1. Production Applications
The OEM wireless modem is well suited for mobile and fixed applications. The wireless modem enables
user to send/receive data anytime anywhere, and can provide communications for a wide variety of
products.
1.1 Portable Terminal Use
Portable designs produce good environment for an integrated modem. The portable terminal is
typically battery powered, subject to temperature extremes, and designed to be physically
strong. When designing portable device, user needs to pay attention to the following issue:
-
DC power noise levels on the host interface
-
Minimum operating voltage levels
-
Device internal ambient temperature
-
Antenna gain and proximity to user
-
Mechanical design for drop, vibration, dust, salt and liquid spill.
Note : Regarding this last point, CNI-800D modem is designed on the assumption that the host device
will control these conditions.
1.2 Fixed Mount Usage
Fixed-mount usage eliminates most of the mechanical constraints of handheld designs. The
core requirement applies, but fixed usage does not present any special conditions to address.

Installation
Installing CNI-800D modem is very simple as follows:
1. Place the modem to connector on product housing, and apply a little force to push it down to be
connected.
Caution : Care not to bend or damage the connector pins.
2. Use four #2-56 UNC 2A machine screws to tie up the modem as the figure shown below.
3. Connect modem connection cable to a small hole provided at the rear of the modem.
4. Connect the modem connection cable to Antenna

Mounting
Proper mounting of the modem requires a combination of securely fastening it within the product housing
as well as adequately grounding the modem case to the housing.
1.1
Fastening
Mount the modem to the rigid OEM product housing by using four #2-56 UNC 2A
machine screws as the figure shown below:
