Tropos 4210 MetroMesh Router Installation Guide 2
Selecting Locations
Tropos 4210 routers are radio devices, and as such, they are susceptible to common causes of
interference that can reduce throughput and range. To ensure the best possible performance,
follow these basic guidelines:
Install antennas on the highest area of the vehicle (roof).
If the vehicle has a light bar, install antennas at least three feet away from the bar.
It is desirable to have the antenna cables as short as possible.
Install the router away from other possible sources of 2.4 GHz WLAN interference, such as
cordless phones, spy cameras, frequency hopping (FHSS) and DSSS LAN transceivers
(non-802.11g), electronic news gathering video links, radars, amateur radios, land mobile
radio services, local government sites (such as law enforcement), fixed microwave services,
local TV transmission and private fixed point transmitters).
The router is not weather-proofed, so install only in protected interior locations.
Choose a splash-resistant mounting surface that is at least 13 inches by 8 inches to provide
sufficient space to screw the router into the surface. See FIGURE. It is not necessary to level the
unit.
Preparing for Installation
The Tropos 4210 router contains integral ESD protection and vehicle power conditioning, so
external protection is not required.
Antenna Options
You can purchase any of the Tropos-approved, cable-attached antennas that are listed in
“Ordering Information” on page 17. Omni-directional antennas are best for systems requiring a
signal distribution in more than one direction. To comply with regulatory RF exposure limits,
locate antennas a minimum distance of 7.9 inches (20cm) from people. It is possible to use a
single antenna; however, two antennas are strongly recommended.
Note
Only use antennas that are approved by Tropos. Operating the unit with non-qualified
antennas is a violation of U.S. FCC Rules Part 15.203(c), Code of Federal Regulations, T itle
47.
Tropos 4210 MetroMesh Router Installation Guide 3
Preparing for Installation
Note
The device and the antennas must not be co-located or operate in conjunction with any
other antenna or transmitter.

RF Planning Guidelines
Tropos wireless routing technology is embedded in each Tropos 4210 MobileMesh router,
allowing each router to work in almost any environment and with a wide range of network
topologies. To maximize coverage range, locate the router in wireless-friendly areas. Try not to
place them in areas that can block or interfere with transmission. 802.11g devices transmit in the
2.4 GHz frequency spectrum. This spectrum is shared by devices such as microwave ovens,
portable phones, intercom systems and wireless alarm systems. Place each router in a location at
least 15 to 20 feet from any other transmitter to prevent the possibility of interference.

Cable Connections and Power
Figure 3 shows the power and connector ports on the side panel of the Tropos 4210 router:
The status indicator is red when the router is plugged in and has power. It is green when the
router has a working IP address and network connectivity.
The Ethernet Management (MGT) port is used to connect the router to the laptop computer
that is used for network access. The LAN port is not currently used for the Tropos 4210
router.
There are two USB ports, either one of which can be used to connect a GPS receiver.
There are two RS-232 serial ports, one of which can be used to connect to a client PC. One
RS-232 port is reserved for factory use.
The fuse is user replaceable (see “Fuse Replacement” on page 11).
The power plug accepts #18AWG wire.
The Tropos 4210 router is desi gned to be used with negative ground systems, such as motor
vehicle power. There is no internal battery back-up, so the vehicle must be powered for the
router to operate.
Preparing for Installation
Note
The Tropos 4210 router does not have a power switch. The router is powered when the
power plug is attached and then connected to vehicle power. To remove power from an
installed router, remove the power plug, remove the fuse, or turn off vehicle power.

Installing the Tropos 4210 MetroMesh Router
Follow these steps to install the Tropos 4210 router:
1. Remove the router from the shipping box.
2. Drill four holes with a 7, 8, or 9 drill bit to create 0.203-inch holes in the mounting surface.
Refer to Figure 4 for the mounting dimensions.

6. If you plan to use a GPS receiver, mount the receiver according to the instructions shipped
with the receiver. Connect the receiver cable to one of the USB ports on the router.
7. Use a small flat-head screw driver, if necessary, to remove the screws that attach the 2-pin
power plug to the router.
8. For vibration security, use the ziptie to secure the RJ45 and USB connectors.

is powered as soon as the plug is connected and the other ends of the power wires are
attached to vehicle power.
Remote Indicator
The Mesh Link Remote Indicator is a optional indicator that allows a user to determine whether
the Tropos 4210 router is connected to the Tropos network without looking at the status LED.
The indicator is assigned to pin 9 of the bottom Factory Use Only serial connector.
The Mesh Link Remote Indicator functions as follows:
If the 4210 is not connected to the network: (the router is booting or off, or there is no RF
signal), pin 9 is electrically disconnected from pin 5 (ground). This state corresponds to the
status light being off or red.
If the 4210 is connected to the network, pin 9 is electrically connected to pin 5 (gro und).
This state corresponds to the status LED being green)
It is a customer decision how the remote indicator should be used. Customers can set up a
custom LED indicator to show that the unit is connected, or they can connect the indicator to a
general load that turns on another device when the Tropos 4210 router is connected to the
network. In either case, installing and operating the indicator requires knowledge and skill in
basic electronics, wiring, and cable assembly. Figure 8 is a schematic drawing of the indicator.

Caution
Voltage on pin 9 must always be greater than the voltage at pin 5 (ground). Pin 5 is
electrically connected to the chassis ground (negative ground). Maximum current from
pin 9 to pin 5 is 50mA. Maximum voltage on pin 9 at any time is 32V (the same as for
the Tropos 4210 router.) Exceeding these maximums can damage the remote indicator.

Service Instructions
This section contains service information for the Tropos 4210 router.
Resetting the Router
To perform a hardware reset of the router, unplug the router, pull the fuse out, or turn off the
vehicle power. Wait 10 seconds and then reconnect the plug, fuse, or vehicle power.
Tropos 4210 MetroMesh Router Installation Guide 10
To reset the router configuration to factory defaults, use the Tropos Configuration Utility, as
described in the Tropos Networks User Guide.
Fuse Replacement
The fuse is located to the right of the power plug. The transparent red color enables you to detect
when the fuse has blown. Use needle-nose pliers or a fuse puller to pull the fuse out. Push the
new fuse firmly into the fuse socket. To confirm that the new fuse is working, check the status
light on the left side of the panel (see Figure 9).
