INTRODUCTION

An Overview of the ISP-100

Thank you for choosing the ISP-100™ for your signal processing needs. The ISP-100 is the first in a line of high quality signal processing products from TELEX Communications, Inc.’s Merlin division. The ISP-100 represents a continued commitment to understanding and meeting our customers needs through the development of innovative and intuitive solutions.

The ISP-100 is designed with flexibility in mind, which results in a powerful tool that allows you to adapt to ever-changing markets and applications. The utmost in quality is also a prime directive in the design and manufacture of this product.

A series of predefined signal path topologies called QuickMAPs™ are offered which enable the designer to quickly define the system’s processing structure. This approach allows for a continuation of new processing solutions and/or variations that provide “market specific” templates to help minimize your design time and increase your profit.

This single rack space unit can replace a multitude of traditional analog components. Time and money savings are realized in reduced labor costs for wire harnessing, rack size, assembly, and minimized failure due to reduced interconnection. As a result of this consolidation of processing, overall system performance and audio integrity is greatly increased.

1-1

The four in eight out configuration is only possible when the second card slot contains a digital I/O card.

An ergonomically designed software interface called VUE-IT™ provides graphic control panels with the conventional look of signal processors, as well as an advanced and easy to use filter tool panel which graphically displays the configuration of your filter block settings.

One of the most impressive and unique features of the ISP-100 is the configurable input/output (I/O). This feature allows the designer or installer to select between analog input or output modules, and/or a digital input/output combination module. These modules are two channel units and can be intermixed between analog and digital, thus providing a variety of I/O combinations. The ISP-100 supports a maximum of four inputs and eight outputs. The inputs and outputs can be either analog, digital, or a combination of both.

Because of our commitment to providing the utmost in audio quality the dynamic range of the ISP-100 rivals anything currently on the market.

The ISP-100 has a typical noise floor of –110 dBu and a typical THD+N of <0.004%. Propagation time is minimized in the ISP-100. No more than two milliseconds of delay is introduced from any analog input to analog output with full processing and delay set to zero.

The ISP-100 is flexible. A General Purpose Interface (GPI) allows multiple system configurations to be selected without the need of a PC to control the unit. This is accomplished through user-supplied contact

closures. This interface allows users to change system settings directly and/or scroll through various settings.

Serial Communications

Serial communications with the ISP-100 can be accomplished either through the DB-9 connector located under the front panel security cover or through the RJ-45 connector located on the rear panel. The computer connected to the ISP-100 must have a free COM port (1-4). Communications with the ISP-100 will not work properly if the COM port is shared with another device such as a TEF™ analyzer. It is important to set the serial port selection switch located under the front panel security cover to the serial port used. The cable used should be of low capacitance and suited to data communications.

Front Panel RS-232

When tuning the system with a computer controled analyzer use a separate computer for the analyzer. Using two PCs will save time.

RFI choke data.

RFI choke such as Steward PN: 28B2025-0A0 should be used at the ISP-100 end of the cable. See Figures 2-13 and 2-16, and Table 2-1 for more information.

Rear Panel RS-232

The serial port selector switch should be set in the up position. If the PC’s COM port is a DB-25 connector, wire the cable according to Figure 2-14. If the PC’s COM port is a DB-9 connector, wire the cable according to Figure 2-15. No RFI choke is needed. See Figure 2-16 and Table 2-1 for more information.

RS-232 cable runs over 50 feet could cause unreliable communications. It is better to use RS-485 converters for connections over 50 feet. Be sure to read the application note on this topic before buying converters.

Connections Over 50 Feet

The EIA specifications for RS-232 communications allow for connections up to 50 feet. For longer connections, the RS-232 signals must be converted to a standard, such as RS-485, that is tolerant of long distances. The converter on the PC end of the connection can be PC powered, but the converter at the ISP-100 end of the connection must have its own power supply. Before buying converters please contact TELEX Communications, Inc. for an application note on this topic.

Diagnostics

Table 3-1

The ISP-100 was designed with built-in diagnostics that activate when power is applied to the unit. During the power-up cycle, the ISP-100 performs several self-checks. The ISP-100 also will report problems, as they happen, while the unit is running. The diagnostic messages are communicated through the front panel LEDs. Refer to Table 3-1 for a list of common LED conditions and corresponding diagnostic messages.

LED diagnostic messages.

Factory Default Mode

A yellow host LED indicates factory default mode. This mode usually results from either an OS update or memory erasure. When in this mode a default QuickMAP and QuickSET are loaded that prevents the unit from passing damaging signals. The QuickMAP configures the ISP-100 as a straight through processor with high pass filters on the outputs. The corner frequencies of the high pass filters are set to 20 kHz.

To enter factory default mode, hold in the default switch (see Figure 2-1, item 6) while turning on the power. Continue to hold in the switch until the front panel LEDs turn red and begin to rotate.

Note that when the factory default QuickMAP is loaded one or more slot LEDs may blink yellow. This is normal operation and not an error.

Changing the Fuse

The universal switching power supply in the ISP-100 adapts to input voltages from 90 to 264 VAC, 50/60 Hz. To reduce risk of fire, replace only with same type fuse. The fuse holder is located under the security cover on the front panel.

The fuse is a standard 20mm X 5mm European type. The values used are as follows:

All countries using 220/240 VAC, except Australia, use a ½ A slow-blow fuse.

Schurter P/N: 0001.2501 Telex P/N: 51-04-052488

All countries using 100/120 VAC and Australia use a 1 A slow-blow fuse.

Schurter P/N: 0001.2504 Telex P/N: 51-04-051487

Changing the Battery

WARNING:

Disconnect AC power before changing the fuse. Failure to do so could result in a shock hazard.

WARNING: Failure to install the proper fuse could result in damage to the unit, property, and loss of life.

Figure 3-3

The memory backup battery located under the security cover on the front panel has an expected life of four years. If the Host LED is blinking the battery needs to be changed.

CAUTION: The battery used in this device may present a risk of fire or chemical burn if mistreated. Do not recharge, disassemble, heat above 212°F (100°C) or incinerate. Replace battery with Renata CR2450N or MERLIN 40-02-052055 only. Use of another battery may present a risk of fire or explosion.

Be sure to change the battery with the unit on. If the unit is turned off, all of the setup information stored in the ISP-100 will be lost (i.e. the unit will return to factory default mode).

10 July 1998

Battery/module removal tool.

Leave the AC power connected and the ISP-100 turned on when changing a failed battery. Failure to do so will result in loss of data.

3-5

Saving the ISP-100 configuration data to disk will guard against the loss of data in the event AC power fails before a failed battery has been changed.

Caution: Use only the tool attached to the inside of the security cover to change the battery. The tool is black anodized so it will not short out the battery or anything else. DO NOT under any circumstance use pliers to grip the battery. Doing so could cause damage. See Figure 3-3.

Replace the battery with a Renata CR2450N battery. Replacement battery/module removal tools as well as replacement batteries are available from Telex. Their part numbers are:
