Configurations of JOTRON Series 7000 VHF Radios

The 7000 series VHF/AM radio system includes separate Receiver (RX) and Transmitter (TX) modules (Fig. 1). Each module has facilities for being connected to other modules as a part of a main/standby chain, and as a transceiver configuration.

Fig. 1 The radio units have a built-in coaxial relay for antenna switching, an Alarm output and a Select input for automatic and/or manual main/standby selection. In addition the transmitters have a Key/Mute output used to mute associated receivers during transmitting periods. The antenna is connected to the transmitters antenna output and routed via a built-in coaxial relay to the transmitters antenna output. From there a coaxial cable connect the antenna to the receivers antenna input. When the transmitter is not keyed the coaxial relay will switch the antenna to the TX antenna output and from there to the connected receiver. When a key signal is applied to the transmitter the coaxial relay will switch the antenna to the transmitter output. The same key signal is used to mute the receiver during transmission. The audio line is connected in parallel to the transmitter and receiver.

Single Radio Setup General:

The radio modules can be controlled directly from the front panel, and via a range of remote equipment and accessories. Remote Audio and PTT Only:

The Operator at the remote site(s) is able to monitor traffic, and to communicate on the current frequency of the local transceiver, through the Audio Remote Control unit (ARC). A red LED indicator on the ARC will alert the operator if there is an alarm on the local radio unit. (Fig. 2).

It is possible to connect more than one ARC to the same radio. The number of wires can be reduced to two wires, but in this case the ARC will loose functionality (the sq, alarm indicator will not be available) Remote Site Local Site

Paralell The maximum distance between ARC and radio unit is approximately 2 km, provided a high quality screened cable is used. To connect a pair of radio units as main/standby, the alarm output from main unit is connected to the select input of the standby unit. Also, the initial main unit must be told that it is the main unit by accessing its configuration programme and set its operation to Main. The standby radio unit is automatically selected if there is an alarm on the main unit. The switch is a built-in coaxial relay. Selection can also be done manually from the ARC. (Fig. 3).

Long Range Audio and PTT: Communication via leased lines is made possible by use of the Audio/PTT modem (APM). (Fig. 4). One APM unit is able to access two transceivers (ie. Main + Standby unit). In the below ex.with the APM modem, the APM uses inband & FSK signalling and demands uncompressed audio line.

The Audio/PTT modem uses in-band tones for transfer of Squelch and PTT. Alarm (Main and Standby unit) and Main/Standby selection uses FSK data. The 2 or 4 wires must be ordered specific as this is not standard. Limited Remote Access to Radio Control: Adding an Operators Remote Control unit (ORC) to the set-up shown in Fig. 3, enables the operator to toggle between the frequencies, which have been programmed into the radios. (Fig. 5) With the use of this configuration it is recommended to use an ADAM-4510/4510S repeater . This unit simply amplifies, or boosts, existing RS-422/485 signals to enable them to covers longer distances. It extends the communication distance by 4000 ft (1200 m) or increases the maximum number of connected nodes by 32. In addition the 4510S version provides galvanic isolation between input and output so that any difference in GND potential between each end of the RS485 line will be compensated for. By the below example you may choose if you would like common audio – or separate Rx/Tx audio. Remote Site Local Site

Full Remote Access to Radio Control: Adding a Digital Remote Control unit (DRC) to the set-up shown in Fig. 3, gives the operator access to all operating paramenters of the radios. (Fig. 6). This ex. is for distances less than 2 km from radio – remote sites. For distances over 2 km, the Audio & PTT modem is required. Remote Site Local Site Ant.RS-485/ adam repeater Main unit ARC DRC

Long Range Remote Access through PC and RACS programme: By adding a RACS Control unit (RCU) to the radios at the local site and a set of modems, the radios can be monitored and accessed remotely from a PC. The PC must have RACS (Remote Access and Control System) licenced programme installed. (Fig. 8). The RACS Control Unit can give access to up to 64 radio units. No information is stored in the computer. Every required information is retrived from the radio units when connecting to the site via the RCU unit. This means that new units can be installed and immediately accessed from the central computer. It is possible to use the RACS programme to access as many sites as needed. Audio and PTT is either assumed to be controlled by a VCCS, or by the APM, which gives access to one pair of radio units (Main/Stby Transceiver). Additional APM and ARC units must be added as number of radio units increases. Alternatively, a Com260 and TE10-39 controller panels can be used (Ref. Fig. 9). Remote Site Local Site

Multiple Radio Setup Small Airport: The example shows a small airport with 3 operators, of which one is a supervisor. The airport has 3 operating frequencies. Each frequency is configured with Main and Standby transceiver. The radios are located in the equipment room and remotely operated from the tower. Each operator has one TE10-39 terminal with access to all three radio frequencies, and to each other via intercom. Supervisor has full access to all parameters of all radios via PC with RACS.

Filters Applications requiring filter:

• Transmitting and receiving more than one frequency through the same antenna. • Antennas are located close together. Use filters to attenuate unwanted frequencies.

Antenna sharing: Use Transmitter Cavity Combiners when several transmitters are using the same antenna. Use Receiver combiners when several receivers are using the same antenna. It is also recommended to use a Multicoupler to connect several receivers to the same antenna. JOTRON Electronics a.s. supply different types of filters, multicouplers, combiners and splitters for both the VHF and the UHF equipment. We tailor a system to your needs which will fully comply to your critical co-location and frequency allocations. Please contact the sales department for further information and prices.
