Revised 4/27/00 • UNI/16

© 2000 Automated Logic Corporation
You can power several modules from the
same transformer if you maintain the same
polarity.
The UNI/16 has an operating range of
21.6VAC to 26.4VAC. If voltage measured at
the module’s power input terminals is outside
this range, the module may not work
properly.
1. Turn the module’s power off. This
prevents the module from being powered
up before the proper voltage is verified.
2. Make sure the 24VAC power source is off.
3. Connect the power wires to the module’s
power terminals labeled Ground and
24VAC.
4. Apply power to the transformer.
5. Make sure that 24VAC is present at the
module’s power input terminals.
6. Set the module’s address. Refer to
“Addressing” on page 5 for details about
setting the address.
7. Turn the module’s power switch on.
When the module turns on, the Power,
Run and Error LEDs turn on and the Run
and Error LEDs begin blinking. The Error
LED then turns off. (See “LEDs” on page 7
for more information about LED signals.)
Communicating with the
UNI/16
The UNI/16 connects to the CMnet through
an EIA-485 CMnet port. A five-pin EIA-485
port provides two connections to U-Line
modules on the Unet. You can connect an
optional BACview
1
or BACview
2
keypad
display unit to the keypad display port (see
Figure 2).
NOTE
The EIA-232 port, labeled “Diag Port”
in Figure 2 is reserved for future diagnostic
capabilities. This feature is not yet available.
You must use SuperVision to transfer memory
to the UNI/16. You can connect a portable
computer running SuperVision to the UNI/16
using the module’s Access port. For more
information about connecting to a
workstation, refer to “Communicating with
the Workstation” on page 6.
