sleep mode is initiat-
ed after no operation of the NMS 800
To exit sleep mode, simply move an axis or press any key.
0
The default setting is set to 0 minutes
To set the time, simply insert the number of minutes (using the numerical keypad) into the DRO and press
5
Sleep function active after 5 minutes `
Once input, simple press the undo key, which will take you out of this menu.
Sleep Timer Setup
Axis Legend setup

axis legend
editing
The axis legend setting allows you redene all the axes on the DRO, using the key to select
which axis you would like to redene.
The numeric keypad then allows you to add which letter you would like to label the axis with.
Once you’ve selected the axis, your screen will change to show
editing.
Simply insert the letter you would like to be shown on this axis.
To apply, press the key.

16
Setting up the unit
DRO Type setup
This seting enables the user to choose the machine type that the NMS800 operates with. This is important
as the machine type denes the default functions for the function keys and function menu.
There are two di󰀨erent settings for this DRO:
lathe millv
= Feed Function
= Summing Function
= Blank Function
= PCD Function
= Sub-Datum Function
= Blank Function
Note: The function key can be manually set to any function desired, see the function keys
Scale Factor setup
The Scale factor setting on the NMS 800 allows you to scale the DRO to the travel on your lathe or milling
machine. This can be set by entering you preferred scale using the numeric keypad.
When on the setting simply insert the scale factor required and hit the key.
1.000
This shows that the scale factor is set to 1:1 and will show the exact unit.
2.000
This shows that the scale factor is set to 2:1 and will show double what the travel is.
5.000
This shows that the scale factor is set to 5:1 and will show 5 times the travel.
Once input, simple press the undo key, which will take you out of this menu.

17
Setting up the unit
Beep Enable setup
This DRO setting allows you to enable and disable any noise from the DRO. This function can be enabled
or disabled through the DRO setup menu.
on
off
This shows that the DRO will make a sound when keys are pressed.
This shows that the DRO will not make a sound when keys are pressed.
To cycle through these options, press the key next to the ‘x’ axis and then to exit.
Feed rate setup
The feed rate setting can be changed between minutes and seconds. These can be in both ‘mm’ and ‘inch’,
these give the options of:
In/minutes, in/seconds, mm/minutes and mm/seconds. To set this press the key.
minutes
seconds
This shows that the DRO is set to minutes.
This shows that the DRO is set to seconds.
To cycle through these options, press the key next to the ‘x’ axis and then to exit.
Function setup
The function setup allows you to scroll through all the di󰀨erent function on the NMS 800 and activate them
within the DRO.
To scroll through the di󰀨erent setting press the key.

off
This shows that the function is on.
This shows that the function is o󰀨.
To cycle through these options, press the key next to the ‘x’ axis and then to exit.
Note: The function key can be manually set to any function desired, see the function keys

18
Setting up the unit
Digital type setup
The digital type setting is a very important setting to tell the NMS 800 which type of encoder your using with
your machinery.
There are 4 options to use with the NMS 800: (These apply if more than one axes are digital)
rot dec
rot dms
linear
rot rpm
This shows that the DRO is for: Rotary decimal.
This shows that the DRO is for: Rotary degrees, minutes and seconds.
This shows that the DRO is for: Rotary revolutions per minute.
This shows that the DRO is for: Linear encoders.
To cycle through these options, press the key next to the ‘w’ axis and then to exit.
The Rotary mode setup allows you to change the NMS 800 between two settings. These are for when a
rotary encoder is being used with this DRO.
The two settings are: (These apply if more then one axes are digital)
contin
rollover
Continuous: This feature does not stop at 360° and will carry on past.
Roll over: This feature will stop at 360° and start back at 0°.
To cycle through these options, press the key next to the ‘w’ axis and then to exit.
Rotary Mode setup
The digital resolution feature is used for rotary encoders, this can be set to the resolution of the rotary en-
coder.
There is two ways to set this resolution, using key to access these. The two are:
program
teach
Program allows you to input your resolution using the keypad.
Teach, using a a reference mark on the encoder, will set the resolution on the NMS800.
Digital Res setup

19
Setting up the unit
Gear ratio setup.
Once set, press the key to return.
The Gear ratio setup allows you to scale your rotary encoder to any equipment in-between your encoder and
your end product. The NMS 800 is set to a 1:1 ratio at factor settings.
You can change this ratio setting by pressing the key, and entering a value using the numeric key-
pad.
Signal Check setup
The signal check feature allow you to enable or disable the comparison of the encoder signal to the table
shown below. If this setting is enabled, and the signal does not match the table below, it will return with a
SIG-FAIL message. (If 1 or more axes are digital)
To cycle between these press the key along the ‘w’ axis.
off
on
This shows the signal check is enabled and will show an error.
This shows the signal check is disabled and will accept any signal.
A B RM STATUS
L L H SIG FAIL
L H X OK
H L X OK
X X L OK
When this setting is enabled, the NMS 800 will check for the di󰀨erent signals required. If the signal retrieved
is an illegal signal, the DRO will return with SIG FAIL as shown in the table below. If a signal comes back
and is correct, the DRO will continue as normal.
Once set, press the key to return.
X=Don’t care state, L= Low state and H= High state.

Setting up the unit
Quad Index setup
Display Resolution setup
The display resolution settings available for each axis can not be ner than the encoder resolution. The inch/
mm setting will also dene the resolution that is actually displayed as per the below table:
Display
µmm in
0.1 0.0001 0.000004
0.5 0.0005 0.00002
1 0.001 0.00005
2 0.002 0.0001
5 0.005 0.0002
10 0.01 0.0005
Press the axis select key next to the axis to cycle through the options
The quad index setting on he NMS800 activates the reference mark (Z). When this setting is o󰀨 the DRO will
only check for the A and B quadratures signals, but when this setting is activated, the DRO will check for A
and B along with the Z quadrature signals.
The Two settings are:
off
on
This will be checking for A, B and Z
This will only check for A and B
