The Automotive EN-2000™ Router
Hardware Description and Installation
he chassis for the automotive EN-2000™ router connects to a standard 12-volt or
24-volt automotive battery, and can be used in cars, buses, trucks, and heavy
equipment. This special router provides all the features of the standard EN-2000™
router.
The automotive EN-2000 is based on the hardened version of the EN-2000, with
RS232 and RS485 ports for supervisory control and data acquisition (SCADA).
There are several uses for the automotive EN-2000. Some examples are:
• Connection of SCADA systems for refrigeration in cold-food-distribution trucks
• WiFi connection for cellphones and tablets, to secure back-end databases for
emergency-service vehicles and personnel, such as police, fire, and ambulance
• Digital video recording (DVR), to provide quick reference to recent streaming
video (for example, incident review) or to provide information on the recording
system itself (for example, the amount of remaining storage), in buses and
coaches
• WiFi and internet access to management systems for drivers of trucks and heavy-
duty vehicles
• WiFi for passengers in buses and coaches

•Section C.2, Installing the Automotive EN-2000 Router in a Vehicle, on page 3
•Section C.3, Connecting the Automotive EN-2000 Chassis to Automotive Power,
on page 3
Note: The automotive EN-2000 is configured as the standard EN-2000 is configured.
See the EN-2000™ Reference Manual for a list of documents discussing
configuration.
In addition, see the document Setting the Ignition Power-Off Delay for the
Automotive EN-2000™ Router.

C.1 Automotive EN-2000 Router Hardware
Description
See the following:
•Section C.1.1, Front Panel of the Automotive EN-2000 Chassis, on page 2
•Section C.1.2, Back Panel of the Automotive EN-2000 Router, on page 3
C.1.1 Front Panel of the Automotive EN-2000 Chassis
Figure C-1 shows the faceplate for the automotive EN-2000 without serial ports.
Figure C-1. EN-2000 Front Panel without Serial Ports
The front of the automotive EN-2000 router’s chassis without serial ports has:
- One LED for power status (PWR)
- One LED for system status (SYS)
- One LED for data activity (ACT) on the LAN port or WAN port
- LEDs to indicate cellular wireless activity (CELL) and network status (NET)
- Two RJ45 Ethernet ports (LAN and WAN)
- A slot for a SIM
- Two SMA connectors for antennas to support cellular wireless modules
- One reset switch (for default software/configuration load)
•Figure C-2 shows the faceplate for the automotive EN-2000 with two serial
ports (an RS232 port and an RS485 port).
Figure C-2. EN-2000 Front Panel with Two Serial Ports
The front of the automotive EN-2000 router’s chassis with two serial ports has
all the ports that the chassis without serial ports has. The chassis with serial
ports also includes the following ports:
- One RS485 serial port
- One RS232 serial port
Note: Figure C-2 shows a slot for a second SIM.

C.1.2 Back Panel of the Automotive EN-2000 Router
The EN-2000 automotive chassis has a special backplate to accommodate
connection to an automotive battery. Figure C-3 shows the backplate for the
automotive EN-2000.
Figure C-3. Automotive EN-2000 Back Panel
The back of the automotive EN-2000 router has:
• One DC power connector
Note: The voltage range (9–32 volts) is specified above the DC connector.
The automotive EN-2000 connects to an automotive battery.
The automotive EN-2000 has built-in protection against transient voltages.
If a transient voltage lasts more than 600 milliseconds, the unit shuts down.
When the fault is removed, the automotive EN-2000 automatically restarts in
approximately 20 seconds.
• Two reverse-polarity SMA connectors for WiFi antennas
Note: LEDs for power, system status, and network activity are on both the
front and the back of the router, for the operator’s monitoring convenience.
C.2 Installing the Automotive EN-2000 Router in
a Vehicle
Consult your Encore Networks, Inc., sales representative to determine whether
to use DIN brackets or right-angle brackets to mount the automotive EN-2000 to
vehicles in your fleet. Connect the automotive EN-2000’s ports for their network
functions.
Note: For general discussion, see the EN-2000™ Quick Installation Guide.
Installation of the automotive EN-2000 router will vary a bit from the standard
installation, particularly in power connection.
C.3 Connecting the Automotive EN-2000 Chassis
to Automotive Power
See the following:
•Section C.3.1, Making a Permanent Connection to the Automotive EN-2000,
on page 4
•Section C.3.2, Using a Temporary Connection to the Automotive EN-2000 for
Testing and Evaluation, on page 6
Page C-4 EN-2000™ Reference Manual, Document C
C.3.1 Making a Permanent Connection to the
Automotive EN-2000
The automotive EN-2000 uses a permanent power connection to your
automobile’s battery.
Note: Encore Networks, Inc., provides the connectors for the automotive
EN-2000’s RS485 serial port and its DC power input port. The customer will need
to build the cables for those connections.
Figure C-4 through Figure C-6 illustrate the connections from an automotive
battery to the automotive EN-2000 chassis:
•Figure C-4 (on page 5) illustrates Automotive EN-2000 Power Connection with
Immediate Power-Off.
•Figure C-5 (on page 5) illustrates Automotive EN-2000 Power Connection with
Delayed Power-Off.
•Figure C-6 (on page 6) illustrates Automotive EN-2000 Power Connection with
Power Always On.
The diagrams use the following key:
IGN Ignition detect. This should be connected to vehicle ignition or to an
external switch.
If IGN is connected to GND or is left open, the automotive EN-2000
turns off.
If IGN is connected to main power, the automotive EN-2000 turns on.
– Automotive EN-2000 ground (GND): Connect this lead to the
automotive battery’s negative lead.
BAT Automotive EN-2000 main input power: Connect this lead to the
automotive battery’s positive lead.

C.3.2 Using a Temporary Connection to the Automotive
EN-2000 for Testing and Evaluation
For quick testing and evaluation, the automotive EN-2000’s DC connector can use
a temporary connection to one of the automobile’s 12V accessory sockets
(formerly called cigarette-lighter outlets).
Contact your vendor for the adapter cable to connect the automotive EN-2000’s
DC connector to a 12V accessory socket. The tip of the adapter plug for the 12V
accessory socket is positive (+); the wings (on the side of the plug) are
negative (–). If that cable is not available, the customer will need to build the
cable.
Warning: Connection to the 12V accessory socket is only for quick testing
purposes. That connection quickly drains the automotive battery. If your
organization chooses to use a temporary connector to a 12V accessory socket,
set up that connection for immediate shut-off when the vehicle is not in use.
Encore Networks, Inc., does not endorse installation of an automotive EN-2000
via connection to a 12V accessory socket.
