![]() To do this, it is necessary to agree in advance the time of departure, and provide information on the name, number of radios at the facility, organize programmer access to the facility and collect (provide) radios for programming. If the walkie-talkies are already at the facility, and the removal of the walkie-talkies from use is not possible, then the programmers of our company can go to the site to program the walkie-talkies. Also, programming of radios is necessary when docking a new fleet of radios with an old one. The need for radio programming (introducing frequency ratings into the memory of fixed radio channels) arises both when buying new radios, and when interference occurs on already used frequencies. Several frequencies recorded in the memory improve communication capabilities, allow you to get away from sudden interference, and organize groups of subscribers. This does not make it comfortable to use walkie-talkies. Walkie-talkies cannot be used without frequencies programmed into memory, and test frequencies often do not have subtone frequencies that reduce channel interference. Most walkie-talkie manufacturers supply new products either with an empty frequency bank or with a test frequency recorded in the first channel. If you're using a so-called RIB-less programming cable instead of a RIB and the standard DB25-to-RJ45 modular programming cable, you still should be able to access the other end of the cable and add the resistor to the appropriate wires.OUR COMPANY CARRIES OUT: programming of walkie-talkies, docking of walkie-talkies by frequency, recording frequencies in the memory of walkie-talkies. To prevent burning anything out, I recommend that you use a 100 ohm 1/4 watt resistor instead of plain wire for the jumper between the modular plug pin 8 and pin 6. This is because the MaraTrac has full battery voltage (13-14V) on that pin (they number it pin 1) at basically unlimited current (well, until something burns up) and the Hook input on the logic board has a 10V Zener diode protecting it, unlike the PTT input which has a 27V Zener diode protecting it. However, you WILL have a problem if you use this modified cable on a MaraTrac. Cautions With Other Radios: MaxTrac, Radius, GM300, DeskTrac, SM50, SM120, M1225, R1225, CDM, and GTX radios either don't use pins 7 and 8 (what some of them refer to as pins 1 and 2), or supply only 5-8V or have a 27V Zener diode on the Hook line, so the added jumper will have no effect. ![]()
