When it is turned on, it receives and it may transmit radio frequency energy in the 900MHz band. During transmission, the output power level at the antenna port varies over a range from 0.125 to 1 watt. The paging carrier service provider controls the output power level. 12/2/02 User's Guide for the PerComm OMNIDATA Telemetry Device - PT1005A (DRAFT) 2
Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002 The antenna used for this transmitter must be fixed mounted in a permanent structure providing a separation distance of at least 20 cm from all persons during normal operation. The OMNIDATA is provided without an external antenna. PerComm used the Larsen quarter-wave dipole antenna model SPWH20918 with a 4-inchx4-inch metallic ground plane during measurements for FCC certification. If another antenna is used its maximum gain should not exceed the theoretical dipole gain of 2.15dBi. The maximum radiated output power of the antenna satisfies the maximum permissible exposure (MPE) limits as specified in §1.1310 of FCC regulations for general population/uncontrolled exposure as long as the minimum separation distance of 20cm between the radiating element and the person is maintained and the maximum gain is less than 2.15dBi. 1.7 References Refer to Table 1 for a list of referenced documents.

Drill a 0.25 inch diameter hole in the mounting surface and the ground 12/2/02 User's Guide for the PerComm OMNIDATA Telemetry Device - PT1005A (DRAFT) 11
Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002 plane. d. Insert the SMA female bulkhead end of the PE cable through the hole from below. e. Secure the PE cable to the mounting surface and the ground plane with a lockwasher and nut (supplied with the cable). Tighten the nut firmly enough to solidly fix the connector, but take care not to overtighten. f. Screw the Larsen antenna to the SMA female end of the cable just installed. Firmly finger tighten. Do not attempt to use any tools to tighten 2. Install the OMNIDATA Device a. The OMNIDATA device consists of a single printed circuit board assembly. b. Install the OMNIDATA device using appropriate standoffs (e.g. Richco part number LMSP-4-01). c. Ensure that sufficient space is available to connect the antenna cabling, host cabling and power supply cabling. Mechanical drawings of the OMNIDATA device are shown in Section 3.5 to assist in this process. d. Attach the SMA male end of the cable installed in step 1 above, to the SMA female connector on the OMNIDATA device. Tighten the SMA connector to 8-10 inch-pounds of torque. Over tightening can damage the connector and reduce the performance of the OMNIDATA device. 3. Install the Host and Power Supply a. Install the host and power supply. The host must conform to the following guidelines: i. The host supports the pin out specified in Table 5. ii. The power supply must conform to the specifications identified in Section 2.9. iii. The host implements a supported host interface protocol (HCI [2] or CLP [3].) Contact your service provider to determine which protocol is enabled on your OMNIDATA device. b. Connect the host and power supply to the OMNIDATA device’s host interface header. 4. Turn on the Power Supply a. Follow the instructions in Section 4.4. 4.4 Power-On Procedure After power has been applied, follow the instructions listed here to verify operation of the OMNIDATA device. Please refer to the appropriate host interface protocol document (HCI [2] or CLP [3]) to determine how to execute these instructions. 12/2/02 User's Guide for the PerComm OMNIDATA Telemetry Device - PT1005A (DRAFT) 12
Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002 1. Query the OMNIDATA device with the host. Verify that the host is able to communicate with the OMNIDATA device. 2. Periodically poll the OMNIDATA device until the device has registered on the ReFLEX network for full two-way service. 3. Use the host and OMNIDATA device to send a message to the PIN or email address associated with the OMNIDATA device being used. Verify that the message is successfully accepted by the ReFLEX network. Verify that the message is successfully received by the OMNIDATA device. 4.5 External Antenna Impedance The OMNIDATA transmitter was designed for a 50 ohms external antenna. The same antenna is used for transmit and receive, hence the antenna has to work from 901MHz to 941MHz. It is possible to connect the external antenna directly to the device or through a coaxial cable. The external antenna should be mounted close enough to the OMNIDATA unit to limit the length of the cable and the losses in it. The external antenna assembly must have a standard male SMA connector. If the load presented by the external antenna assembly at the SMA port is not 50 ohms, the output power of the transmitter and the DC current consumption during transmit time may vary from theirs nominal values. The VSWR of the external antenna assembly in the transmit band 901 to 902 MHz should be less than 1.7. If the VSWR is greater than 1.7 the transmitter might be permanently damaged. The solution is to have the antenna re-matched or to impose restrictions on the length of the cable between the external antenna and the unit. Please contact PerComm for further details. 12/2/02 User's Guide for the PerComm OMNIDATA Telemetry Device - PT1005A (DRAFT) 13
