You need a BGAN SIM card for either BGAN M2M or BGAN class 2 services. To insert the SIM 
card, do as follows:

NOTE

: Make sure the EXPLORER 540 is 

not

 

powered when you insert or remove the SIM 
card!
1.  Open the cover for the interface enclosure 

at the back of the  
EXPLORER 540. Use the included Torx bit 
to unscrew the screws. 

2.  Locate the SIM holder in the middle of the 

compartment.

3.  Slide the lock to release the SIM holder.
4.  Lift the end of the SIM holder and insert 

the SIM card as shown.

5.  Lower the SIM card holder with the SIM 

card inserted and lock it.

6.  When all cables are connected, put the 

cover back on and tighten the screws. 

 

NOTE

: Make sure the PIN for the SIM card is 

either disabled or set up for automatic valida-
tion. For details, see the EXPLORER 540 User 
and integrator’s manual.

A pole mount kit is included in the package. To mount the EXPLORER 540 on a pole, do as 
follows:

To maintain the Ingress Protection rating of the EXPLORER 540 and to avoid cables acciden-
tally being disconnected, all cable connections are made inside the interface enclosure at the 
back of the EXPLORER 540. 
Tools:

• 

Use the provided Torx bit to open the interface enclosure at the back of the terminal 

•  Use a flat blade screw driver (max. 2 mm/ 0.08” wide) to press down the spring-loaded 

terminals

•  Use a flat blade screw driver (max. 3.5 mm/ 0.14” wide) to unscrew and fasten the screw 

terminals

1.  Lead the cable(s) through the cable gland(s) and gasket(s) (suitable for cable diameter 

5-10 mm/ 0.2”-0.4”). For C1D2 installations, use the supplied C1D2 approved cable glands. 
Make sure the cable glands fit tightly.

2.  Connect the cables according to your 

configuration. See the reverse of this 
guide for pinout, specifications and 
example configuration drawing.

 

The RJ-45 connector of the LAN cable 
can pass through the standard cable 
gland. (see picture)

3.  If you are 

not

 using PoE to power 

the EXPLORER 540, connect a power 
cable between the DC input terminals 
and a current-limited power supply 
or an external battery as described 
below. 

4.  When all cables are connected, mount the cover for the interface enclosure and tighten 

the screws with the included Torx bit.

Important

! If you only need to install one cable, mount the provided blanking plug in the 

unused hole to maintain the Ingress Protection (IP grade) of the terminal.

To connect to the DC input:

1.  Lead the cable through the cable gasket 

at the DC input.

2.  If the DC cable is shielded, insert the end 

of the 

shield

 into the screw terminal 

marked 

3-GND

 and tighten the screw to 

torque 0.5 N m/ 4.5 lbf in. 

3.  Insert the 

negative

 wire into the termi-

nal marked 

2-DCIN -

 in the DC terminal 

block and tighten the screw to torque 

0.5 N m /4.5 lbf in.

4.  Insert the 

positive

 wire into the terminal 

marked 

1-DCIN +

 in the DC terminal  

block and tighten the screw to torque 

0.5 N m/ 4.5 lbf in.

5.  Tighten the cable gland.

EXPLORER 540 User and integrator’s manual (part no. 98-148232) as well as other language 
versions of this installation guide are available for download at the Cobham SYNC Partner 
Portal. Go to www.cobham.com/satcom and select Cobham SYNC Partner Portal > Downloads.

Caution! 

Do 

not

 connect the 

positive or negative 
wire to 3-GND!  

Pole size  

1” to 1.5”

 

(33.7 to 48.3 mm)

Note:

 If the LED is steady yellow, it means the 

installation failed and there is a warning.
If you can connect a computer locally to the EXPLORER 540, you can use the web interface to 
follow the progress on screen, see any warnings, and restart the installation if necessary. See 

Verifying and troubleshooting the installation

 on the back. 

Note

: The installation will fail if the SIM card requires a user defined 

APN

 value and you have 

not yet entered this in the EXPLORER 540. Specify the APN value and restart the installation. 
For details, see the EXPLORER 540 User and integrator’s manual.

1.  Attach the base of the pole mount 

bracket to the EXPLORER 540 using the 

included Hex L key on the 4 screws. 

Cau-

tion! 

Max. length of the screws is 9 mm/ 

0.35”! Longer screws can damage the 

EXPLORER 540.

2.  Unscrew two of the long screws from the 

pole mount kit to leave one side open for 
the pole.

3.  Place the pole mount kit with the  

EXPLORER 540 around the pole as shown.

4.  Remount the two remaining long screws. 

Do not tighten the screws completely until 
you have pointed the antenna.

5.  Power up the system. 

Observe the LED between the cable glands 
(see LED description on the back). 

•  LED flashing rapidly green: Starting up
•  LED flashing yellow: Pointing
• 

LED steady yellow: Warning!  
See 

Verifying and troubleshooting 

the installation

 on the back.

6. 

When LED flashes yellow: Turn and tilt the 

EXPLORER 540 and use the pointing sound 
to obtain the highest possible signal 
strength (continuous sound = best signal). 

7.  When you have the highest possible 

signal strength, tighten all the screws on 
the pole mount kit to keep the EXPLORER 
540 in the pointed positionThe EXPLORER 
540 will automatically exit the pointing 
process once it has detected a stable 
BGAN signal.

8.  When the pointing process has ended, the 

LED changes as follows:

•  LED flashing green: 

 

Verifying network connection

• 

LED steady green and then off:  
Ready - installation process has ended 
successfully. The LED is disabled (off) 
after a few minutes.
