Sine System 8 channel remote control system complete with RAK-1 assembly The components in this very complete system are : RFC-1 Sine ‘brain’ RAK-1 Intelligent rack adapter which includes nesting and connections for the RFC-1 as well as modem circuitry, printer interface output, surge suppression and UPS battery back-up RP-8 Control interface panel for 8 channels of analog metering inputs, 16 momentary 1-C relay contacts (8 ‘raise’ and 8 ‘lower’) SP-8 Surge protection for 8 channel metering channels as well as the phone line This system was bought new for an analog LPTV site that has since been shut down liberating this equipment for resale. Located in a totally air-conditioned building this system is in pristine condition. Although all channels were used for both metering and control, all relay command operations were logic level and no relay contact was ever exposed to more than 125 mas at 24 volts. These very flexible Sine System controllers are the workhorses of the broadcast industry and also find exceptional acceptance in process industries where telephone control and interrogation of equipment status is desirable. Each RFC-1 brain can handle up to 64 channels of telemetry and 128 relay commands when the maximum number of eight RP-8 interface panels are attached. The user can program each metering channel with a logic or a magnitude for the readout as well as the numeric value or state. E.G. for the former condition ‘ 242.7 volts’ and for the latter condition something like status ‘auxiliary ‘ or ' On '. The brain can be programmed to continuously monitor up to 8 channels and take action based on metering changes such as a voltage value too high or too long. Eight ‘action sequence’ programs can be constructed to automatically take complex action such as turn on and change to an auxiliary transmitter when the main fails. These sequences can be automatically or manually initiated. These action sequences can be used as well to automatically alert organization personnel via either pager or phone calls. Information over the phone connection is done by computer voice, by pager in alpha-numeric format and by modem via ASCII messaging. The brain also has its own clock for commanding operations based on time of day and/or day of week and/or month. The RAK-1 contains batteries for UPS operation that provide hours of self-powered operation when the batteries are new. The RAK-1 also charges these back-up gel cell batteries. 120 volt AC power is inputted via an IEC connector on the back of the RAK-1. Power cord can be provided upon request. Note : This RAK-1 has all new UPS batteries (three) bought for the sale. The extraneous relay on the RP-8 panel visible in the pictures had been used as a logic level changer and can be left or removed per purchaser’s desire. Please review pictures carefully. From the Sine Systems literature … Data Communications The RAK-1 contains a 2400 baud telephone AT command set modem. The modem allows the RFC-1/B to be polled for telemetry data and controlled by an external computer at a remote site. The RFC-1/B can also log telemetry data and place alarm calls through the modem. The modem uses the same telephone line that is used for voice/DTMF operation so new lines are not necessary. The RFC-1/B firmware has the necessary intelligence to place outgoing data calls to log data without assistance from an external computer. Parallel Printer Port The parallel printer port allows an inexpensive parallel printer to be attached to the RAK/RFC system so that telemetry readings and/or system alarms can be logged to a local printer. Flexible programming in the RFC-1/B allows you to program how often readings will print. The printer must be a true parallel printer and not a Windows printer that uses a parallel interface. Windows printers lack some of the necessary intelligence to handle simple printing tasks. (Printer that had been used with this system is available for purchase separately for $ 49.oo if desired.) Surge Suppression Surprisingly, the vast majority of damage from lighting on remote control systems comes, not through telemetry sources or power supply, but from the telephone network. The RAK-1 uses a system of heavy duty gas surge arrestors, metal oxide varistors and polyswitch type fuses to suppress damaging electrical spikes before they can harm the system. The system should still be protected from spikes that may pass through telemetry sources. For that we recommend the SP-8/TO Heavy Duty Surge Protector–an inexpensive device that attaches to the relay panel and protects the eight telemetry inputs from damaging spikes. Overall an outstanding, flexible and well thought phone based remote control system for broadcast or the process industry.

Any errors in fine program details we can correct remotely over the phone once connected to this Sine. Any additional Sine material required such as additional RP-8s and temperature sensors etc. are available from Armstrong Transmitter the owner of Sine Systems. 4835 North Street Marcellus, NY 13108 phone: 315.673.1269 fax: 315.673.9972 email: info@armstrongtx.com
