Installing the MDC-2100/MDC-900

In order to use the MDC with the OSCOR, a special connector (the OEP-2100) must be installed in the connector tray of the OSCOR. This connector should be installed permanently into the connector tray and provides for easy connection of the MDC while not affecting the OSCOR normal operation. Note the step numbers on Figure 4 below to assist in the installation.

To install the OEP-2100:

1.Turn the OSCOR off and wait at least 30 seconds before proceeding.

2.Remove the OEP from the packaging and insert the mini-din connector (OSCOR EXP.) into the EXPANSION PORT of the OSCOR as shown in Figure 4. (You may have to unplug the two tape recorder cables labeled REMOTE OUT RECORDER).

3.Insert the metal support bar into the connector tray. Align the depression at the center of the bar with the screw head at the top of the OEP. (The cables that provide connection to the tape recorder controls must be placed under the metal support.)

4.Use the hex wrench to tighten the two hex screws. (This holds the OEP in place.)

5.Unplug the HF/UHF BNC connector from the OSCOR and plug it into the OEP at the ANTENNA PANEL RF jack.

6.Connect the OEP BNC cable (HF/UHF INPUT) to the OSCOR HF/UHF INPUT.

To install the MDC-2100 or MDC-900:

1.Plug the MDC BNC connector into OEP BNC jack (MDC RF).

2.Plug MDC mini-din connector into the MDC POWER/CTRL jack.

3.Utilize the OSCOR keypad to control the MDC.

Figure 4: INSTALLATION OF THE OEP

The MDC can be used in a stationary position sitting on the provided tripod or it can be moved around the environment to provide a thorough sweep of the area. For best operation, the MDC should be located at least three feet away from the OSCOR. Position the metal housing towards the OSCOR.

A good rule of thumb is to assume that the MDC has an antenna pattern that is about 100 degrees wide. In other words, it is necessary to point the MDC in at least 4 different directions around the room to cover the perimeter. Also, the MDC should be pointed up and possibly moved around the room to cover the ceiling, and down to cover the floor. Furthermore, if you expect a very sophisticated threat, it is recommended to point the MDC into ducting, above ceiling tiles, and in any enclosed spaces in which it would be possible to place a transmitter with a high gain antenna. It is highly recommended that the “Show All” mode of operation for the MDC-2100 be utilized MDCA-all and MDCB-all if using OSCOR 5.0. When a signal is detected, the user can then manually select the different antenna bands and filters to further investigate the signal. Or, the user can simply go to the analyze mode and allow the MDC to determine the operational frequency of the transmitter. Also, it is not recommended to use the MDC with the OSCOR automatic mode unless the MDC directional characteristics are taken into consideration. If running the OSCOR and MDC in the automatic mode, take care to enable the appropriate MDC spans. To maximize usage of the MDC, include MDC 3-21GHz Filter A and MDC 3-21GHz Filter B in your span list For OSCOR 4.0 users, set span to All Bands A&B Using the MTU-2100 Microwave Test Unit Specifications MDC-2100/MDC-900 SPECIFICATIONSMDC-2100 MDC-900Technical Bulletin
