slot in the button plate until the membrane containing the button is free.
7.
To replace the button, align the two pegs in the button membrane with the holes located
at opposite corners of the empty slot on the back of the button faceplate and push the
button forward so it fits in the desired slot (see the figure to the right). Ensure the button
text orientation is correct.
8.
Align the back of the button plate with the control plate and press it into place. The four
tabs released in steps 2 through 4 snap back into place.
9. Ensure the plastic faceplate and metal mounting plate are in the correct orientation. To
reattach the plastic faceplate, press the faceplate back into the metal mounting plate,
using the two catches released in step 1 on the previous page.
Step 4: Set Bus ID Address
Set the bus identification (bus ID) DIP switches for the ACP VC1 EU/MK and any other ACP
panels being connected to the system. Each ACP device must have a unique bus ID. If multiple panels have the same bus ID,
address conflicts may cause one or more of the panels to not be recognized in DSP Configurator or by the host device. Up to
eight ACP devices can be connected in the same system.
ACP Ports
• Connect up to four (4) ACP endpoint devices per
DMP 128 Plus.
• Wire the connectors the same at both ends.
• These ports are identical. You can connect devices
interchangeably to either port.
• Do not exceed a total of 1000 feet (305 meters) of cable for
connections between the DMP 128 Plus and all of the ACP
panels.
• Power is provided by the DMP 128 Plus, a PS 1220EB
power inserter, or an Extron 12 VDC power supply.
Bus ID Address DIP Switches
• Use these DIP switches to set the six-bit, binary
bus address for the ACP VC1 EU/MK.
• Each ACP connected to the same DMP 128 Plus
must have a unique address.
• Switch 1 (on the left) is the highest value (32, the
the most signi cant bit [labeled "MSB"]).
• Switch 6 (on the right) is the lowest (1, the least
signi cant bit [labeled "LSB"]).
• Up = on = 1, Down = off = 0
