- OPERATION
- Introduction
- Description
- Front Panel Controls
- Figure 1-5: Front panel of an EF-701M unit
- 1. ON- Either a successful data link has been established with a remote EF-701M unit, or the Matrix Direct mode has been selected at the local EF-701M unit.
- 2. OFF- There is no data connection at the local EF-701M unit.
- 3. RAPID BLINK- There is data connection at the local EF-701M unit, but a “break” condition is present. Depending on the modems used, this can indicate a problem at the remote end.
- 4. SLOW BLINK- A test earbud or headphone has been plugged into the test tone jack at the local EF-701M and the nulling test tone is on.

- Connecting the EF-701M Interface
- Connecting the EF-701M to a Matrix Port
- 1. On the EF-701M’s back panel, set mode-switch 1 to the ON position.
- 2. Connect a CAT-3, CAT-5, or above cable from the RJ-45 Matrix connector on the back panel of the EF-701M to a port (RJ-45) on the Matrix frame.
- 3. Program the Matrix port. Refer to the Eclipse Configuration System (ECS) Manual for instructions.
- Connecting the EF-701M to a Modem
- 1. Connect the local party-line channel to the EF-701M’s rear-panel 3-pin XLR connector.
- 2. Check to see that the EF-701M is receiving power by checking the green Power LED (the “on” light). If there is a powered EF-7...
- 3. Send a call signal and check that it is received at the distant intercom system.
- 4. Adjust nulls, and then check audio levels as required.
- 5. Repeat as necessary for each EF-701M in the system.

- Nulling
- 1. Connect all the local party-line devices for that channel together and to the EF-701M.
- 2. Plug into the front-panel earphone jack labeled “test.” You will now hear a steady 200-Hz tone through the earphone.
- 3. Adjust the “R” control until the tone is at its minimum.
- 4. Adjust the “L” control until the tone is at its minimum.
- 5. Adjust the “C” control until the tone is at its minimum.
- 6. Because these controls interact with each other, you will need to repeat steps 3, 4, and 5 several times before fully minimizing the test tone.
- 7. Continue these adjustments until the test tone is virtually inaudible.
- 8. Unplug the earphone when the nulling operation is complete.
- Internal Adjustments
- 1. Disconnect all cables.
- 2. Remove the four sheet metal screws on the back and sides.
- 3. The XLR jack has a special locking tab to secure it to the housing. The jack must be released before the cover can be removed...
- 4. Remove the two 3/16 in. hex-head jack screws on the DB-15.
- 5. Slide the cover backwards until the DB-15 and XLR jacks are clear.
- 6. Lift off the cover.
- 7. Make the necessary adjustments of jumpers P3 and P4 (shown in the following table).
- 8. For reassembly, reverse steps 1 through 6.
