European Commission Requirements
This equipment is intended for use in a heavy industrial environment. The equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to other equipment. There is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to other equipment the user is
encouraged to try to correct the interference by one or more of the following measures:
- Re-orientate or relocate the equipment.
- Increase the separation between the pieces of equipment.
- Connect the pieces of equipment on separate mains circuits.
- Ensure that the relevant items of equipment are properly and securely earthed to a common earth point
using adequately sized cable or other means of connection.
Where supplied or specified, shielded interconnection cables must be employed with this equipment to ensure
compliance with the pertinent RF limits. Changes or modifications not expressly approved by the company
could void the user’s authority to operate the equipment.
This product has been rigorously tested to comply with the European EMC (Electromagnetic Compatibility)
Directive. With regard to this, Beta LaserMike recommends that any non-Beta LaserMike peripheral
equipment is CE marked for the Heavy Industrial environment (EN50082-2). Beta LaserMike also
recommends that any cables not supplied by Beta LaserMike, but used for powering Beta LaserMike
equipment, be built using good EMC practices (i.e. cables with braided shield, and connectors with 360
termination of the braid to a metal/metalised shell connector at both ends). If you have any questions
regarding this, contact the Beta LaserMike Service Department.

LaserSpeed 8000/9000 I/O Module Instruction Handbook
Introduction
Part No. 93342 / Drawing No. 0921-01516 Page 7 of 84 Revision E (Dec 2013)
Introduction
The LaserSpeed I/O Module is used to translate the serial output data, Speed,
Length and Gauge Status, from a LaserSpeed 8000 or 9000 Series Gauge to a
parallel output. Optional Profibus and Ethernet field bus are also available in the
I/O Module. The I/O Module connects to the LS9000/LS8000 gauge through a
gauge cable via an RS422 connection, and provides a pass-through connector
for direct access to all the Inputs and Outputs of the LS9000/LS8000 Series
Gauge. A Light Stack connector provides signals to drive a visual indicator (a
light stack) to display the status of the gauge. The I/O Module can also be used
calculate the Elongation Ratio/Differential Speed between two LS8000/LS9000
Series gauges. In addition, the I/O Module can be used to synchronize the
outputs of multiple gauges to output their data at the same time.

Installation
Rear Panel Pin-outs
The following sections describe the various connections to the I/O Module’s rear
panel. Refer to the LS9000/LS8000 Instruction Handbook for further information
about connections to the Gauge.
Power
Accepts IEC 320 power cords. AC power requirements are 90-260VAC,
50/60Hz, 1.5Amps.
I/O Setup
A computer can be connected to this port using a straight-through 9-pin serial
cable for diagnostics and configuration. LaserTrak 4.0 can be used to configure
the LaserSpeed gauge through this port. A NULL modem is not required.
Display
Connects directly to the LaserSpeed I/O Module Display, part number 85871.
This is an LCD indicator that shows the current Length, Velocity, Quality Factor,
and Status.

TO GAUGE
37 pin D connector for connection to the LaserSpeed gauge
cable. This connector is compatible with all cables that have
part number 85277.
PASS-THROUGH
Passes signals from the DB25 connector on a
LS9000/LS8000. The pinout of this connector is compatible
with 25-pin LaserSpeed breakout boxes. Signal descriptions
are listed in a table below.
ETHERNET
Pass-through connector for the LS9000/LS8000 gauge’s
optional Ethernet connection that provides a direct
connection to the gauge over Ethernet. If the attached
gauge does not have the Ethernet option installed, then this
connector is not used.
RS-232
Pass-through connector for the LS9000/LS8000 gauge’s RS-
232 serial port. This connector can be connected to a PC
using a straight-through DB9 serial cable. LaserTrak or a
terminal program can be used to communicate directly with
the gauge via this serial port.

SYNC IN and OUT connector
Used to connect multiple I/O modules together for gauge-gauge synchronization,
and Elongation/Differential Speed calculation. The Sync Out connector of one
I/O module connects to the Sync In connector of the next I/O Module with a
straight-through RJ-45 cable.
IN
Connects to the Master I/O module.
OUT
Connects to SYNC IN of the next I/O Module in the Daisy Chain.
Parallel Outputs
STATUS
Parallel Output for Status / Interlock Control / Shutter Control
VELOCITY
Parallel output for Velocity
LENGTH/ELONGATION
Parallel output for Length or Elongation Ratio
The LENGTH/ELONGATION port can output either Length or the Elongation
Ratio between two gauges, depending on the I/O Module’s position in the
system. All I/O Modules except for the last I/O module in the Daisy Chain
calculate the Elongation Ratio or Differential Speed. The last I/O module in the
Daisy Chain always outputs Length on the Length/Elongation port. All other I/O
Modules output Elongation Ratio if the port is configured for Auto-Elongation
Mode. The ~I:Elongation command is used to configure this mode. By default,
the ~I:Elongation setting should be set to 1 on all I/O Modules. This will cause
the I/O Module to automatically output Elongation if it is being calculated. See
the Elongation/Synchronization section for more information about Elongation.
Note: Elongation Ratio will only be calculated when two gauges are synchronized
together by connecting the Sync Out of one I/O Module to the Sync In of the
other I/O Modules.

Connections
Connect the LaserSpeed 8000/9000 to the TO GAUGE input using the supplied
cable.
Status pins 17, 18, and 26 and 19, 27, and 30 must be connected as shown for
the gauge to operate. An interlock shunt connector is supplied with the interlock
connections pre-wired. Beta LaserMike recommends that you use the supplied
key switch to operate the Laser Interlock. This will provide you with a laser
shutoff for maintenance or material changes.

Parallel Outputs
Data is updated to the bus in one of two modes. The first is called "Data Ready"
mode and the other is called "Data Request" mode. In "Data Ready" mode, the
system will automatically update the data on the Parallel Output Bus each User
Update Period. In "Data Request" mode, the system will update the data on the
Parallel Output Bus only when a Data Requested Signal is received on the Data
Request Input Pin. There are Data Request Input Pins on the Parallel Length/
Elongation port and the Parallel Velocity port. The data output mode is
configured by ~I:AckMode serial command:

~I:AckMode=0
Data Ready Mode
~I:AckMode=1
Data Request Mode
Data Ready Mode
In Data Ready mode, the I/O module outputs data each time a new measurement
is received from the LaserSpeed gauge. An optically isolated signal called "Data
Ready," located on the Length/Elongation and the Velocity Output connectors,
are provided to indicate when data has been upated and is valid. The Data
Ready pulse indicates that the data bus has been updated with new data and that
the signals on the bus are completely settled. Both Data Ready True (Rising
Edge Trigger, signal driven from ground to Voltage high) and Data Ready False
(Falling Edge Trigger, signal driven from Voltage high to ground) are provided.
When using Data Ready True, data should be read from the bus on the rising
edge of the signal, and when using Data Ready False, data should be read on
the falling edge. Either the leading edge or the active level of the signal can be
used to trigger a read by your interface.
Ringing on the line can occur if the cable is not properly terminated. This can
cause the data to be unstable during the time of the active edge of the data ready
signal. Allow for extra settling time if ringing occurs.

Data Ready (True)
Active High

Data Ready (False)
Active Low
Falling Edge
Data is valid from the time that the Data Ready signal is asserted until the time
that the next data point is received from the gauge. This time varies depending
on the gauge’s Update Rate configuration setting. See the timing specifications
below for detailed timing information.
