2-Series Integrated Dual Bus Control System Crestron AV2 & PRO2
bussing strips are constructed with four terminal block positions and may be
trimmed to size for various applications or different devices. One strip is supplied for
each 8-position terminal block.
1. To utilize the bussing strip, determine the number of relays to be
commoned for the equipment being installed. If less than four, the strip can
be trimmed to size with a pair of scissors or wire snips.
2. Loosen the terminal block screws and insert the first leg of the bussing strip
into the first common position of the terminal block. The strip engages the
other common positions automatically.
3. Remove approximately 1/8” of the jacket from the common wire and insert
the conductor into one of the terminal block common positions. Tighten the
terminal block screws to lock the wire and bussing strip into place. Insulate
the strip by folding a piece of ¾” wide vinyl electrical tape (such as Scotch
33+) over the spine and as much of the individual legs as possible. Excess
tape at each end of the strip should be pressed closed, then trimmed to
within approximately 1/16” of the end of the strip.
4. When wiring the remaining conductors, remove approximately 1/8” of the
jacket and insert the wires into the proper terminal block positions. To
prevent the possibility of electrical shorts, it is essential that these
conductors do not touch any uninsulated portion of the bussing strip.
5. Securing a tie wrap around the bussing strip is a useful way to provide
strain relief for the wires connected to the terminal block.
Memory Card Installation The onboard 36 MB memory of the 2-Series integrated dual bus control system is
enhanced with a 4 GB expansion slot that supports off-the-shelf Type II compact
flash memory and “microdrive” devices. The slot is accessible on the rear panel of
the unit. Complete the following procedures to install the memory card. Power does
not have to be disconnected to insert memory. Note that compact flash memory
supports FAT file structure.
1. Loosen the screw that secures the memory slot cover located to the left of
the COMPUTER port on the rear panel.
2. Pull on the screw to remove the screw and cover.
3. Observe handling precautions of the memory card manufacturer and insert
card into the open slot.
4. Align and reposition cover over slot and tighten the screw.
Memory Card Removal Complete the following procedures to remove the memory card. Power does not
have to be disconnected to remove memory.
1. Loosen the screw that secures the memory slot cover located to the left of
the COMPUTER port on the rear panel.
2. Pull on the screw to remove the screw and cover.
3. Press the eject button located on the extreme right of the slot.
4. Observe handling precautions of the memory card manufacturer and
remove card from the slot.
5. Align and reposition cover over slot and tighten the screw.
