Using the UNI/32
The UNI/32 provides the communications
link between an ARC156 or Legacy CMnet
network segment and up to 32 U-cards. The
UNI/32 module can store one module driver
and up to 32 Graphic Function Blocks (GFBs),
depending on the size of the GFBs.
A UNI/32 module contains a 32-bit
microprocessor, flash memory, and non-
volatile RAM (stores data even during a
power failure) for executing GFBs. The
UNI/32 can also communicate with an
optional BACview keypad/display using the
Keypad Display port and can communicate
with a laptop computer running WebCTRL or
SuperVision using the UNI/32’s Access port
and an APT.
The module driver varies depending on what
software you are using. WebCTRL requires
the DRV_UNI32 module driver for the UNI/32;
SuperVision requires the UNM module driver.
See the appropriate module driver document
at http://www.automatedlogic.com or on the
SupportPlus CD for more information.
See Figure 1 for a system architecture
diagram.
CAUTION
Changes or modifications to this
unit not expressly approved by the party
responsible for compliance could void the
user’s authority to operate equipment.
NOTE
This equipment has been tested and
found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide
reasonable protection against harmful
interference when the equipment is operated
in a commercial environment. This
equipment generates, uses, and can radiate
radio frequency energy and, if not installed
and used in accordance with the instruction
manual, may cause harmful interference to
radio communications. Operation of this
equipment in a residential area is likely to
cause harmful interference in which case the
user will be required to correct the
interference at his own expense.
