1 Introduction DASDEC Interfacing to DM Engineering MSRA/MSRE Series Switchers The DASDEC-II EAS/CAP Encoder/Decoders include a single analog balanced-stereo audio switch for inserting an EAS/CAP audio message into the program stream 1. However, a single program switch is not sufficient to cover multiple audio program streams therefore combining the MultiStation-2 or MultiStation-5 software with an additional audio switch like the DM Engineering Multi Station Relay Adapter (MSRA) provides individually controlled audio insertion on multiple channels expanding the audio capabilities up to a total of four discrete channels. The MSRA is a compact three (3) channel stereo switcher providing a simple and low cost method to switch multiple channels of stereo analog audio signals with the EAS audio from a DASDEC without requiring an external audio distribution amplifier and cabling. Similarly the DM Engineering Multi Station Relay Expander (MSRE) provides three pairs (six total) of additional Form-C relays for controlling a wide variety of devices during and EAS event. A special cable (included with the MSRA) connects the DASDEC and MSRA for serial and audio inputs, while a DASDEC multi-turn recessed front panel Input Gain trim potentiometer and individual multi-turn Station Gain controls on the MSRA provide control over the active stereo distribution amplifier sections of each channel. A recessed front panel Test switch is also provided for aiding the setup of the audio levels.

2 4 Digital Alert Systems Setting up the MSRA/MSRE 1. The MSRA includes a special interconnecting cable combining both serial communications and audio inputs into a single RJ- 11 connector as shown in Figure 2. Use this cable to connect the auxiliary out DASDEC main serial port and the audio output of the DASDEC Figure 2. MSRA interconnecting cable. (Please refer to the MSRA/MSRE MSRA Interface Cable Schematic owner s manual for more information on wiring connections). 5. The Tally output is not required to be used for proper operation of the MSRA. It consists of an optically coupled open collector/emitter NPN 2.

3 6. To activate the serial port for each station (assuming either MultiStation- 2 or MultiStation- 5 has already been installed) go to Setup > Decoder > Forwarding then select the first station from the pull down menu the example below uses station named ABCD. 7. Once a station is selected scroll down the page for the activation table showing the various port and GPI s /GPO s paying particular attention to the left side menu for Active Orig/Fwrd Serial Ports. Select Main Serial Port that corresponds to the port the cable was connected in Step 2 and Aux1 Audio Output, and then click Submit Selection Settings to store the assignments. Important note: The same selection MUST be done for each station connected to the MSRA. DASDEC Interfacing to DM Engineering MSRA/MSRE Revision 1.0 Page 3 of 6

4 8. Next go to Setup > Video/CG > Main Serial and select the DM Engineering MSRA/MSRE Audio Switcher button. 9. In the section immediately below are columns corresponding to the MultiStation configuration labeled Base Station and Station 1 through Station 5 depending on which MultiStation license is active (e.g. under MultiStation- 2 there would be only 2 station options). Within each column are numbers 2, 3 & 4 relating to the MSRA channels, understanding channel 1 is the DASDEC s internal switch. 10. Select the Station and MSRA switch combination by clicking on the switch number in each station column. An easy configuration idea is to assign Station 2 to switch 2, Station 3 to switch 3 and so on as shown below. While it may appear strange for Station 5 to appear it is shown because under MultiStation 5 the DASDEC will show all options. 11. IMPORTANT NOTE: To assure all channels switch to the Base Station during an EAN or any other master function, you must select all channels in the Base Station column. Do this by holding down the Control key (CNTL) then clicking (select) each number in the Base Station column. DASDEC Interfacing to DM Engineering MSRA/MSRE Revision 1.0 Page 4 of 6

5 12. Each serial port has the ability to specifically trigger based on FIPS and EAS event codes. Since these filters are most likely already in the MultiStation configuration it is most likely setting these filters are redundant and unnecessary. Changes here should only be done if the serial port control to the MSRA is desired for a very specific FIPS location or EAS event code, otherwise it is best to leave them in the default configuration. 13. In the same manner the triggering for the serial communication can be gated using a GPI Filter Configuration and unless there is a specific need it is best to leave it with the default DO not use GPI triggers selected as shown below. 14. When completed with stations and switch selections click on Accept Changes. DASDEC Interfacing to DM Engineering MSRA/MSRE Revision 1.0 Page 5 of 6

6 Setting up DASEC and MSRA for bonded channels Another useful setup for the DASEC and MSRA combination is bonding switches together. This DASDEC configuration is useful when simultaneous switching of more then one channel is desired such as a television Secondary Audio Program (SAP) channel, or when programs may be fed from alternate sources, but the EAS message should go out at the same time. This can be simply depicted as shown in Error! Reference ource not found. and can be configured anytime multiple station insertion or wanting to switch multiple channels associated with a station.

After logging in to the DASDEC go to Setup > Video/CG > Main Serial and to the Station / Switch assignment section. By holding down the Control (CTL) key multiple switches may be selected in each Station column. Using this feature the DASDEC will trigger the switches as assigned to each station. The example above will have Station 1 triggering both the DASDEC internal program switch AND the MSRA channel 2 switches at the same time. Station 2 will simultaneously trigger MSRA switches 3 and 4. Stations 3, 4, and 5 are not assigned an external switch in this example, or may be configure on another device. 2.
