Turbo PMAC PCI Lite
6 Hardware Setup
Board Reset/Save Jumpers
E50: Flash-Save Enable/Disable Control – If E50 is ON (default), the active software configuration of
the PMAC can be stored to non-volatile flash memory with the
SAVE
command. If the jumper on E50 is
removed, this Save function is disabled, and the contents of the flash memory cannot be changed.
E51: Re-Initialization on Reset Control – If E51 is OFF (default), PMAC executes a normal reset,
loading active memory from the last saved configuration in non-volatile flash memory. If E51 is ON,
PMAC re-initializes on reset, loading active memory with the factory default values.
Communication Jumpers
PCI Bus Base Address Control
–
The selection of the base address of the card in the I/O space of the
host PC's expansion bus is assigned automatically by the operating system and it is not selected through a
jumper configuration.
E49: Serial Communications Parity Control
– Jump pin 1 to 2 for NO serial parity. Remove jumper for
ODD serial parity.
E55-E65: Interrupt Source Control – These jumpers control which signals are tied to interrupt lines
IR5, IR6 and IR7 on PMAC’s programmable interrupt controller (PIC), as shown in the interrupt
diagram. Only one signal may be tied into each of these lines.
E110: Serial Port Configure – Jump pin 1 to 2 for use of the J4 connector as RS-232. Jump pin 2 to 3
for use of the J4 connector as RS-422.
E111: Clock Lines Output Enable
– Jump pin 1 to 2 to enable the Phase, Servo and Init lines on the J4
connector. Jump pin 2 to 3 to disable the Phase, Servo and Init lines on the J4 connector. E111 on
positions 1 to 2 is necessary for daisy-chained PMACs sharing the clock lines for synchronization.
I/O Configuration Jumpers
Caution:
A wrong setting of these jumpers will damage the associated output IC.
E1-E2: Machine Output Supply Configure – With the default sinking output driver IC (ULN2803A or
equivalent) in U13 for the J5 JOPTO port outputs, these jumpers must connect pins 1 and 2 to supply the
IC correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these
jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.
E7: Machine Input Source/Sink Control – With this jumper connecting pins 1 and 2 (default) the
machine input lines on the J5 JOPTO port are pulled up to +5V or the externally provided supply voltage
for the port. This configuration is suitable for sinking drivers. If the jumper is changes to connect pins 2
and 3, these lines are pulled down to GND. This configuration is suitable for sourcing drivers.
E17A - E17D: Motors 1-4 Amplifier-Enable Polarity Control – Jumpers E17A through E17D control
the polarity of the amplifier enable signal for the corresponding motor 1 to 4. When the jumper is ON
(default), the amplifier-enable line for the corresponding motor is low true so the enable state is low-
voltage output and sinking current, and the disable state is not conducting current. With the default
ULN2803A sinking driver used by the PMAC on U37, this is the fail-safe option, allowing the circuit to
fail in the disable state. With this jumper OFF, the amplifier-enable line is high true so the enable state is
not conducting current, and the disable state is low-voltage output and sinking current. Generally, this
setting is not recommended.
E28: Following-Error/Watchdog-Timer Signal Control – With this jumper connecting pins 2 and 3
(default), the FEFCO/ output on pin 57 of the J8 JMACH1 servo connector outputs the watchdog timer
