Controls and Indicators The HNET/UFP side panel of the VPM contains one reset switch, three LEDs, one
termination switch and one HNET address switch as shown in Figure 2.
A reset switch is located on the top of the panel. Pushing the reset switch
re-initializes the VPM operation.
POWER (Green) Normally ON. When illuminated, indi-
cates that power for the VPM is applied
to the module.
CPU FAIL (Yellow) Normally OFF. When illuminated, indi-
cates that the module microprocessor
has failed.
HNET/UFP FAIL (Yellow) Normally OFF. When illuminated, indi-
cates that the HNET/UFP communication
with the VPM has terminated.
A three-position switch located directly beneath the LEDs on the HNET side of the
VPM is used to set the HNET network address of the VPM.
PRE-INSTALLATION Before connecting either the HLI, power or the HNET, the network address must be set
for the VPM using the
three-position switch.
(Refer to Figure 2 for the
location of the switch.)
The address for the VPM
must be the same as the
address selected for it in
the Zeus Programming
Tool. To increment each
digit of the address,
press the “+” button
above the desired digit;
to decrement each digit,
press the “-” button
below the desired digit.
The range of allowable
addresses is from 001 to
251 (leading zeros must
be used).
If the VPM is located at
the end of the HNET
network (Style 4 only),
the termination switch
must be set to ON.
Otherwise it must be set
to OFF.
To enable Port 2 (RS-232),
the Port 2 Select pins (6
and 7) must be jumpered
on the Port 2 RS-485
connector.
