User Manual Cervis Inc. Safety Precautions Read and follow all instructions. Failure to abide by Safety Precautions may result in equipment failure, loss of authority to operate the equipment, and personal injury. Use and maintain proper wiring. Follow equipment manufacturer instructions. Improper, loose, and frayed wiring can cause system failure, equipment damage, and intermittent operation.
Module SRF310 1.0 SRF310 Introduction The SRF310 receive/transmit module (RTM) is based on a single-chip radio frequency (RF) transceiver integrated circuit (RFIC), an Atmel AT86RF212B. The SRF310 RTM is intended to be integrated into Cervis Inc. products, providing a wireless RF connectivity option. The SRF310 RTM operates in the 915 MHz ISM band, using spread spectrum modulation with a maximum conducted RF transmit power of +22.07dBm (161mW) at the antenna port.

User Manual 2.0 SRF310 Installation When integrating an SRF310 RTM into a host application, the user must provide all text in the “FCC Statements” and “Industry Canada Statements” in the host application’s user manual (see Forward Material). The text must not be modified in any way and presented in a conspicuous manner that the end user can be reasonably expected to access.
Module SRF310 Figure 4. SRF310 installed in a typical host application. 3.0 SRF310 Tune-up Procedure There is no tune-up procedure. The module contains no adjustable components. Proper RF operation of the module is verified during the manufacturing process using suitable equipment and methods. Limitation of conducted peak RF power and duty cycle is controlled by proprietary firmware that may not be modified by an end user. 4.0 SRF310 Electrical Characteristics 4.
User Manual 4.2 Operating Current The SRF310 RTM has four primary operating conditions that draw differing amounts of current from to 3.0-3.3V power source: Off PLL_ON RX TX RFIC is powered down, minimal load RFIC is ready to transmit or receive, ~5mA RFIC is receiving a message, ~25mA RFIC is transmitting, ~25-100mA, depending on TX output power In TX mode the operating current may be less than the maximum if the drive to the external PA is reduced because the full RF output power is not required. 4.
Module SRF310 The required separation distances are measured from the actual location of the radiated part of the antenna. An antenna may be inside the host application, affixed to the enclosure of the host application or at the end of an optional extension coaxial cable. Mobile applications: Equipment must be mounted in a location at least 20cm away from areas likely to be occupied by an unaware person.
