System Components
The Tektronix DCS1000 Data Collection System is a family of instruments and
software designed to work together.
Component Descriptions
Components of the DCS1000 are described below.
H The VX4244 Digitizer Module provides 16 channels of 16-bit differential
input, analog-to-digital conversion data, and sampling up to 800 kHz. If the
VX4780 is not part of the configuration, the VX4244 uses the VX1746
(input) and the optional VX1658P (I/O) cables.
H The VX4780 Signal Conditioner is a 16-channel signal conditioning module
that accepts the signals of sixteen transducers, amplifies and filters the
signals. It then outputs the results to the VX4244 Digitizer Module. It uses
the VX1744, VX1745 and the optional VX1658P (I/O) cables.
H The VX4570 Mass Storage Controller Module provides an interface between
the VXIbus and the mass storage device (SCSI hard drive). The VX4570
will be a VXI Commander; it moves data from its data collector Servants
(one or two VX4244 Modules) to shared memory in the VX4570 and then
on to the mass storage device. The VX4570 is also the commander of the
VX4780 modules associated with the VX4244s under its control.
DCS1000 Data Collection System
H The System Management Control Software (SMCS), which runs in a
Windows environment, resides on the host controller of the system.
VXIplug&play drivers are included in the SMCS. The plug&play drivers are
optimized for operation as part of an overall system, and differ from the
individual module drivers. With the SMCS, the user controls the VX4570 as
a tool for test scenarios, causing it to program its servants, start an acquisition process, and record data from its servants to disk media.
H The DCS1000 uses a 4 Gbyte (VX4GBD) hard drive with a SCSI-2 cable.
H The mainframe for the DCS1000 can be either the VX1406 6-slot or any
VXI mainframe with adequate power and cooling capacity (such as the
Tektronix VX1410 or VX1411).
H The MXI2PCI (PCIbus) Slot 0 module uses one slot in the card cage. It
allows you to daisy chain multiple card cages.
Refer to the individual component user manuals for more information on
individual DCS1000 components.

System Components
System Configuration
Component selection and configuration of the DCS1000 depends on your
application. There are a number of ways to correctly set up the system. Refer to
the following information for set up instructions.
H If your system includes a VX4570 System Controller, it must be installed to
the left of any other DCS1000 modules with the exception of the Slot 0
controller.
H The physical location of the VX4570 should be to the left of all servant
modules. The logical address of the VX4570 should numerically precede the
servants logical addresses. Also, all of the servants must have logical
addresses that are incrementally sequential to the VX4570. The logical
addresses should increment starting with the module directly to the right of
the VX4570 and continue to the right for each servant in the system. For
example, if the VX4570 has logical address 02, then the next DCS1000
module must be in the adjacent slot to its right, and must have a logical
address of 03, and so on.
Module Switch Settings
H If you have installed a VX4780 Signal Conditioner, the system will pair it
with the VX4244 Digitizer with the lowest logical address. Be sure the
cabling is correct for this pairing. For example, if your card cage has two
VX4244s in slots 2 and 3 with logical addresses 02 and 03, and a VX4780 in
slot 4 with logical address 04, the system will assume that the VX4244 in
slot 2 is cabled together with the VX4780.
H VX4244 Modules without corresponding VX4780 Modules require the
VX1746 (input) cable. The VX1658P (I/O) cable is optional and can be
ordered seperately. The VX1746 cable is required if two VX4244s and one
VX4780 is installed.
H The environmental requirements for the disk drive are lower than what is
specified for all other components of the DCS1000. This means that a
DCS1000 that includes a drive assembly should be restricted to the drive
environmental specifications, shown in the Specification section of this
manual.
Following the procedures below, configure the DCS1000 modules and install
them in the mainframe. The location of the switches are shown in the diagrams
associated with each module.
A detailed description of these switches is given in each module user manual.
For All Modules. Set the Logical Address switches for each module. Each
function module in a VXIbus System must be assigned a unique logical address,
from 1 to 255 decimal. The base VMEbus address of the modules are set to
2
DCS1000 Data Collection System
System Components
values between 1 and FFh (255d) by two hexadecimal rotary switches. Align the
desired switch position with the arrow on the module shield.
To avoid confusion, it is recommended that the slot number and the logical
address be the same. The Logical Address of the VX4570 System Controller
should numerically precede the DCS1000 servant modules logical addresses. The
servant modules must have logical addresses that are incrementally sequential to
the VX4570. The logical addresses should increment starting with the module
directly to the right of the VX4570 and continue to the right for each servant
module.
In order to use and program the DCS1000 modules in an IEEE-488 environment
you must know the IEEE-488 address of the module. Different manufacturers of
IEEE-488 interface devices might have different algorithms for equating a
logical address with an IEEE-488 address. Consult the operating manual of the
IEEE-488 Interface module being used.
VX4244 Switches. The VX4244 has Logical Address switches.

VX4780 Switches. In addition to the Logical Address switches, the VX4780 also
has a Halt switch and an Interrupt Level switch that must be correctly set.
H Halt Switch.
Switch S1481 contains four rockers. Rocker number 1 serves as a Halt
Switch. The setting of this switch selects the response of the VX4780
Module when the Reset bit in the module VXIbus Control register is set. If
the Halt switch is in the closed position, the VX4780 is reset to its power-on
state and all programmed module parameters are set to their default values. If
the Halt switch is set to the open position, the module will ignore the Reset
bit and no action will take place.

H VME Interrupt Level Select Switch.
Each function module in a VXIbus system can generate an interrupt at a
specified level on the VMEbus to request service from the interrupt handler
located on its commander. Set the interrupt level to the same level as the
interrupt handler on that commander. The VMEbus interrupt level on which
the VX4780 Signal Conditioner generates interrupts is set by a rotary switch,
S88 INTRPT. Align the desired switch position with the arrow on the
module shield.
Valid VMEbus Interrupt Level Select switch settings are 1 through 7, with
setting one equivalent to level one, and so on. The level chosen should be the
same as the level set on the VX4780 interrupt handler, typically the module
commander. Setting the switch to 0 or 8 will disable the module interrupts.
Do not use switch settings 9 through F.
Interrupts are used by the module to return VXIbus Protocol Events to the
module commander. Refer to the Operating Basics section of the VX4780
User manual for more information on interrupts. The VXIbus Protocol
Events supported by the module are listed in Appendix A: Specifications of
the user manual.
VX4570 Switches. In addition to the Logical Address switches, the VX4570 also
has Configuration switches which must be set. There are two 8-position rocker

switches labeled S1061 and S1071 in the lower rear portion of the board. Refer
to Figure 3 for switch locations. The settings for the switches are as listed.
H S1061 rockers 1 and 2 – VMEbus Arbitration Level
These two rockers determine which bus Request level will be used by the
VX4570 when it requires use of the VMEbus. The setting, of rockers 1 and 2
for the required Bus Request levels, is shown in Table 1.

H S1061 rockers 4 through 8 – Unused
H S1071 rockers 1 through 4 – Servant Area Size
These 4 switches select how many data collector servants will be granted to
the VX4570 when the VXI Resource Manager configures the system

DCS1000 Data Collection System
Installation
This section describes how to install the VXIbus modules, explains cable
requirements, and provides installation checklists to record necessary information.
Tools Required
A slotted screwdriver set is required for proper installation.
Requirements and Cautions
The DCS1000 modules are C-size VXIbus instrument modules and therefore
may be installed in any C- or D-size VXIbus mainframe slot other than Slot 0.
To install the module in a D-size mainframe, consult the Operating manual for
the mainframe. Refer to Configuration for information on selecting and setting
the Logical Address switch of the module. This switch defines the programming
address of your module. To avoid confusion, it is recommended that the slot
number and the logical address be the same.
NOTE. There are two printed ejector handles on each card. To avoid installing
a card incorrectly, make sure the ejector marked with the model number is at
the top.
CAUTION. Overheating can damage electronic components. Verify that the
mainframe is able to provide adequate cooling and power with all the modules

Hard Drive Installation
Installation
If problems still persist, contact your Tektronix field office or representative for
service assistance. For technical assistance with application questions, please
contact the Measurement Business Division Customer Support Center at
800-835-9433 (800 TEK-WIDE), extension 2400.
Refer to the individual User Manual for each instrument for details on their
commands and operation.
Follow these step to install the hard drive:
1. Power off the DCS1000 system and all peripherals before working on the
SCSI-bus devices.
2. Set the SCSI ID switch, which is located under the drive enclosure.
Determine the SCSI ID you want to use for the SCSI hard drive used in the
DCS1000 system. Valid choices are 0 through 6. When the hard drive is first
initialized, the address must be set to 6. The DCS1000 hard drives(4 Gbyte)
has a switch, located on the underside of the drive enclosure, to set the SCSI
ID. The switch includes a display for the current SCSI ID. Power must be off
when changing the SCSI ID. If more than one SCSI drive is used, notice that
no two devices can use the same SCSI ID on the same SCSI-bus.
For information on installing more than one SCSI device refer to the
Installation manual included with the DCS1000 SCSI hard drive.
3. Connect the SCSI-bus cable to the VX4570 and the hard drive. Install the
terminator.
On the VX4570 single ended SCSI-bus, you must have a terminator placed
at each physical end of the bus. The external terminator should be attached
into the remaining plug, after the SCSI-2 cable is connected, on the back of
the SCSI hard drive cabinet. The SCSI-2 cable provided with the DCS1000
hard drive is 1 meter in length. The total length of the SCSI-bus should
never exceed 6 meters.
NOTE. Enclosure fan clearance for the VX4GBD requires 2 inches minimum
space on all sides.
4. Apply power to the hard drive. Wait at least 20 seconds for the hard drive to
begin operation.
5. Apply power to the DCS1000 system and any peripherals. Pay attention to
the power on process to see that there are no errors.

8. Choose OK to return to the first SMCS screen.
VX4570 Method. Execute the two VX4570 commands shown in Table 4 to
recognize and initialize the SCSI hard drive. The INITialize command must be
executed first.
T able 4: Initialization commands
Commands Description
MMEMory:INITialize The “INITialize” command initializes (formats)
the specified mass storage media. If the
<msus> parameter is not specified, the default
is used. The default is the <msus> selected at
*RST, not the currently selected <msus>.
Any previous data on the media is destroyed
when the media is initialized.
MMEMory:MSIS[<msus>] The “Mass Storage IS”command selects a
default mass storage device which is used by
all MMEMory commands except INITialize. If
the parameter is omitted, the devide dependent setting for default mass storage device is
selected.

Troubleshooting
If the DCS1000 system is unable to recognize the SCSI hard drive or you have
errors reading from or writing to it, you may have a SCSI-bus problem.
SCSI bus errors. The following are common SCSI bus errors:
H The hard drive was not initialized prior to start-up. Set the SCSI hard drive
to an address of 6. Refer to Initializing on page 16 of this manual for more
information.
H Total physical length of the bus cable exceeds 6 meters. Use a shorter
connecting cable.
H Conflicting SCSI ID on two devices. Choose a SCSI hard drive ID
numbered 0 through 6. The VX4570 uses an address of number 7.
H Power on was initiated incorrectly. Apply power again using the correct
sequence described on page 15 of this manual.
CAUTION. To avoid damage to the SCSI devices and the DCS1000 system, do not
make SCSI bus connections when system components are powered on.
H Cable connection is incorrect or cable needs to be replaced. Replace cables
or remove some devices from the SCSI bus before initializing.
