Page 2-14 Vector-LP Radio Beacon Transmitter Technical Instruction ManualIssue 1.1 Section 2 Preparation for Use and Installation2.3.4 Cabinet MountingIf the user is supplying the 19-inchmounting cabinet, install the transmitter inthe cabinet, ensuring the drawer slides oneach side of the transmitter are mated/locked together.If the deluxe cabinet,short cabinet or IP66 cabinet option waspurchased, the transmitter is shipped fromNautel inside the cabinet.If the transmitter was shipped in a deluxecabinet or short cabinet, temporarilyremove both of the cabinet’s side panels(two screws at the top of the cabinet and,for the short cabinet, two additionalscrews on the lower, front and rear) andthen remove four shipping screws (M8,two on each side) from the transmitter(see Figure MD-1B or MD-1D).2.3.5 Determining Control/Monitoring RequirementsThere are several remote control andmonitoring options to consider beforeinstalling external wiring. The pre-installation information in paragraph 2.2identifies the remote controls and alarm/status outputs available. It is assumed theuser has already reviewed this informationand has determined which to use. It isalso assumed the options available for thecontrol inputs and the monitoring outputshave been reviewed and the user hasdetermined which options are required tointerface with the external equipment.2.3.6 Installing External Control/Monitor WiringConnect the wiring from the remotecontrol/monitoring devices to the remoteinterface PWB (A3) as follows:NOTERemote control and monitor wiringterminate on the remote interface PWB(A3), which is accessible from the back ofthe front panel (see Figure 2-2). Theconnectors, included in the ancillary kit,are solder-cup type and the terminalblocks accept wires sizes (AWG) # 14through # 24.A cable routing channel (see Figure 2-2)allows wiring to pass between the frontand back of the transmitter. Remotecontrol/monitor wiring should enter andexit at the back of the transmitter.Table 2-3: ATU Serial Interface(for INTERNAL RS-485 connector J3)Description Pin+5V (ISOL) 1GND (ISOL) 2, 6, 25INT BUS (+) 3INT BUS (-) 4DE/RE 5Table 2-4: RS-422 Remote Interface(for RS-422 connector J4)Description PinTX 1TX 2GND 5RX 7RX 8Table 2-5: RS-232 Remote Interface(for RS-232 connector J5)Description PinDCD 1RXD 2TXD 3DTR 4GND 5DSR 6RTS 7CTS 8(a) Route wires from the back of thetransmitter through the cable routingchannel hole to the remote interfacePWB (A3) on the back of the frontpanel. Using Tables 2-3 through 2-5(note the applicable serial interfaceoptions), determine the specificdestination of each wire.(b) Pass all control/monitor wires,including their shields, through aferrite toroid supplied in the ancillarykit. If practical, pass the wires througheach toroid a minimum of two times(two turns).
