STA-16 STATUS INPUT INTERFACE
STA-16 Photo and Ordering Information
The STA-16 Status Input Interface provides two 8 channel status input ports which allow input of on/off status information into a conventional PC for a wide variety of monitoring and signaling applications. Uses include the input of on/off status information of relays, switches, thermostats, security system motion detectors and magnetic switches, smoke detectors, heating and air conditioning equipment, air flow switches, air damper position switches, pressure switches and thousands of other devices. The STA-16 also has many applications in HVAC and home automation. The energy consumption of equipment with a constant load (lighting, resistance heating, hot water heaters, etc.) is easily computed by multiplying the time on by the equipment's KW rating. The STA-16 is ideal for use in logging energy usage or equipment performance and is also well suited for use as a security system logger (to record times doors are opened, motion detectors tripped, alarms or other events). Other uses include the input of 8 or 16 bit binary codes for interfacing to TTL or CMOS level digital signals (allowing connection to counters, parallel data bus lines and other types of digital devices and equipment). The KY-12M Keypad may be connected directly to the STA-16 status input ports for use with security systems, door entry access, remote data entry and other uses. A modem will permit the status inputs to be monitored from a remote site (or use an Internet connection). The status information is obtained by transmitting a single byte port code to the STA-16. The STA-16 then transmits back a single byte code with each bit representing the 8 inputs on that port. The status inputs are turned on by applying a small current (6 ma typical) to the LED inside the opto coupler on the STA-16 (minimum 1.5 volts required, common cathode). Optional AC opto couplers are available which will turn on in both directions, allowing for both common cathode and common anode configurations. The input voltage range defaults to a 6 to 18 volt range with a 1.8 K series resistor to the LED (the STA-16 may be ordered with other resistor values or with no resistors by specifying the /M option). The STA-16 Status Input Interface provides a relay expansion port to control up to 112 relays (using EX-16 or EX-32 relay expansion cards
) and an input expansion port which allows for expansion to 144 status inputs or 32 analog inputs (using ST-32
or AD-32 expansion cards). An optional Touch Tone input is also available. Includes technical reference, software examples and STA-16 Data Acquisition Software for Windows (for use with Windows versions 3.0, 3.1, Windows 95, 98, 2000, ME, NT, XP, Vista and Windows 7, 8). Software is also provided that allow the STA-16 inputs and/or relays to be controlled or monitored over a network (LAN, Internet, etc.).

VC-1 Photo and Ordering Information
The STA-16 may be ordered with an optional touch tone input which decodes all 12 of the standard telephone tones plus 4 additional tones which may be used for control functions. An interrupt output is provided on the STA-16 which may be used in generating an RS-232 interrupt when a tone is detected. A Molex connector (.1" centers) is used for connection to the touch tone input. The touch tone input may be connected directly to a telephone line with the addition of the VC-1 voice coupler. The touch tone input may be used for a variety of applications such as voice mail, telephone call routing, and remote control applications which allow remote input of control functions into a conventional PC from any touch tone telephone.
VC-1 VOICE COUPLER...
The VC-1 connects directly to the STA-16 tone input via a Molex connector cable (included). A terminal block is provided for connection to a power source and for the RS-232 I/O interface connection to your PC. This interface allows the PC to monitor for rings and allows the PC to place the telephone off-hook. The VC-1 may share the same RS-232 that is used with the STA-16. Two RJ11 telephone jacks are provided on the VC-1 which are selectable line 1 or line 2. One of the RJ11 jacks is used for connection to the telephone line and the other RJ11 may be used for connection to an additional telephone, modem or other device. The VC-1 also provides voice input and voice output connections which may be used with a sound card. The voice input may be used for providing a message to the calling party, music on hold or other functions. The voice output may be used to record a message from the calling party or for other uses. LED indicator lamps are provided to indicate ring, off-hook and power. Requires a power source (12 to 14 volts DC, 100ma). Dimensions are 2.25" by 4".
The KY-12M keypad is a 12 key keypad with a matrix decoder. The keypad connects to the decoder card via an 18" ribbon cable (provided) and the decoder card connects to the STA-16, ADC-16, ST-32 or AD-16 port via a 14" ribbon cable (provided). The KY-12M requires 4 digital or analog inputs. An interrupt output is provided on the KY-12M which may be used in generating an RS-232 interrupt when a key press is detected. The KY-12M may be ordered with a terminal block in place of the ribbon cable for installation away from the STA-16 or for use with other types of equipment which provide TTL level digital inputs. The KY-12M Keypad may be powered through the ribbon cable by the STA-16 or ADC-16 or may be powered by an external 5 to 12 volt DC power source (50 ma).
