UMAC Turbo CPU/Communications Board Hardware Manual

INTRODUCTION

The UMAC (Universal Motion and Automation Controller) is a modular system built with a set of 3U­format Eurocards. The configuration of any UMAC system starts with the selection of the UMAC Turbo
CPU/Communications Board and continues with the addition of the necessary axes boards, I/O boards,
and any other interface boards selected from a variety of available accessories.

The UMAC Turbo CPU/Communications Board (part number 3x0-603766-10x) is a member of the
Turbo PMAC2 family of boards. It is software is capable of 32 axes of control. Accessory boards
installed in the UMAC Turbo system interface between the UMAC Turbo CPU/Communications Board
and the machine to output amplifier command signals, to input feedback information, and to input flags
information including end-of-travel limits and machine home sensors. Different kind of axes interface
boards can be selected to control analog ±10V amplifiers, stepper drivers and direct digital PWM
amplifiers.

Several methods of communications can be implemented between the UMAC Turbo System and the host
computer. These methods include two RS-232 serial ports, USB, Ethernet and PC/104 bus
communications. The UMAC Turbo CPU/Communications Board can communicate at the same time
with the two RS-232 ports, USB or Ethernet ports. However, if PC/104 bus communications is used, the
USB or Ethernet ports cannot be used.

Upgrade Issues

The UMAC Turbo CPU/Communications Board can be used to replace both the older UMAC CPU board
(part number 3x0-603382-10x) and the Acc-54E USB/Ethernet communications board (part number 3x0­603467-10x). Combining both of these functions onto a single board saves both money and rack space.
The UMAC Turbo CPU/Communications Board supports high-speed CPUs (160 MHz and 240 MHz)
than the older UMAC CPU board, but it also supports the 80 MHz and 100 MHz configurations of the old
board.

Usually, use of the UMAC Turbo CPU/Communications Board is compatible with older UMAC CPU
board and Acc-54E communications board. However, the base address of the DPRAM IC on the
CPU/Communications Board is $060000, whereas the base address of the DPRAM on the Acc-54E is
higher ($06C000 by default).

Setup variable I24 should be set to $060000 (or $0) to use the automatic functions in the on-board DPRAM
IC. Any M-variable used for DPRAM registers should be in the $060000 - $0603FFF address range.

The following list summarizes the differences with respect to the older version:

 Addition of on-board USB and Ethernet
 Support for 160 MHz and 240 MHz CPUs (Opt 5Ex and 5Fx)
 Main serial connector reduced to 10-pins and RS-232 only
 Elimination of upward stack connectors for axis boards
 Addition of watchdog timer relay
 Elimination of voltage interlock circuit

Jumpers Setup Summary 6

UMAC Turbo CPU/Communications Board Hardware Manual

JUMPER SETUP SUMMARY

On the UMAC Turbo CPU/Communications Board, there are many jumpers (pairs of metal prongs),
called E-points. Some have been shorted together; others have been left open. These jumpers customize
the hardware features of the board for a given application and must be set up appropriately. The
following is an overview of the several UMAC Turbo CPU/Communications Board jumpers.

Clock Source Jumpers

In order to operate, the board must receive servo and phase clock signals from a source external to the
board. These clock signals can be brought into the board from one of two possible ports: the UBUS
backplane connector, or the front-side main serial-port connector. Jumpers E1A and E1B must be
configured properly for the clock source used.

To receive the clock signals over the UBUS backplane, usually from an Acc-24E2x axis-interface board
or an Acc-5E MACRO-interface board, E1A must connect pins 1 and 2, and E1B must connect pins 2 and

3. Use this default setup in most cases.
To receive the clock signals through the main serial port, usually from another PMAC system or a

reference signal generator, E1A must connect pins 2 and 3 and E1B must connect pins 1 and 2. Though
rarely used, this configuration permits complete synchronization to the system that is generating the clock
signals.

To either input or output the clock signals through the J7 serial port, jumpers E17A, E17B, E18A, and
E18B must be configured in positions 2-3. Otherwise, these jumpers must be set at position 1-2.

Watchdog Timer Jumper

Jumper E19 should be OFF for normal operation, leaving the watchdog timer circuit active and prepared
to shut down the card in case of a severe problem. Putting jumper E19 ON disables the watchdog timer
circuit. This should be used for test purposes only to try to track down the source of watchdog timer trips.
Normal operation of a system with this jumper ON should never be attempted, as an important safety
feature is disabled.

Operation Mode Jumpers

Jumpers E20, E21, and E22 control the operational mode of the UMAC Turbo CPU/Communications
Board. For normal operation, E20 must be OFF, E21 must be ON, and E22 must be ON. Other settings
of these jumpers are for factory use only.

Firmware Reload Jumper

Jumper E23 should be OFF for normal operation. To load new firmware into the flash-memory IC on the
CPU, E23 should be ON when the card is powered up. This puts the card in bootstrap mode, and ready to
accept a new firmware. Then try to establish communications to the card with the Executive program, the
Executive program will recognize that the card is in bootstrap mode automatically, and prompt for the
firmware file to download.

Re-Initialization Jumper

If jumper E3 is installed when the board is powered-up or reset, the board firmware will go through a re­initialization process, returning most I-variables to factory default values. The last saved values are not
lost when this happens. It will also go through a system auto-detection process, selecting which of the
Servo ICs that it finds will be the source of the servo and phase clock signals for the system. Typically,
this jumper is used only when the system’s setup has a problem severe enough that communications does
not work – otherwise, a $$$*** command can be used for re-initialization.

Jumpers Setup Summary 7

UMAC Turbo CPU/Communications Board Hardware Manual

Reference Voltage Connect Jumper

Jumper E12 permits the reference voltage for the analog and digital circuits in the UMAC Turbo
CPU/Communications Board to be tied together. If not isolating the analog circuits from the digital
circuits, this jumper should be ON. If isolating the analog circuits from the digital circuits using separate
isolated supplies for the two circuits, this jumper should be OFF.

Interrupt Select Jumpers

If the PC/104-bus interface is installed, the UMAC Turbo CPU/Communications Board can interrupt the
PC/104 host computer over one of four interrupt lines as selected by jumpers E7 – E10. One of these
jumpers should be ON in any configuration.

 E7 ON selects interrupt line IRQ10
 E8 ON selects interrupt line IRQ11
 E9 ON selects interrupt line IRQ12
 E10 ON selects interrupt line IRQ15

Flash Memory Bank Select Jumpers

The flash-memory IC has the capacity for eight separate banks of firmware, only one of which can be
used at any given time. The eight combinations of settings for jumpers E25A, E25B, and E25C select
which bank of the flash memory is used. In the factory production process, firmware is loaded only into
Bank 0, which is selected by having all of these jumpers OFF.

PC/104 Bus Use Selection

If the PC/104 bus communications method is used, jumper E5 must be installed in position 1-2. If the
USB or Ethernet communications ports are used, jumper E5 must be installed in position 2-3.

USB/Ethernet Firmware Reload Jumpers

Jumper E1 should be OFF to engage the “Write Protect” feature. This is the default factory shipped
setting. To load new firmware into the USB/Ethernet micro-controller jumper E1 must be installed to
disable “Write Protect”.

Jumper E6 should be ON for normal operation. Jumper E6 should only be removed when directed by a
Delta Tau Technical Support Engineer to reset the USB/Ethernet processor. To do so jumper E6 should
be removed (OFF) before the card is powered; this puts the on-board USB/Ethernet micro-controller in
bootstrap mode. After power-on the jumper must be replaced (ON) to allow writing to the micro­controller to accept new firmware (as well as setting ON the E1 jumper).

Note:

The jumper E1 may be left in the ON position but this will disable the “Write
Protect” feature.

Jumpers Setup Summary 8

UMAC Turbo CPU/Communications Board Hardware Manual

CONNECTIONS

Backplane (UMAC) Connections

To connect the UMAC Turbo CPU/Communications Board to the UBUS backplane, simply insert the P1
connector into one of the sockets on an Acc-Ux UBUS backplane board. It does not matter which socket
on the UBUS backplane board is used, although customarily, the CPU board is installed in the leftmost
slot. Typically, the backplane board will have been installed already in a Eurorack frame (Acc-Px or
equivalent), so the CPU board is simply slid into one of the slot guides in the frame until it mates with the
backplane board; then the front-plate screws are tightened for a firm connection to the rack and
backplane.

If a power supply has been connected to the UBUS backplane board, this power will be supplied
automatically to the Turbo CPU board. The UBUS backplane board is capable of supplying isolated
analog and digital supplies, but the 3U-format power supplies (Acc-Ex) provided by Delta Tau do not
keep these two supplies isolated from each other.

PC/104 Connections

If the PC/104 connector is installed, the UMAC Turbo CPU/Communications Board may be mounted on
the top of a PC/104 stack. Because it does not pass the connector through, it may be mounted only on the
top of such a stack. The UMAC Turbo CPU/Communications Board has four mounting holes in the
standard PC/104 locations for standoff connections to the PC/104 stack. Note that the PC/104 connector
used on the UMAC Turbo CPU/Communications Board provides for the Eurocard 4T standard of 20 mm

(0.8”) spacing between boards, not the PC/104 standard of 15mm (0.6”), so standoff lengths must be

chosen accordingly.

Serial Port Connections

The standard J7 serial-port connector on the front edge of the UMAC Turbo CPU/Communications Board
is an IDC 10-pin header. The connector is designed so that a standard flat-cable connection (such as a
Delta Tau Acc-3L cable) to a DB-9 connector can be used. From there, a standard DB25-to-DB9 adapter
can be used if necessary. The servo and phase clock signals can be either input or output on this
connector, depending on the setting of jumpers E1A, E1B, E17A, E17B, E18A and E18B.

The auxiliary J8 serial-port connector is also an IDC 10-pin header. The connector is designed so that a
standard flat-cable connection (such as a Delta Tau Acc-3L cable) to a DB-9 connector can be used.
From there, a standard DB9-to-DB25 adapter can be used, if necessary.
