1 SECTION
INTRODUCTION
1.1 FEATURES
The VMIVME-2131 is capable of delivering 64 channels of high current
output. These outputs can be current sourcing or current sinking. The VMIVME-
2131 is designed with a breakdown voltage of 35 V minimum. A unique feature of
the VMIVME-2131 Board is the Built-in-Test (BIT) logic, which allows the user, under
software control, to verify the operation of each channel.
A brief overview of the VMIVME-2131's features includes:
a. 64 bits of high current outputs.
b. Outputs may be current sourcing/High-Z or current source/sinks.
c. Output transient protected.
d. High-breakdown voltage (35 V minimum).
e. Tri-state outputs.
f. Built-in-Test logic for fault isolation.
g. High reliability DIN type output connectors.
h. 8-, 16-, or 32-bit transfers.
i. Double Eurocard form factor.
j. ±3.5 A peak output current (100 msec, 10 percent duty cycle).
k. 500 mA continuous current (fan cooled).
l. Thermal shutdown protection.
m. Front panel software controlled Failed LED for Built-in-Test.
n. Separate user configurable address jumpers for the Control and Status
Register (CSR) and the Data Registers allow for contiguous data
addressing when more than one I/O board is used in a VMEbus system.
1.2 FUNCTIONAL DESCRIPTION
The VMIVME-2131 is a member of VMIC's MEGAMODULE™ family. It is
designed with common programming features such that subsystems may be
configured with contiguous I/O addresses to conserve memory. Each of these
boards (VMIVME-1110, VMIVME-2130, VMIVME-2131, VMIVME-2120, and
VMIVME-2510) is designed with two sets of board address switches or jumpers to
provide an efficient memory address map for CSR and I/O addresses. CSR
