The microprocessors and associated circuitry within a VWG controller are sensitive
to static discharge. Follow these precautions when installing, servicing, or operating
the system:
Work in a static-free area.
Discharge any static electricity you may have accumulated.
Discharge static electricity by touching a known, securely grounded
object.
Do not handle the printed circuit board (PCB) without proper protection
against static discharge. Use a wrist strap when handling PCBs. The wrist
strap clamp must be secured to earth ground.

7 | VWG-50-Installation Manual
MOUNTING
Mount the VWG in a location that allows clearance for wiring, servicing, and antenna
removal.
Environmental Requirements
Note the following requirements for the VWG mounting location:
This product is intended for indoor use only. Do not expose the unit to ambient
conditions outside of the range of 0ºC (32ºF) to 50ºC (122ºF) and relative humidity
outside the range 5% to 95% non-condensing (pollution degree 1).
If mounting inside an enclosure, that enclosure should be designed to keep the
unit within its required operating range considering 20-watt dissipation by the
controller. This is especially important if the controller is mounted inside an
enclosure with other heat producing equipment.
Do not mount the unit:
– In an area where excessive moisture, corrosive fumes, or explosive vapors
are present.
– Where vibration or shock is likely to occur.
– In a location subject to electrical noise. This includes the proximity of
large electrical contractors, electrical machinery, welding equipment, and
spark igniters.
Physical Mounting
The following information applies about physically mounting the unit.
You can mount the VWG in any orientation. It is not necessary to remove the
cover before mounting.
Mounting on a 35mm wide DIN rail is recommended. The VWG unit base has a
molded DIN rail slot and locking clip.
If DIN rail mounting is impractical, you can use screws in mounting tabs on the
VWG
The following procedure provides step-by-step DIN rail mounting instructions for the VWG.
Mount the VWG prior to mounting any accessory items.

8 | VWG-50-Installation Manual
Procedure 1 - To mount on DIN rail
Step 1 Securely install the DIN rail using at least two screws, near both ends of the
rail.
Step 2 Position the VWG on the rail, tilting to hook DIN rail tabs over one edge of the
DIN rail
Step 3 Pull out the DIN rail clip and push down and in to force the DIN rail clip to snap
over the other edge of the DIN rail.
Step 4 To prevent the VWG from sliding on the DIN rail, secure with clips provided by
the DIN rail vendor, or place a screw in one of the four mounting tabs in the
base of the VWG.

VWG-PS-AC 120 VAC WALL MOUNTED POWER SUPPLY
Both the U.S. and International models of wall power modules are self-contained
switching power supplies designed to plug into a standard building power receptacle of
appropriate voltage. To supply power to the VWG, you then simply plug the coaxial
connector from the VWG-PS-AC into the coaxial power connector on the VWG base
board.
Power Wiring
Only VWG-PS-DC and VWG-PS-AC power supply
with factory installed ferrite on the power cord can
be used with the VWG. The usage of another non-
approved power supply may void the FCC
compliance of the VWG and wireless controllers.
Connect power cord as showed into
coaxial connector.
Do not plug the coaxial connector from the power supply into
the VWG until all other mounting and wiring is completed. See
“Power Up and Initial Checkout,” section.
Communications Wiring
Connect communications wiring to the VWG using Net1, Net2 or the RS-485 connection
based on VWG model used and configuration.
Note: Prior to connecting cables, provide strain relief to prevent damage to the controller.
Ethernet—BACnet™ over IP wiring
Two, female 10/100-Mbit Ethernet connections are provided on the VWG. These are RJ-45
connectors labeled NET2 and NET1. Use a standard Ethernet patch cable for connecting to
a hub or Ethernet switch. An activity LED for each Ethernet port is visible and labeled
“NET2” and “NET 1” on the cover.
Note: Typically, you only use NET1 (primary port), unless you have a specific
application for isolating a driver’s network traffic to a separate IP address (and
LAN) using NET2. In all cases, port selection can be changed and is
dependent of configuration made using the VWG configuration tool.

12 | VWG-50-Installation Manual
The packing slip accompanying the VWG will provide the “factory-shipped” IP settings for
both NET1 and NET2. Refer to the document LIT-VWG-50-SETUP-Exx for more
information for details on the default IP address and how to change it.
The supplied ferrite in the VWG packaging needs to be installed on the IP wire in
a specific way for FCC compliance. Place IP wire into the provided ferrite as shown in
diagram below and make sure to follow the placement dimension. Close and snap the
ferrite casing as shown.
Wire IP cable into NET1 or NET2 as per configuration.

13 | VWG-50-Installation Manual
RS485-BACnet™ MS-TP wiring.
An RS485, optically isolated port uses a 3-position, screw terminal connector and always
operates as COM2. Wire to this connector with shielded 8-22 AWG wiring (refer to the
TIA/EIA-485 standard). The screw terminals (from left-to-right) are shield, plus (+), and
minus (–).
The supplied ferrite in the VWG packaging needs to be installed on the MS-TP
wire in a specific way for FCC compliance. Place MS-TP wire into the provided ferrite
as shown in diagram below and make sure to follow the placement dimension. Close and
snap the ferrite casing as shown.
Wire MS-TP cable into MS-TP RS-485 connector.

14 | VWG-50-Installation Manual
A NTENNA INSTALLATION
Controller mounted antenna (VWG-WA)
All VWG-50 are supplied with a controller-mounted antenna. The
antenna is shipped loose in the controller main packaging box.
This installation type is to be used only when the controller (and
antenna) is not installed inside a closed metal enclosure and that
clear reception is expected.
Gently screw the antenna into the antenna connector at the top of
the VWG. Do not over tight the antenna.
Remote mounted antenna (VWG-RA)
If a remote mounted antenna is required because of the location of
the VWG, a separate antenna can be ordered. Part number VWG-
RA
This installation type can typically be used when the controller is
installed inside a closed metal enclosure.
Gently screw the female connection of the remote antenna into
the VWG. Remote antenna has a weighted magnetic base for
metal surface mounting. Wire length is 1.5 M (4.9 Ft)

Procedure - Initial power up and checkout
1. Connect the Backup Battery.
2. Apply Power.
3. Check the Status LEDs.
1) Connect the Backup Battery
With the cover removed from the VWG (see “Removing and Replacing the Cover,”), locate
the red and black wires coming from the backup battery, with 2-position connector plug. Plug
the connector into the battery connector on the bottom board (below option slot 2 area).
The connector is keyed—you cannot insert it incorrectly. The red (positive) connection
should be the furthest from the two 30-pin option modules connectors.
For more details on the backup battery, see “About the Battery”.

15 | VWG-50-Installation Manual
2) Apply Power
Apply power to the VWG by plugging in the power plug into either the VWG (if wall
mount AC adapter VWG-PS-AC) or the 24VAC-powered VWG-PS-DC module.
3) Check the Status LEDs
When power is applied, the green LED labeled “SYS” will light. This is a green LED. Once
the VWG boots, the yellow “BEAT” (heartbeat) LED will begin blinking, with a typical rate
of about 1 Hz. Boot time should begin within 30 seconds after power is applied.
The blink pattern of the heartbeat LED under normal operation will differ for each
installation (depending on station activity). But, in general, the LED should blink about once
per second. The rate will be slower when the control engine is executing the station
database, and as more objects / wireless controllers are added.
After applying power, if the heartbeat LED comes on (steady) and stays lit longer than
two minutes, contact technical support for assistance. See also the “Using Status LEDs”
section.
ABOUT THE BATTERY
The VWG is provided with a custom 10-cell NiMH battery pack mounted to the unit (under
the cover). This battery allows the VWG to continue operation through very short power
bumps (a few seconds in duration). If a longer power outage occurs, the battery provides
enough run time for the VWG to backup data and then shutdown. Typically, this is one
minute. Shutdown occurs automatically, after data is backed up to on-board flash
memory.
The battery is trickle-charged by the VWG during normal operation. Following an extended
power outage, the battery is charged at a faster rate. The power and battery circuitry is
monitored by the VWG. The battery should be replaced approximately every three years, or
more often if the unit is in a high temperature environment.
Note: A NiMH battery characteristic is to lose charge if not left in charge mode (trickle
charge). Leaving the battery unconnected, or in the unit powered off will cause
the battery to fully discharge in a matter of weeks. Note that in the case of a new
VWG, it ships from the factory with a completely discharged battery. Therefore,
allow at least 18 hours for the battery to charge if it has not been in a powered unit.
For more information on the use and replacement of the battery, refer to the “Required
Battery Maintenance” section.

16 | VWG-50-Installation Manual
RELATED DOCUMENTATION
For more information on configuring and using the VWG controller, consult the following
documents available from the VWG section at www.viconics.com:
Gateway BACnet™ integration guide (VWG-50-BIP & VWG-50-MSTP), is available in
document ITG-VWG-50-BAC-Exx
Information on design consideration of wireless mesh networks and VWG set-up /
diagnostics is available in document LIT-VWG-50-SETUP-Exx
STATUS LEDS
The VWG controller includes several LEDs that can help determine the status of the unit.
They are located in two places: the top of the controller (visible through the cover), and for
serial ports, on the bottom board (only with cover removed). From left-to-right these LEDs
include:
Ethernet Ports
Heartbeat
System
Wireless card communication status
Ethernet Ports
Each Ethernet port (“NET2”, “NET 1”) has one green LED, visible on the top cover. A
“NETx” LED indicates activity on that port as follows:
Off—No Ethernet link is made
On—Ethernet link is present, but no activity on the LAN
Blinking—Ethernet link is present with data activity on the LAN.
Beat
The “BEAT” LED is located to the right of the Ethernet status LEDs, and is yellow. Under
normal operation, this LED should blink about once per second. Blink patterns differ as
station activity varies, but any pulse rate from once per second to 10 blinks per minute
usually indicate normal operation. If the heartbeat LED stays on constantly, does not light,
or blinks very fast (more than once per second), contact System Engineering for technical
support.
System
The “SYS” LED is located to the right of the heartbeat (“BEAT”) LED, and is green. This
LED provides a CPU machine status check, and should remain lit whenever the VWG is
powered. If the SYS LED does not light while power is applied, contact technical support
for assistance.
Wireless card communication status
The Wireless card communication status is located right beside the wireless antenna
connection on the VWG. This LED provides a simple diagnostic status of the Viconics
wireless network.

MAINTAINING THE VWG
This section provides information on the following topics:
1. Cleaning
2. Required Battery Maintenance
3. Replacement Parts
4. Replacing the VWG base assembly
5. Returning a Defective Unit
1) Cleaning
If dust or metal filings are present inside the unit, clean with VACuum or compressed air.
Otherwise, no cleaning inside the unit is required. Optionally, if the cover becomes dirty,
you can wipe it with a damp cloth and mild detergent.
2) Required Battery Maintenance
Battery life expectancy is a function of its discharge cycles (the number of discharges and
their depth) and the ambient temperature of the battery during normal operation. In most
applications, the battery should see relatively few discharges. Therefore, ambient
temperature has more to do with determining the life expectancy of the battery than does
any other factor. If the VWG is installed in a conditioned space, the battery should provide
dependable service for approximately three years (average). In an environment where the
operating temperature is higher (that is, 50ºC or 122ºF), you should only expect the battery
to last approximately one year.
The NiMH battery in the VWG controller is fully discharged when factory shipped.
Additionally, NiMH batteries lose charge over time if not kept trickle-charged (for more
details, see “About the Battery,”). Therefore, even a new unit (or replacement battery) will
require up to 18 hours of powered operation before it can provide reliable backup power (is
at full charge).
3) Standard Replacement Parts
Standard replacement parts are listed in Table 4 and can be ordered from stock without
restriction. Standard replacement parts cannot be returned for credit and should be
disposed of in an appropriate manner.
