Mounting methods
RIM OEM Radio Modem for GSM/GPRS Wireless Networks can be securely fastened using a variety
of methods; however, you must consider the operating environment when you choose a mounting
option. For example, extreme temperature, heavy vibration, or areas with high electromagnetic
interference can require a special mounting solution. You must make sure that the radio modem
remains securely attached in the environment in which it is used.
This section describes the following mounting methods:
• bolts or standoffs
• tie wraps
• permanent industrial adhesive
The following information is presented as a guide; however, applications can vary considerably. A
mechanical engineer can help you make sure that the mounting method that you choose is suitable
for your application.
Bolts or standoffs
The radio modem includes a hole in each corner, which can be used to bolt the device onto a circuit
board, device housing, standoffs, or other surface. The mounting hole pattern is four holes in a 62.5-
by-36.5 mm rectangle, with each hole 2.5 mm in diameter.
To allow room under the radio for components on your board, you can use standoffs instead of
bolts, as illustrated in the following diagram.
