1. Overview
The Bullet enables existing wired HART field devices to communicate with host
applications by means of WirelessHART™ technology. The Bullet is installed
permanently by screwing it directly into an available spare port of HART field device, or
using a short, right angle elbow conduit. Other installation options are possible anywhere
on the loop using a junction box or T-fitting. A wired HART field device retrofitted with a
Bullet communicates its PV over the existing wiring to DCS and simultaneously
communicates diagnostic and alarm data over the WirelessHART network to process
management, asset management and engineering applications. The Bullet has options
for power scavenging or local/direct power. The Bullet when powered by the current
loop saves users the long term cost of battery maintenance, replacement and disposal
programs. The Bullet Local/Direct power option can be used when the field device is
powered either by a power supply or an external battery/solar system. In the case of
external battery power, the Bullet provides battery power management by cycling the
field device power and taking periodic readings.
Typical Use Cases
•Upgrade legacy wired HART analog only field devices with WirelessHART
communication capability to enable 24/7 monitoring of alarms and diagnostic
information
•1-Port WA is the preferred housing for explosion proof conduit applications
•Low cost / low risk means to test and evaluate WirelessHART networks in a plant
•Substitute for multiplexers or legacy DCS upgrade to HART enabled IO.
•External Battery powered wireless remote I/O data collection
Features
•HART 7.1 Registered with HCF = fully HART compliant for communication reliability
when the WirelessHART test suite is available
•Loop powered – no batteries or other power sources required
•Connects directly to HART field device and optionally anywhere on the 4-20 mA
control loop
•MACTek patent pending StepVolt™ technology sets insertion voltage in steps from 1
to 2.5 volts to optimize trade off between available loop power and Wireless
communication bandwidth
•Direct Power option when local DC power is available: system power, external
battery/solar system
oInternal 250 ohm loop current sense resistor provided, configurable by
WirelessHART command.
oIn Direct Power mode, can switch field device on/off to take periodic readings
to save power.
•Multidrop support for up to 6 devices
•300 meters open air range

Basic Operation
The Bullet WirelessHART Adapter allows legacy wired-HART devices to be connected to
a WirelessHART network. This allows remote access to diagnostic data, digital process
variables, and alarm data stored inside HART devices.
The Bullet has both a wireless interface to communicate with the WirelessHART network
and a wired-HART interface which is connected to a traditional 4-20mA current loop.
The Bullet communicates as a wired-HART master to connected HART devices on the
loop, and can transmit and receive HART data from these connected HART devices to
the WirelessHART network. The Bullet also supports being configured like a wired-
HART slave device, so traditional HART configuration tools (such as HART Field
Communicators and PCs with HART modems) can be used to configure the Bullet.
In WirelessHART terminology, any wired-HART devices that can be communicated with
from a WirelessHART Adapter is known as a sub-device. A single Bullet WirelessHART
Adapter can support up to six wired-HART sub-devices connected to it. The
WirelessHART Gateway maintains a list of all of the devices in the WirelessHART
network, including sub-devices connected to WirelessHART Adapters. Host applications
that communicate with the WirelessHART gateway can communicate directly with the
wired-HART sub-device, and the WirelessHART gateway and WirelessHART Adapter
will transparently handle the message translation.
WirelessHART supports publishing of data from devices to the WirelessHART Gateway
on a periodic basis. This is called “burst mode” in HART terms, but is much more
advanced than the “burst mode” traditionally supported by HART devices. Data can be
burst based on an update time or when the specified process value causes a trigger that
has been configured to trip - such as when the process value rises above a certain point.
When the Bullet is configured in burst mode, it supports all of these advanced modes on
behalf of any wired-HART sub-devices that are connected. Burst mode is also very
useful to publish device status data (such as malfunctions or alarms) to the Gateway on
a periodic basis or immediately when a critical event occurs.
Typical Usage
In most network configurations, the Bullet will be used in conjunction with a wired-HART
sub-device and will be configured to publish process data and device status data from
the sub-device to the WirelessHART network on a periodic basis (such as every 8
seconds or every minute, etc).
The Bullet adds several features to make this typical usage mode very easy to configure,
such as the Automatic Sub-Device detection and Automatic Burst mode configuration.

Power
The Bullet WirelessHART Adapter has been designed to be extremely power efficient
and flexible to allow for a wide variety of installation options.
Loop Powered Mode
The Bullet can be wired in series with devices on a 4-20mA loop and be powered from
the loop. The Bullet utilizes MACTek’s patent pending StepVolt™ technology, to allow
the user to set this insertion voltage drop between 1.0 – 2.5 Volts, in 0.5 Volt increments.
StepVolt™ allows users to select the best insertion voltage drop for their application.
The higher the voltage drop setting used, the more WirelessHART messages the Bullet
will be able to transmit and receive.
In applications where there is very little voltage overhead in the loop, such as
transmitters on very long cable runs or with IS barriers, StepVolt™ allows the selection
of a low insertion voltage drop. However in a number of applications there is plenty of
voltage overhead on the loop to allow for a high voltage insertion drop from the Bullet.
A concern with a loop powered WirelessHART Adapter is being able to operate under
worst case conditions since very little power is available to be used by the Adapter at low
loop current conditions. The Bullet is designed to operate at the worst case operating
conditions at all power settings and will respond to Wired or WirelessHART commands.
The Bullet will operate as specified with reliable communications even under the
following conditions:
- Loop current of 3.2mA and 1.0V insertion voltage drop
- Temperature Extremes (-40C to +85C)
- Worst Case wired-HART communication on the loop. Constant wired-HART
communication addressed to the Adapter and the Adapter responding to every
command.
- Every WirelessHART timeslot filled and transmitting
Note: On power-up, the voltage drop will be set to 1.0V until the Bullet has finished
initialization. At this point, it will change the voltage drop to the value specified.
NOTE: The Bullet cannot control the loop current, if connected in loop-powered mode
there must be something controlling the loop current, such as a 4-20mA transmitter.
StepVolt™ Benefits
The benefit to using a high StepVolt™ setting is that the Bullet will be able to support a
much higher amount of WirelessHART packets per second. Even if the particular device
attached to the Bullet is configured for a very low update rate, being able to support a
high amount of WirelessHART packets per second helps the overall WirelessHART
network operation.

WirelessHART is a mesh network – each node in the network will route messages on
behalf of other nodes in the network. This is done to expand the overall range of the
network and also for the data reliability of the network by forming multiple redundant
paths. By setting the Bullet to a high StepVolt™ setting, more WirelessHART packets
can be routed through the Bullet for other nodes in the network.
Another consideration from a WirelessHART network standpoint is that many devices in
a WirelessHART network are battery powered and all wireless transmissions performed
by these devices impact their battery life. The more WirelessHART devices that a
battery powered node has to route messages for, the shorter its overall battery life is.
The Bullet is different – since it is loop powered it can support wireless messages
indefinitely without any concerns of battery life. By placing MACTek Bullet’s at key
locations in a WirelessHART network, such as places that route messages for other
WirelessHART nodes, this routing function can be offloaded from battery powered nodes
to the Bullet and help to preserve their battery life of the battery powered nodes.
StepVolt Setting WirelessHART Packets per Second

2.5V 26.66
Note: The value shown in WirelessHART Packets per second column is the value
reported back in HART Command 777. These values are preliminary and subject to
change.
Recommendation: Plan on using the highest StepVolt™ setting possible to help the
overall WirelessHART network performance.
Direct Powered Mode
In direct powered mode, the Bullet can be powered by an external DC supply.
The DIRECT POWER connections are DIRECT POWER, black lead wire, to the positive
potential and the RETURN, white lead wire, to the negative terminal of the external DC
source. The voltage range of this input is 7VDC to 32VDC.
External Power Source Mode
The Bullet can be powered by an external DC power source such as; battery, solar panel
and control power to the Field device.

2. Configuration
This section contains information on configuration that should be performed prior to
installation of the Bullet in the field.
Initial configuration is performed through the use of a HART Device Descriptor (DD) for
the Bullet over the wired-HART connection. Once connected to the WirelessHART
network, configuration changes can be made using the DD over either the wired-HART
interface or the WirelessHART interface.
Bench Top Configuration
Power the Bullet. This can be performed by connecting the bench power supply positive
terminal to the “Direct Power” input wire and the power supply negative terminal to the
“Return” wire.
Connect HART communicator or HART modem to the Bullet. Connect one lead of the
HART modem to the “Return” wire of the Bullet and the other lead of the HART modem
to the “HART“ wire of the Bullet. The HART signal connection is polarity independent.
NOTE: By default, the Bullet is at HART polling address 15.
NOTE: By default, all WirelessHART Adapters are configured as a primary HART
master. The HART communicator used to configure the Bullet should be configured in
Secondary HART master mode.

Detailed Settings
HART Dynamic Variables
The Bullet appears as a HART device on both the wired-HART and WirelessHART
networks, and supports four HART dynamic variables. These can be read using
standard HART commands and are displayed in the Bullet DD.
HART Variable WirelessHART Packets per Second
Primary Variable (PV) Loop Current (mA)
Secondary Variable (SV) Direct Power Voltage (V)
Tertiary Variable (TV) Internal Temperature (C)
Quaternary Variable (QV) Storage Voltage (V) (Internal to the Bullet)
Configure Power Mode (method)
The Configure Power Mode DD Method guides the user through the selection of the
proper power mode settings for their configuration.
Adapter Power
By Default, the Bullet is configured for loop powered operation with a 1.0V insertion
voltage drop. Through the DD, the power setting can be changed to set the insertion
voltage drop to 1.0V, 1.5V, 2.0V or 2.5V. The power mode setting can also be set to
several different direct power modes.
Adapter Power Setting WirelessHART Packets per Second
Loop Powered - 1.0 V 5.79
Loop Powered - 1.5 V 12.65
Loop Powered - 2.0V 19.66
Loop Powered - 2.5V 26.66
Direct Powered – Max Bandwidth 101.40
Direct Powered – Power Save 26.66
Note: The value shown in WirelessHART Packets per second column is the value
reported back in HART Command 777. These values are preliminary and subject to
change.
Loop Powered
This allows for different StepVolt™ settings to be selected when operating in a loop
powered mode.

MACTek BULLET™ – User Manual
DM1101010UAB
Copyright 2009-2010 12 of 33
Direct Powered – Max Bandwidth
This allows for the maximum WirelessHART bandwidth possible and assumes that the
direct power source can supply maximum power.
Direct Powered – Power Save
This assumes that the direct power source is limited and will limit the amount of
WirelessHART packets to a small amount to conserve power
Note: The Bullet will power up and begin to operate with any valid power installation,
regardless of what the Adapter Power setting is configured as. This allows for the user
to change this setting even if it is configured incorrectly, however any changes to this
should be performed before the Bullet has joined the WirelessHART network. If this
power setting set different than how the Bullet is actually powered (such as a Direct
Powered setting is selected but the unit is actually loop powered), the system operation
is not guaranteed and it is possible that the Bullet will reset due to insufficient power
once connected to the WirelessHART network.
Note: The unit can be both Direct Powered and wired in series with the loop. When
configured in any of the Direct Powered modes, there will be an insertion voltage drop of
1.0V if the Bullet is also wired in series with the loop.
Field Device Power Control
When used in a direct power configuration, the Bullet can activate a switchable
terminating resistor between the HART and the RETURN signal wires. This can
eliminate the need for an external terminating resistor in some installation and also
allows for the field device power to be switchable and controlled automatically by the
Bullet.
The parameter “Field Device Power Control” can be set to three different states: Off, On,
or Switching.
Off: The Field Device Power Control switch is never connected
On: The Field Device Power Control switch is always connected
Switching: The Bullet will automatically control the operation of the Field Device Power
Control switch.
Field Device Power Control – Switching Mode
When the Bullet is used in the “Field Device Power Control Switching” mode, the Bullet
will control this switch to power on and off HART Field Devices as needed by the
network operation. This is useful when running off a limited power source, such as an

MACTek BULLET™ – User Manual
DM1101010UAB
Copyright 2009-2010 13 of 33
external battery or solar cell, and can be used to power off the HART field devices
between measurements.
When used in combination with Burst mode, the Bullet will schedule measurements from
the HART devices connected, and will turn on the loop when a scheduled measurement
is needed. After all the measurements have been read from the connected HART
devices, the Bullet will power off the devices by turning off the “Field Device Power
Control” switch.
For this mode to work properly, the user needs to determine and configure the “Power
On Time” parameter for the connected wired HART field devices.
Field Device Power On Time: The time in seconds that a HART field device needs to
be powered on in order to obtain an accurate measurement.
Note: Improper selection of the “Power On Time” parameter can lead to a field device
reporting measurements outside of the published tolerances for the device. Consult the
field device documentation or contact the field device vendor to determine this
information.
Field Device Idle Time: The time in seconds that the field device will remain powered
after an unscheduled event. This event could be a HART query over the WirelessHART
handheld or detection of another HART master trying to communicate (such as a wired
HART handheld). This parameter prevents the Bullet from powering off a field device
when some other master is attempting communication with the field device. This
parameter can generally be left at the default of 60 seconds.
Field Device Estimate On Percentage: This is the estimated time that the field device
will be powered during normal operation. This is a calculation based upon the Field
Device Power On Time and the Burst mode settings of the Bullet. The lower this value
is, the less amount of power will be used.
Join Device to Network (method)
The Join Device to Network DD Method guides the user through entering in the
WirelessHART network ID and join key, and starting the WirelessHART join procedure.
Network ID
The Network ID is the ID of the WirelessHART Network to join.
Join Key
The Join Key is a 32 character hexadecimal password (broken into four 8 character
blocks) which is used to get access to the WirelessHART network.

Radio Output Power
The transmit power of the Bullet’s radio. Can be set to either 0dBm or +10dBm.
HART Polling Address
This is the HART polling address that is used to communicate to the Bullet on the wired-
HART interface using a HART capable host (such as a HART communicator or PC with
HART modem).
By Default, the Bullet is at HART polling address 15. Through the DD, the polling
address can be set to any value between 0 and 63.
HART Master Mode
This is the HART Master mode used by the Bullet when it is communicating as a HART
master with wired-HART devices.
By Default, the Bullet is configured as a HART primary master. Through the DD, the
master mode can be changed to be either a HART secondary or primary master.

MACTek BULLET™ – User Manual
DM1101010UAB
Copyright 2009-2010 15 of 33
HART Retry Count
This is the amount of retries the Bullet will attempt when communicating as a HART
mater to wired-HART devices.
By Default, the Bullet is configured to use 3 retries. Through the DD, the retry count can
be set to 2, 3, 4 or 5.
HART Number of Response Preambles
This is the amount of preambles the Bullet will use when responding to HART
commands sent by a HART master (such as a HART communicator or PC with HART
modem) on the wired-HART connection.
By Default, the Bullet is configured to use 5 preambles. Through the DD, the response
preamble count can be set between 5 – 20 preambles.
Write Protect
This setting allows the configuration inside of the Bullet to be write protected. The write
protect setting is controlled through the DD.
By Default, the Bullet is configured to have write protect disabled. Through the DD, the
write protect setting can be enabled or disabled.
Sub-Device Time Synchronization
If a HART 7 or greater sub-device is detected and it supports a real-time clock, the Bullet
can synchronize the sub-device time with the WirelessHART Network time if this setting
is enabled. If the sub-device does not support a real-time clock, this setting has no
effect. This synchronization will be performed when the Bullet joins the WirelessHART
network and then once per day.
Sub-Device Scan on Power-up
When Sub-Device Scan on Power-up is enabled, the Bullet will scan the 4-20mA loop for
attached HART devices on power-up or when the Bullet is reset. These will be added to
the list of supported sub-devices for the Bullet and will be communicated with the
WirelessHART gateway.
NOTE: The sub-device scan is only performed after a power-up or reset of the Bullet. If
wired-HART devices are added to the loop after the Bullet is powered, execute the Scan
for Sub-Devices method or reset the Bullet to detect them.
Within the DD, Automatic Sub-device detection can be enabled or disabled. It is highly
recommended that this mode always be left enabled.

MACTek BULLET™ – User Manual
DM1101010UAB
Copyright 2009-2010 16 of 33
If this mode is disabled, the host must support scanning for sub-devices in order for any
sub-device to be detected or you must manually execute the Scan for Sub-Devices
method. The list of sub-devices is not retained through a power-cycle or reset of the
Bullet, so the host would need to detect this and rescan for sub-devices.
NOTE: The Bullet can support a maximum of eight sub-devices. If more than eight
wired-HART devices are detected, only the first eight devices will be used.
Scan Start Address
This is the first HART polling address that will be used when a scan for Sub-devices is
performed.
Scan Stop Address
This is the last HART polling address that will be used when a scan for Sub-devices is
performed.
Scan for Sub-Devices (method)
The Scan for Sub-Devices DD method will perform a scan for sub-devices connected to
the Bullet, across the HART polling addresses defined.
This method allows for the existing sub-device list to be either retained or erased prior to
the new scan.
Automatic Burst Mode Configuration
When Automatic Burst Mode Configuration is enabled, the Bullet will automatically
configure burst messages for Bullet itself and all of the connected sub-devices.
The Automatic Burst Mode Configuration setting can be set from within the DD, and
allows the user to select several different fixed update rates (1 second, 2 seconds, 4
seconds, 8 seconds, 16 seconds, 32 seconds, 1 minute, 2 minutes, 5 minutes, 10
minutes, 30 minutes, 60 minutes) at which all of the burst messages will be published to
the WirelessHART gateway.
If this mode is disabled, burst mode can be configured manually using the DD.
NOTE: If the Automatic Burst Mode Configuration setting is set, this will override any
manual configuration of the burst mode settings. If any manual burst mode settings are
configured, Automatic Burst Mode will be automatically turned off.

Alerts
The Bullet will detect and log system events to alert the user when something has
occurred that could effect system operation.
Note: All Alerts are also mapped into HART Command 48 status bits.
Active Alerts
The condition that caused the alert is still present. Active alerts cannot be cleared -
corrective action must be taken to eliminate the alert, such as modifing some external
source of the event (such as the power supply) or by changing an incorrect setting in the
Bullet.
Alert History
The condition that cause the alert is no longer present, or the alert is a one time event.
The start timestamp indicates when this alert first occurred and the stop timestamp
indicates when the alert stopped (or the last time the alert was detected).
