TRANSMISSION DISTANCE 

 

The transmission distance achievable with any wireless system is dependent on many 

factors. The only consistent measurement of transmission distance that can be used with 

these devices is called the “line-of-sight” transmission distance. The transmitter and 
receiver are set up in a large open area, free of obstacles and interference, and are aligned 

so their antennas are oriented in the same direction. Under these circumstances, the OM-

CP-RF series products can achieve up to 120 feet (36 m) transmission range. 
 

SYSTEM COMPONENTS AND SETUP 

 

The following components are required to successfully set up and use the OM-CP-RF 

series products: 

 

 

A personal computer running the Windows operating system (Windows 95 or higher) 

 

One of the OM-CP-RF series wireless-enabled data loggers  

 

An RFC101A wireless receiver module and power supply, for receiving wireless 

transmissions from the data logger 

 

An IFC110 interface cable, for communicating with the wireless data logger 

 

Omega Data Recorder software, included with the RFC101A or IFC110 

 
 

To configure the data logger, and register it on the PC for data reception, connect it to 

the PC through the IFC110 serial interface cable as shown in Figure 1 below. 
 

 

Figure 1. Connecting the IFC110 interface cable 

 
 

To set up the system for receiving wireless data, connect the RFC101A to the PC and 

plug in the power supply to a 110VAC outlet (as shown in Figure 2). In most cases, the 

IFC110 will need to be removed from the PC to connect the RFC101A. If there are multiple 
COM ports available on the PC, the RFC101A may be connected to a different COM port than 
the IFC110, thus leaving IFC110 connected. To switch between using the IFC110 and 

RFC101A, simply change to the appropriate COM port under the “Communications” menu.
