98 Series FSK Tone Telemetry

The INIVEN 98 Series FSK Telemetry equipment communicates analog, contact closures, and digital data information over analog tone lines or point to point fiber optics. All modules are microprocessor controlled, and frequency shift keyed (FSK) modules utilize digital signal processing (DSP) for frequency stability.

The 98 Series has a modular design, allowing for a variety of analog and digital applications. Each communication and multiplexing module can accept different I/O modules in the same chassis slot. These I/O modules accept different forms of analog and digital inputs and outputs, and provide terminal blocks for external wiring.

The 98 Series offers several different enclosures: A standard 19" rack mount chassis, a variable width panel mount chassis and a compact chassis. All programming is accomplished using DIP switches, eliminating the need for an external programming device. Each FSK module is programmable for all standard Bell frequencies. System configuration options, such as 2 frequency or 3 frequency operation are also programmable.

The 98 Series is sub-station hardened. It is end to end compatible with most telemetry systems and is pin to pin compatible with other manufacturers. As with all INIVEN products, the 98 Series is protected by a 12 Year Warranty.

IT-98DSP PROGRAMMABLE FSK TRANSMITTER

The IT-98 DSP FSK Transmitter generates one of three tone frequencies for use on an audio communications circuit or with a digital converter, a fiber optic or serial interface. Depending on the type of I/O module connected to the IT-98SDP, the unit can be triggered by either digital on/off or analog inputs. The FSK transmitter can also be used to convert an Iniven multiplexer transmitter's output to an audio signal.

IR-98DSP PROGRAMMABLE FSK RECEIVER

The IR-98DSP FSK Receiver can accept one of three tone frequencies from an audio communications circuit or with a digital converter, a fiber optic or serial interface. Depending on the type of I/O module connected to the IR-98SDP, the unit can output either digital on/off or analog data. The FSK receiver can also convert an audio signal to a digital output used by an Iniven multiplexer receiver.

IMT-98 PROGRAMMABLE MULTIPLEXER TRANSMITTER

The IMT-98 is a programmable analog to digital transmitter capable of sending up to 8 analog and 16 digital (on/off) functions. The IMT-98 generates a digital output that can be transmitted over a fiber optic circuit or input to a single IT-98DSP FSK module and sent over an audio circuit.

IMR-98 PROGRAMMABLE MULTIPLEXER RECEIVER

The IMR-98 is a programmable digital to analog receiver capable of accepting up to 8 analog and 16 digital (on/off) functions. The IMR-98 receives a digital input from a fiber optic circuit or output from a single IR-98DSP FSK module receiving a signal from an audio circuit.

IM-RELAY MULTIPLEXER RELAY MODULE

The IM-RELAY contains 8 form C relays used as dry contact outputs for the IMR-98's status outputs. The IM-RELAY interfaces with the multiplexer receiver using a ribbon cable. The ribbon simplifies wiring by snapping into the I/O RELAY (IM-RELAY I/O module) at one end and the I/O RIBBON (IMR-98 ribbon connector I/O module) at the other. To accommodate all 16 dry contact outputs, 2 IM-RELAY's are required.

I/O 40T AND I/O 40R SINGLE ANALOG I/O MODULES

The I/O 40T (transmitter) and I/O 40R (receiver)are input/output modules that allow the IT-98DSPand IR-98DSP to convert an analog input to an audio signal and reverse the process without changing the FSK module. Various inputs and outputs can be accommodated including bi-polar voltage or current.

I/O DATA STANDARD FSK I/O MODULE

The I/O DATA is the standard I/O module for the IT-98DSP and IR-98DSP FSK modules. This module contains the wiring terminal blocks and circuits required to pass the inputs and outputs to the FSK module.

I/O RS232 MODULE

The I/O RS232 Module can be used two different ways. When connected to an FSK module, the I/O RS232 is used to key the transmitter or is keyed by the receiver. When used with a 98 multiplexer, the I/O RS232 converts the digital inputs and outputs to a RS-232 communication format. The I/O RS232 may be interfaced directly to an FSK module or indirectly (wired inputs/outputs without a module being mated via connector) with an analog or multiplexer application. Both DCE and DTE versions of the I/O RS232 module are available.

I/O STD STANDARD MULTIPLEXER I/O MODULE

The I/O STD is the standard I/O for the IMT-98 and IMR-98. This module contains the wiring terminal blocks and circuits required to pass the 16 digital and 8 analog inputs and outputs to the multiplexer module. The I/O STD is also used when interfacing a multiplexer to an RS-232 or fiber optic circuit (the I/O RS232 or I/O FO are also required.

I/O RIBBON RIBBON CONNECTOR I/O MODULE

The I/O RIBBON is used for easy connection of the IMR-98 to the optional IM-RELAY via ribbon cables. There are two ribbon connectors for up to two relay modules. The ribbon cables are attached using locking connectors to avoid inadvertent disconnection. The I/O RIBBON is an optional module and is not required when connecting to the relay module(s). The I/O STD may be used and the individual outputs may be wired by hand to the IM-RELAY.

I/O RELAY MULTIPLEXER RELAY I/O MODULE

The I/O RELAY is the I/O module for the IM-RELAY. This module contains a ribbon connector and the wiring terminal blocks and circuits required to pass 8 digital outputs from the multiplexer receiver to the dry contact relay module. The outputs may be wired by hand from the I/O STD or by ribbon cable from the I/O RIBBON.

F0-98-DIG FIBER OPTIC DIGITIZER MODULE

The F/O-98-DIG is an analog to digital, digital to analog converter that interfaces between the audio I/O's of the FSK modules and a fiber optic interface. The digitizer provides two inputs and two outputs for audio communication channels. Each I/O is capable of covering the entire audio spectrum, allowing multiple FSK modules to be connected to each I/O. The F/O 98-DIG connects directly to the I/O FO fiber optic module that contains the fiber optic heads and terminal blocks to wire to FSK receivers and/or transmitters.

I/O FO FIBER OPTIC DIGITIZER I/O MODULE

The Fiber Optic I/O module contains the terminal blocks to wire to FSK or multiplexer modules and the transmit and receive heads for a dedicated fiber. When converting an audio signal to fiber optic communications or vice versa, the F/O 98-DIG must be connected. The fiber optic digitizer acts as the A/D and D/A converter for up to two audio channels. When connected to a multiplexer receiver, transmitter, or other device with digital data, the F/O 98-DIG is not required. The digital device connects directly to the digital input or output points of the I/O FO. Laser and LED heads are available in 850 nm and 1300 nm multimode and 1300 nm, and 1550 nm single mode formats with ST or FC style connectors.

The IP-98 is the 98 Series power supply. The regulated switching power supply is available with various input voltages (115 VAC, 12 VDC, 24 VDC, 48 VDC, 125 VDC, or 250 VDC) and packages (3U rack mount, 1U rack mount, or Compact supply. All versions of the IP-98 provide a regulated +5 V, +15 V, and -15 VDC outputs that will power any module in the 98 Series. The IP-98 has 5000 VDC isolation from input to output on all models (except 12 VDC models). The standard 3U rack mount versions supply 55 W of power, all other IP-98's supply 20 W of power.

I/O PS POWER SUPPLY I/O MODULE

The I/O PS is the power supply I/O module. This module contains the wiring terminal blocks and circuits required to pass the inputs and outputs to the power supply module. The I/O PS is available in 3U and 1U versions. The I/O PS is not required when the IP-98 is supplied in a Compact chassis.
