CHAPTER 1

Description and Specifications

General Description

The DSI 2008 Dual Digital Hybrid interfaces two, 2-wireintercom lines to two,4-wireintercom lines. Unlike earlier analog hybrids, the DSI 2008 features advanced digital signal processing to achieve automatic nulling of the2-wirelines. Plus, each hybrid features convenientpeak-readinglevel meters to quickly match the levels between the lines that are being interfaced.

The result is easy and accurate setup. With the DSI 2008, all need for test tones, nulling adjustments and ducking adjustments have been eliminated.

Compatible 2-wireintercom systems include RTS™ TW, Audiocom®, andClear-Com®.Compatible4-wireintercom systems include Telex’s ADAM™, ADAM CS™, and Zeus™ Digital Matrix Intercom Systems.

The DSI 2008 is also available with optional call signal interfacing. This option provides bi-directionalcall signal compatibility between the2-wireand4-wireintercom systems.

With features like digital signal processing, peak-readinglevel meters and option call signal interfacing, the DSI 2008 Dual Digital Hybrid assures ease of setup maximum transparency between intercom systems.

Features

Two Independent Hybrids: Interface two separate2-wirelines to two separate4-wirelines.

Automatic Nulling: Digital hybrids eliminate all nulling and ducking adjustments. Quick,trouble-freesetup. Puts an end to concerns about echo and feedback when interfacing2-wirelines.

Peak Reading Level Meters: Quick and accurate visual audio level adjustment. No extra setup equipment or guesswork is required.

Direct ADAM/Zeus Audio Connection: Accepts standard ADAM/ZeusDB-9orRJ-11keypanel cables.

Transformer Isolated: All audio inputs and outputs are transformer isolated to prevent ground loops and hum.

Call Signal Option: Detects call signals from any of the compatible2-wireintercom systems, and then provides a +5 VDC output to the4-wireintercom system. Accepts a contact closure input from the4-wiresystem and converts it to the call signal format required by the2-wiresystem. The DSI 2008 can be directly connected to an ADAM, ADAM CS, or Zeus GPI (General Purpose Interface). GPI inputs can be programmed to activate call signals and audio paths to any of the available types of communication with the4-wiresystem, including intercom ports, camera ISO circuits, IFB circuits, etc. GPI outputs

1

can be set up to place calls only from a specific keypanel within the 4-wiresystem, or from any keypanel within the4-wiresystem that wishes to call the2-wiresystem.

Half-rack Wide, 1RU High: Two DSI 2008s fit into a single rackspace. Compatible with RTS TW rack mount hardware. Can be mixed with other TW equipment.

Universal Power Pack: Ready for worldwide use. Automatically accepts any main voltage from100-250VAC, 50/60 Hz. Power pack equipped with locking DIN connector for attachment to the DSI 2008.

FIGURE 1. DSI 2008 Reference View

Front and Back Panel Descriptions

Front Panel

There is a power ON/OFF and call indicator at the left of the front panel. This indicator lights continuously when the DSI 2008 is turned ON and flashes when an incoming call signal is detected, if the call signal option board is installed.. The remainder of the front panel is divided into controls and indicators for the two separate hybrids, labeled SYSTEM A and SYSTEM B. For each hybrid, there is a 10-segment,peak reading level meter to display the4-wireoutput level (TO 4W). There is a recessed level set control to the left of the4-wiremeter (LEVEL SET) and there is also a recessed,5-positionrange select control for the4-wireoutput (4W LEVEL REF SEL). Under the4-wiremeter, is an identical meter for the2-wireoutput level, and there is a recessed level set control for the2-wireoutput to the left of the meter. Under the2-wiremeter, there is a recessed, 5- position selector. The selector has two OFF positions for when no2-wireinput is connected. The three remaining switch positions select the2-wiresystem as follows: position 1 selects RTS TW channel 1; position 2 selects RTS TW channel 2 or aClear-Comchannel; the BAL position selects an Audiocom balanced channel. There are 3 LED indicators to display the current selection.

2

Back Panel

The power pack connector is located at the right end of the back panel. This is a locking DIN connector. The remainder of the back panel is divided into connectors for the two separate hybrids. Connectors are labeled with “J” numbers followed by “A” or “B” to indicate System A or System B. For each hybrid, there is an AUX connector. This is used to connect to/from the optional call signal card. Below the AUX connector, there are both a DB-9Fconnector and anRJ-11connector for4-wireintercom connection. These are directly compatible with standard ADAM/Zeus keypanel cables. Next to the4-wireconnectors, there is a3-pinfemale XLR audio connector for connection to the2-wireintercom system.

Installation

Mounting

Place the DSI 2008 on a desktop, or install it in an equipment rack using an RTS MCP Rack Mount Kit. Several rack mount options are available. There are no special ventilation requirements for the DSI 2008, but allow for ventilation around the power pack.

If the DSI 2008 has the call signal option, the power indicator flashes whenever a call signal is received from either 2-wireline, and activity on the level display helps to indicate which line is calling. If the DSI 2008 is physically positioned near the4-wireoperator, this can be used as an incoming call indication for the4-wiresystem, if desired (although other methods are available as described in“4-WireCall Signal Connections” on page 10).

NOTE: You may wish to read about the internal mode DIP switches before mounting the DSI 2008. For further information, see Table 3 on page 20.

4-WireAudio Connections

ADAM, ADAM-CS,or Zeus Audio Connection

1.Use standard 9-pinorRJ-11keypanel cables. Connect from one port of your intercom system to J2A or J3A (System A connection) on the back of the DSI 2008. Connect from another port to J2B or J3B (System B connection).

2.On the DSI 2008 front panel, set the 4W LEVEL REF SEL switches to the +8 dB position.

5

Audio Connections for the Other 4-wireCommunications Systems

1.Construct 9-pinorRJ-11cables to connect from the4-wiresystem to the DSI 2008. To connect to the System A hybrid, use either J2A or J3A; for the System B hybrid, use either J2B or J3B. Pin connections are as follows:

FIGURE 2. Rack Mount Configurations

2-WireAudio Connections

RTS TW Audio Connections

1.Use standard TW intercom cables. Standard TW system cables can carry either one or two channels, while each hybrid in the DSI 2008 can only interface one TW channel to one 4-wirechannel, which channel is determined by the front panel 2W CHAN SEL switch. If your TW system cable is only carrying one channel, or if you only need to connect one of two channels, connect directly to J1A (System A) or J1B (System B). If your TW system cable is carrying two channels, and you want to connect to both, use aTW-5Wor similar device as shown in Figure 3 on page 8.

7

NOTE: The DSI 2008 features internal DC isolation. You can therefore connect to the DSI 2008 to powered TW cables, and it will not draw any power from the TW system.

2.On the DSI 2008 front panel: For System A and System B, set the 2W CHAN SEL switch to the appropriate position. To interface to TW channel 1 select position 1; for TW channel 2, select position 2.

NOTE: If the System A or System B will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector.

FIGURE 3. Using aTW-5Wto connect to two TW channels to the DSI 2008

Audiocom Audio Connection

1.You can directly connect standard Audio 1-channelcables. Connect one Audiocom channel to the J1A connector on the back of the DSI 2008 (System A). Connect a second Audiocom channel to the J1B connector (System B). If your Audiocom system uses

2-channelcables, use aJB-2Junction Box to split the channels (Figure 4)

NOTE: The DSI 2008 features internal DC isolation. You can therefore connect the DSI 2008 to powered Audiocom cables, and it will not draw any power from the Audiocom system.

2.On the DSI 2008 front panel, set the 2W CHAN SEL switches for System A or System B to the BAL position.

NOTE: If System A or System B hybrid will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector.

8

FIGURE 4. Using aJB-2Junction Box to split a2-channelAudiocom cable into two1-channelcables.

Clear-ComAudio Connection

1.Use standard Clear-Com3-pincables. Connect oneClear-Comparty line to the J1A connector on the back of the DSI 2008 (System A). Connect a separateClear-Comparty line to the J1B connector (System B).

NOTE: The DSI 2008 features internal DC isolation. You can therefore connect the DSI 2008 to poweredClear-Comcables, and it will not draw any power from theClear-Comsystem.

2.On the DSI 2008 front panel, set the System A and System B 2W CHAN SEL switches to position 2.

NOTE: If the System A or System B hybrid will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector.

Other 2-wireAudio Connection

1.Use the J1A connector on the back of the DSI 2008 to connect one 2-wireline to the System A hybrid. Use the J1B connector to connect a second2-wireline to the System B hybrid. The pin configuration for the J1A and J1B connectors depend on whether you are connecting a balanced or unbalanced2-wireline, as follows:

NOTE: TW systems must provide termination on the audio channel.

Balanced Configuration

Pin 1 No Connection

Pin 2 Balanced Audio + Input/Output Pin 3 Balanced Audio - Input/Output ** Termination 300 Ω

There are two possible configurations for unbalanced connection:

Unbalanced Configuration 1

Pin 1 Audio Common Pin 2 Audio Input/Output Pin 3 No Connection

** Termination 200 Ω

9

Unbalanced Configuration 2

Pin 1

Audio Common

Pin 2

No Connection

Pin 3

**Termination 200 Ω

2.On the DSI 2008 front panel, set the CHAN SEL switches as follows:

Balanced Configuration: set the CHAN SEL switches to the BAL position.

Unbalanced Configuration 1: set the CHAN SEL switches to position 1.

Unbalanced Configuration 2: set the CHAN SEL switches to position 2.

NOTE: If System A or System B will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector.

4-WireCall Signal Connections

NOTE: These connections require the call signal option.

Call Signal Connection for ADAM, ADAM CS, and Zeus

You can use the General Purpose Interface (GPI) connector to interface call signals. The pin-outof the connector is the same for all of these intercom systems Table 1 on page 11.

ADAM GPI Connector: XCP-ADAM-MC, J11

ADAM CS GPI Connector: J903

Zeus GPI Connector: J27

If your intercom system is equipped with a UIO-256(Universal Input/Output) Frame, you can also use that for connections (Table 1 on page 11 and Table 2 on page 12).

As an alternative to using the GPI, you can use external components to send and receive call signals as described in “Call Signal Connections for other 4-wireCommunications Systems” on page 13.

Typical GPI connections are shown in Figure 5 on page 11. The example uses GPI outputs #1 and #2 and GPI Input #1. You may substitute other GPI Input and Outputs.

IMPORTANT: AZedit version 1.06 or higher includes a feature which allows you to invert the action of the GPI outputs. By default, these output are set to duplicate the action of the RTS FR9528 Relay Frame accessory. This is the correct setting for use with the DSI 2008. To check the AZedit setting, select Intercom Configuration in the Options menu. Click on the Options tab, then verify thatConfigure onboard GPI outputs in FR9528 mode is selected.

10

FIGURE 5. Call signal connections for ADAM, ADAM CS, and Zeus Intercom Systems. This example uses GPI outputs #1 and #2 and GPI Input #1; however, you may use any other available GPI inputs and outputs. The Call Enable/Inhibit connection is optional. It gives you the ability to disable call signalling using a GPI output. However, when connecting to aClear-Comintercom system, if an enable/inhibit switch is not connected, a jumper must be installed for any other application. You DO NOT have to use GPI outputs for call signalling or enable/inhibit, you can use simple switches instead, as shown in Figure 6 on page 13.

Call Signal Connections for other 4-wireCommunications Systems

4-wireCall Send and Call Enable/Inhibit

The DSI 2008 accepts a switch-contactinput from the4-wiresystem and then generates a call signal output to the2-wiresystem. The DSI 2008 also accepts an optional switch contact input to enable or inhibit call signaling between the4-wireand2-wiresystems. Figure 6 shows the typical connections.

FIGURE 6. Typical call send and call enable/inhibit connections for a4-wireintercom system.

13

4-wireCall Receive

The DSI 2008 receives call signals from the 2-wiresystem, then converts this to relay contact closure for use as a4-wirecall receive indication. The DSI 2008 also provides +5 VDC which can be connected to the relay contacts to generate a DC output signal instead of a contact closure. Connections for a simple contact are shown in Figure 7 on page 14.

FIGURE 7. Call signal connections for a4-wireintercom system other than ADAM, ADAM CS and Zeus.

2-WireCall Signal

Call Signal Connections for Audiocom, RTS TW and Clear-Com

The call signals are superimposed on the audio signal, so no separate call signal connections are required. However, make sure that a call enable switch or jumper is installed for Clear-Comapplications as shown in Figure 6 on page 13 and Figure 7.
