ISM MTP UT 4DA Output Board Installation Notes
The Extron ISM MTP UT 4DA is a twisted pair transmitter board for the ISM 824 with four RJ-45
outputs, two RS-232 inserts, and local audio output.
The board mounts in one of the four vertical expansion
slots (numbered 1 to 4) at the rear of the ISM 824.
For full operating details of the ISM refer to the
ISM 824 User’s Manual, online at www.extron.com.
To install an output board in the ISM 824 base unit,
1. Turn off the ISM 824, and remove the power cord.
Repeat for all connected devices.
2. At the rear, select an open slot, or take out the
blank plate from the desired output port by
removing the two retaining screws (top and
bottom), and lifting the blank away.
N Re-use the screws to secure the new output
board in place. Retain the blank plates.
If a board is already installed in the desired slot,
remove the screws and carefully pull out the
board.
3. Remove the board from its outer box and anti-ESD
bag, holding the boards by the rear frame.
4. With the board upright, align the front (non connector end) of the board with the top and
bottom plastic guides in the ISM 824. Slide the board in carefully, keeping within the guides.
Push it home firmly, and secure it with the retained screws.
5. If applicable, repeat steps 2 through 4 for any other output boards.
6. Power on the ISM 824. The new output board(s) is auto-detected, and takes approximately
30 seconds to initialize. The LCD display indicates the new board type,
slot used, and counts down the initialization time. See inset for example
display for a new ISM MTP UT 4DA board installed in Slot #3.
7. Using suitable twisted pair cables connect any MTP
receiver, DA, or switcher to the RJ-45 twisted pair outputs
on the installed boards. See wiring details at right.
N Use the same standard at both ends of the twisted pair
cable.
8. Insert a 5-pole captive screw connector from an audio
device into the local audio output connector for balanced
or unbalanced stereo audio. Wire the connector as shown
below.
