This QUICK START guide will walk you through the setup and process required to access the
WebUI configuration window and to establish a basic wireless connection to your carrier.
Note that the units arrive from the factory with the Local Network setting configured as
‘Static’ (IP Address 192.168.168.1, Subnet Mask 255.255.255.0, and Gateway
192.168.168.1), in DHCP server mode. (This is for the LAN Ethernet Adapter on the back of
the BulletPlus unit.)
2.1 Installing the SIM Card
Before the BulletPlus can be used on a cellular network a valid SIM Card for your Wire-
less Carrier must be installed. Insert the SIM Card into the slot as shown, the bottom
SIM slot is for SIM1: (The contacts should face down, and the notch to the right)
To reset to factory
defaults, press and hold
the CFG button for 8
seconds with the
BulletPlus powered up.
The LED’s will flash
quickly and the modem
will reboot with factory
defaults.
Use the MHS-supplied
power adapter or an
equivalent power source.
The unit can also be powered
via PoE using a MHS PoE
injector.
2.2 Getting Started with Cellular
Connect the Antenna’s to the applicable ANTENNA jack’s of the BulletPlus.
Connect the power connector to the power adapter and apply power to the unit, the CPU
LED will flash during boot-up, once on solid, proceed to the next step.
On the Carrier > Status Tab, verify that a WAN IP Address has been assigned by your
carrier. It may take a few minutes, so try refreshing the page if the WAN IP Address
doesn’t show up right away. The Activity Status should also show “Connected”.
If you have set a static IP on your PC, you may need to add the DNS Servers shown in
the Carrier Status Menu to you PC to enable internet access.
Congratulations! Your BulletPlus is successfully connected to your Cellular Carrier.
Ensure the default
passwords are changed.
Set up appropriate firewall
rules to block unwanted
incoming data.
To access devices connected to BulletPlus remotely, one or more of the following must be
configured: IP-Passthrough, Port Forwarding, DMZ. Another option would be to set up a
VPN.
Ensure that all default passwords are changed to limit access to the modem.
(Firmware version v1.3.0-r1014 requires the defaults passwords are changed
upon initial login).
For best practices and to limit data charges it is critical to properly set up the
firewall. (Especially important for Public Static IP addresses.)
The BulletPlus is a fully-enclosed unit ready to be interfaced to external devices with standard connectors
as discussed below. An optional mounting bracket can be ordered to allow the BulletPlus to be mounted

Maintenance - Remote firmware Upgrades, reset to defaults, configuration backup
and restore.
Reboot - Schedule reboots and/or immediately reboot the system.
4.1.1 System > Summary
The System Summary screen is displayed immediately after initial login, showing a summary and status of
all the functions of the BulletPlus in a single display. This information includes System Status, Carrier
Status, Cellular & LAN/WAN network information, version info, etc.
The System Summary page
will Auto Refresh, each time
this happens a small amount
of data is used. If viewing
over the Cellular Network this
data could add up to a
significant amount over a long
period of time.
Options available in the System Settings menu allow for the configuration of the Host Name, Description,
Console Timeout and System Log server settings.
Image 4-1-2: System Settings > System Settings
Host Name/Description
The Host Name is a convenient identifier for a specific BulletPlus unit.
This feature is most used when accessing units remotely: a convenient
cross-reference for the unit’s WAN/Carrier IP address. This name
appears when logged into a telnet session, or when the unit is
reporting into Microhard NMS System.
The description provides an additional field for text characters, but is
not displayed anywhere but in this field.
Console Timeout (s)
This value determines when a console connection (made via Console
Port or Telnet) will timeout after becoming inactive.
CFG Reset to Default Button
Enabled by default, when the CFG button on the front of the BulletPlus
is held down for 10s while the unit is powered up, the unit will reset
and all settings will be reset to factory defaults. When disabled the unit
will reset, but the settings will not be overwritten.
Network Time Protocol (NTP)
can be used to synchronize the
time and date or computer
systems with a centralized,
referenced server. This can
help ensure all systems on a
network have the same time
and date.
The BulletPlus can report system level events to a third party Syslog
server, which can be used to monitor events reported by the BulletPlus.
IP Address
0.0.0.0
System Syslog Server Port
Enter the UDP listening port of the Syslog Server. The default port number
is generally 514, but could vary from Server to Server.
Time Settings
The BulletPlus can be set to use a local time source, thus keeping time on its own, or it can be configured
to synchronize the date and time via a NTP Server. The options and menus available will change
depending on the current setting of the Date and Time Setting Mode, as seen below.
UDP Port
514
Select the Date and Time Setting Mode required. If set for ‘Use
Local Time’ the unit will keep its own time and not attempt to
synchronize with a network server. If ‘Synchronize Date And
Time Over Network’ is selected, a NTP server can be defined.
The calendar date may be entered in this field. Note that the
entered value is lost should the BulletPlus lose power for some
reason.
The time may be entered in this field. Note that the entered
value is lost should the BulletPlus lose power for some reason.

NTP Client Interval
By default the modem only synchronizes the time and date during
system boot up (default: 0), but it can be modified to synchronize at a
regular interval. This process does consume data and should be set
Certain services in the BulletPlus can be disabled or enabled for either security considerations or resource/
power considerations. The Enable/Disable options are applied after a reboot and will take affect after each
start up. The Start/Restart/Stop functions only apply to the current session and will not be retained after a
power cycle.
Image 4-1-5: System > Services
The FTP service can be enabled/disabled using the Services Status
Menu. The FTP service is used for firmware recovery operations.
Using the Telnet Service Enable/Disable function, you can disable the
Telnet service from running on the modem. The port used by the
Telnet service can also be modified. The default is 23.
Using the SSH Service Enable/Disable function, you can disable the
SSH service (Port 22) from running on the modem. The port used by
the SSH service can also be modified. The default is 22.
The default web server port for the web based configuration tools used
in the modem is port 80 (http) and port 443 (HTTPS).
Change as required, but keep in mind that if a non standard port is
used, it must be specified in a internet browser to access the unit.
(example: http://192.168.168.1:8080).
The Keep alive tab allows for the configuration of the keep alive features of the BulletPlus. The BulletPlus
can check for activity on the Wireless Interface, The CLI (Command Line Interface), The WEBUI, and
ensure that they are working as expected. In the event that the BulletPlus does not detect activity on a
interface it will reboot to attempt to resolve any issues that may have occurred.
Image 4-1-6: Carrier > Keepalive
Enable or Disable the keep alive functions of the modem. If it is
disabled, the user can configure the Traffic Check separately. The unit
will monitor traffic on the Cell interface.
Monitors traffic on the Cell interface as well as the WAN interface if the
WAN port is configured as independent in the Network Settings. If the
Bullet detects that there is no activity on the above interfaces it will
attempt a ICMP, HTTP or DNS Lookup as configured below to
determine if service has been lost.
Monitors the activity of CLI. If the console isn't accessed within the
certain period which is specified by Console Timeout in SystemSettings web page, the modem will send out the connection request.
Monitors the activity of Web UI. If the Web UI isn't accessed or
refreshed within the certain period which is specified by Console
Timeout in System-Settings web page, the modem will send out the
connection request.
Once the connection is lost, the modem will send one of the requests
to the remote host to determine the connection status. If the modem
fails to get the response, it will re-send the request within the seconds
specified by Keepalive Interval below:
ICMP: Send a "ping" request
HTTP: Send a "wget" request to a HTTP server
DNS Lookup: Send a "dslookup" request to a DNS server
Specify a IP Address or Domain that is used to test the modems
connection. The modem will send out the connection requests to the
specified Host.
The Interval value determines the frequency, or how often, the unit will
send out PING messages to the Host. The BulletPlus will first attempt
to re-initialize the cellular model before performing a full system
reboot, thus the interval may be delayed by up to 120 seconds)
The Keepalive Retry is the maximum number of connection failures
such as “Host unreachable” the unit will attempt before the unit will
reboot itself to attempt to correct connection issues. The default
number is 20, and valid value is from 10 to 200.
