assembled. To install the PC Card and use the ECB, some

disassembly and reassembly is required.

2 Remove the cap from the ECB by pulling on the side of the cap to

release it as shown in the following ﬁgure. When you remove the

cap, you will see the PC Card slot.

3 If you are planning to mount the ECB on the wall or ceiling

(optional), remove the bottom mounting plate as shown in the

following ﬁgure.

NOTE:

4 Remove the small combs from the end cap. The combs are

generally not needed, but when cut to an appropriate size they

prevent the PC Card from vibrating out of the socket when the

ECB is in an environment with extreme vibrations.

5 Gently insert the PC Card (face up) into the slot as shown in the

following ﬁgure.

6 Replace the cap, which you removed in step 2, by snapping the

cap straight down on the body.

mounting plate, which you removed previously, where desired. After

the mounting plate is installed, place the ECB onto the mounting

plate and snap it into place. Ensure that the ECB is secure.

8 Connect a standard straight-through 10BASE-T Ethernet cable

between the RJ-45 port (ECB ports and connectors are shown

you will install the ECB Conﬁguration Utility software.

9 Connect the six-pin DC power cable to the power adapter.

10 Connect the AC power cord to the other side of the power adapter.

11 Connect the round power plug to the ECB power jack labeled 5 VDC.
