Summary of Function and Use The OS2400s are radios which have been designed to provide a wireless connection between any two devices which could otherwise be physically cabled together. Spread spectrum: These radios transmit using a technique known as "spread spectrum, frequency hopping communications". Using the spread spectrum technique a narrow band signal is spread over a broader portion of the radio frequency band.

FCC Compliance Statement FCC RULES The statements contained in this section "FCC RULES" are requir ed. If the Locus Inc. OverAir Solutions OS2400 radio is used as a component of any device, these statements must be a component of that device’s product documentation. FCC COMPLIANCE STATEMENT The Locus Inc. Overair Solutions OS2400 device complies with Part 15 of the FCC Rules.
PAGE 7
Gain / User Proximity to Antenna It is important to keep the radio’s antenna a safe distance from the user. In order to meet the requirements of FCC part 2.1091 for radio frequency radiation exposure, this module must be used in such a way as to guarantee at least 20 cm between the antenna and the body. The FCC requires a minimum distance from the user of "Distance for 1mW cm2 squared powe r density" or 20cm, which ever is the greater distance.
PAGE 8
Max Antenna Gain / Output Power NOTE: All of the Locus Inc. ap proved antennas meet this Point -to-Point antenna gain / output power emissions requirement. For a list of the antennas approved by Locus, Inc. for use with its OverAir Solutions OS2400 module, see See “MANUFACTURER -APPROVED ANTENNAS”on page 14. The FCC transmitter power limit for this type of radio is 30 dBm (or 1 watt). In addition, to ensure safety, the output of this module is limited to 250mW.

Setup Overview A new radio network must be configured to function as required for the specific application.
PAGE 11
The Setup / Diagnostic Software The OS2400 Setup Application provides a user interface for the configuration and maintenance of a radio network, regardless of the intended application. It graphically reflects the physical layout of the component radios. The Setup Application provides a means to: ? ? configure new networks or radios: ? ? assign roles (Master or Remote) to the radios. ? ? define data paths ? ? set the radio’s operation parameters (baud rate, parity, et c.

CABLE SPECIFICATIONS The Radio is considered to be a DCE device and the PC a DTE device. The following illustrates the wiring of the straight through serial cable which is connected to the: ? ? the Configuring PC and each radio that as it is configured ? ? the Configuring PC and the Master radio.

THE SERIAL PORT 15
PAGE 16
VIEWING THE SERIAL PORT SETTINGS The serial port of the Configuration PC must be identified and its parameters set before radio communication can begin. To view the current settings, from the main menu of the OS2400 Setup Application select: ? ? SERIAL PORT ? ? CONFIGURE The displayed dialog box has three tabs. With the first of the tabbed dialog boxes, PORT, the serial port settings are displayed. To understand how to customize these settings see Setting the Serial Port.
PAGE 17
SETTING THE SERIAL PORT These are the factory set serial port parameters for the Configuration PC. Change these defaults with care. ? ? Baud rate: 115200 (default). ? ? Parity: None (default). ? ? Data Bits: 8 (default). ? ? Stop Bits: 1 (default). ? ? Handshaking: It is suggested that the handshaking defaults not be changed. ? ? Xon/Xoff OFF ? ? Rts/Cts ON (Request to Send/Clear to Send) ? ? Dtr/Dsr OFF (Data Terminal Ready/Data Set Ready) ? ? From the drop down list, select the COM port to be used.

RADIO NETWORK DEFINED A radio network provides a wireless communication link between a Master Device and any Remote Device that could be connected to Master Device using a serial cable. For example, a Master Device and its associated Remote Device can be: ? ? a computer with a printer, ? ? a computer with a scanner, ? ? a scanner with a printer.

POINT-TO-POINT There are two network types , point-to-point and point-to-multipoint. In all networks there is only one Master Radio. Point–to–Point networks are the simplest radio network consisting of one Master Radio and one Remote Radio, one Master Device that must communicate with a Remote Device. Several point-to-point networks can operate at the same location, however each Master-Remote network must use a different communication channel.
PAGE 26
POINT-MULTIPOINT In Point-Multipoint networks one Master Radio is in communication with at l east two Remote Radios. The Remotes can only communicate with their Master. Remotes cannot communicate with each other directly, the data must be passed through the Master. A Point-Multipoint network will not work with an applicat ion which requires peer to peer communication. The OS2400 Point -Multipoint network can only be used with applications that use the Modbus communication protocol.
