Rocktron Chameleon On-Line - Manual (Page 10)

7
8 PHANTOM POWER jack
This 2.5mm PIN jack offers the ability to power Rocktron MIDI foot controllers from a 7-
pin MIDI cable which connects from the Rocktron MIDI foot controller to the MIDI IN
jack on the rear panel of the Chameleon. This eliminates the need to find an AC outlet
near where the footpedal would be placed during a performance, or the need to run an
extension cord out to the footswitch. Instead of inserting the AC adaptor into the
"POWER" jack of the footswitch as you would normally, plug it into the "PHANTOM
POWER" jack on the Chameleon. This will power the Rocktron MIDI foot controller
through pins 6 and 7 of the MIDI cable connecting the two units. A 7-pin MIDI cable must
be used and is available from your Rocktron dealer.
9 MIDI IN jack
This 7-pin DIN connector must be connected to the MIDI OUT jack of the transmitting
MIDI device via a standard MIDI cable, or to the MIDI THRU jack of the preceding
device (if the Chameleon is within a chain of MIDI devices).
Pins 6 and 7 of this connector carry the phantom power to power a Rocktron MIDI foot
controller when a 7-pin MIDI cable is used.
10 MIDI THRU/OUT jack
This standard 5-pin DIN connector can be connected to the MIDI IN jack of another
device via a standard MIDI cable. There are limitations to the number of devices that can
be chained (or series connected) in this fashion.
Note: Inherently in MIDI there is a limit to the number of devices which can be chained
together (connected in series). With more than 3 devices, a slight distortion of the MIDI
signal can occur (due to signal degradation) which can cause an error in MIDI signal
transmission. Should this problem arise, a MIDI Thru box can be used which connects
directly to the MIDI device which transmits MIDI information and has multiple connec-
tors for the multiple devices receiving MIDI. MIDI cables should not exceed 50 feet (15
meters) in length.
11 POWER jack
This 4-pin DIN connector accepts power from the 9VAC adaptor supplied with the unit.
