FUNCTIONAL CHARACTERISTICS
Compliance: This product complies with the
VMEbus specification Rev. C. 1 with the following
mnemonics:
A16:D32, D16, D08 (EO): 29, 2D: Slave
6U form factor
Address Modifier Codes: Jumper-selectable for
short supervisory or short nonprivileged I/O access.
Factory configured for short supervisory I/O access.
Addressing Scheme: Four ports individually
addressable on 8-, 16-, or 32-bit boundaries. The
separate board address decoder for the Control and
Status Register (CSR) and Board ID Register allows
addresses for hardware control to be grouped for
improved software efficiency.
Data Transfer: Supports 8-, 16-, or 32-bit data
transfers
OUTPUT SPECIFICATION SUMMARY
Output Organization: Four ports, eight bits wide.
Addressable to any address within short supervisory or
short nonprivileged I/O map.
Output Features: The high-current driver (600 mA
sink) outputs are designed to drive incandescent lamps
and inductive loads without external current limiting or
warming resistors. Due to cold filament inrush currents,
it is recommended that only one lamp be driven by the
output driver. However, if more than one bulb must be
driven by a single wire, then another driver may be
connected in parallel. If more than one bulb must be
driven by a single output, it is recommended the
VMIVME-2131 (current source/sink) or the
VMIVME-2130 (current source only) be used.The output drivers also feature: thermal current
shutdown protection, high breakdown voltage (60 V),
and output clamp diodes for inductive flyback
protection. Details concerning the output driver design
and description are shown on page 3.
Pull-up resistors for TTL or electronic switch outputs are
optional.
Output Sustaining Voltage: 35 V minimum
Overcurrent Protected Output Voltage: 25 V
Output Saturation Voltage: See Tables 3 and 4
Output Data Option: Positive true or negative true
options
INPUT SPECIFICATION SUMMARY
Single-Ended Signal Input Characteristics: High
input impedance (33 k?). Threshold accuracy of 1
percent over entire 60 V range (typical). Refer to
Figure 4 for typical single-ended signal conditioning
electronics.
Differential Signal Input Characteristics:
Common-mode input voltage range: -30 to + 60 V Input
sensitivity of ±100 mV over common-mode range of -7
to +12 V
High input impedance (33 k?)
