OPERATION & MAINTENANCE OF THE MRC-565 PACKET DATA RADIO Rev. F July 23, 2014 Maiden Rock Communications PO Box 575 Seeley Lake, Montana USA Tel: (207) 715 8242 2014 by Maiden Rock Communications All rights reserved Page 2 MRC-565 Packet Data Radio Operations & Maintenance GENERAL WARRANTY Maiden Rock Communications (MRC) warrants that its products conform to the published specifications and are free from manufacturing and material defects for one year after shipment. Warranty-covered equipment that fails during the warranty period will be promptly repaired at MRC’s facility in Kent, Washington. International customers are required to pay shipping costs to the MRC facility, with Seattle as the point of U.S. entry. MRC will pay incoming U.S. duty fees. MRC will pay shipping costs to return the equipment to the customer, with the customer paying all return duty fees. This warranty is contingent upon proper use of the equipment and does not cover equipment that has been modified in any way without MRC’s approval or has been subjected to unusual physical or electrical stress, or on which the original identification marks have been removed or altered. Page 3 MRC-565 Packet Data Radio Operations & Maintenance EXPOSURE TO RF RADIATION The FCC guidelines limit the maximum permitted exposure to RF radiation for Occupational/ Controlled Exposure to 1 mw/sq. cm for frequency ranges of 30-300 MHz. This limit and the following equation for calculating field strength (obtained from OET Bulletin 65) is used to calculate the minimum separation between humans and the transmit antenna based on MPE S= P*G* DC/(4**R*R) P = Transmit power in milliwatts = 100,000 G = Antenna gain referenced to an isotropic radiator = 1.68 (2.2dbi) mobile quarter wave dipole mounted to fender/roof of automobile = 10.0 (10.0 dbi) fixed 5 element Yagi mounted to top of fixed antenna tower = 3.3 (5.2 dbi) fixed half wave dipole mounted to fixed antenna tower leg R = separation required cm DC = Maximum duty cycle of transmitter = 10 % S = Power density = 1 milliwatt/square cm This equation is accurate for the far field of an antenna, but will over-predict power density in the near field. Thus, the near field MPE distances calculated here are “worst case” or conservative. Antenna separation for mobile applications: The typical antenna used in mobile application has a maximum antenna gain of less than 2.2 dBi (¼ wave dipole or ½ wave dipole). To insure safe operation the antenna must be mounted such that the separation between the antenna and any human occupants of the vehicle exceeds .36 meters (14”). The best location for antenna mounting is the center of the vehicle roof. This will provide additional RF shielding between the antenna and the human occupants that reduces the RF exposure to levels well below that specified in FCC OET Bulletin 65. When working on the antenna and or co-ax cable always disable the transmitter by turning its power off. Antenna separation for fixed applications: For fixed applications, antenna gains and mounting techniques can vary depending on the application. For Yagi antennas whose gain does not exceed 10 dBi, that antenna must be mounted a minimum of .90 meters from any humans occupants. Lower gain antennas, such as side mount dipoles, exhibit lower gain (5.2 dBi) allow closer separations (.52 meters for 5.2 dBi antennas). This will provide RF shielding between the antenna and the human occupants that reduce the RF exposure to levels below that specified in FCC OET Bulletin 65. When working on the antenna and or co-ax cable always disable the transmitter by turning its power off.

A summary of these differences is given below:  Number of circuit boards MRC-565 has 2 MCC 545 has 3  MRC-565 is a software defined radio with no adjustments on CMU board  Both units have similar power amp boards  No battery backed up RAM. No PWR FAIL RESTORE message  New LPM modes  Ethernet Port with TCP/IP  USB Host Port for Thumb drive Logging and Data Storage  USB Device Port for connecting to PC USB port. Requires Driver For the most part the MRC-565 operator commands are the same as the MCC 545B commands. However, there are a few differences as noted below: MCC 565 MRC 545 ASSIGN ASSIGN ASSIGN,RXn,CHAN,PROTOCOL NONE CHAN,TX,RX,MOD-VAL,CHAN FREQ,TX,RX,CHAN CHAN,N FREQ,N CHAN FREQ CAL NONE DSP NONE IP NONE IPCONFIG NONE FILE NONE FPGA FPGA LPM LP[M RECEIVERS NONE SCALE SCALE SP NONE SIG NONE RXTH RXTH TEST,TX TEST,TX TRACEERT TRACEPORT SDI12 NONE In the cases where there are similar commands for the MCC 545 and MRC-565, the commands are slightly different.
