User manual RANE RPS 4

[. . . ] RPS 4 Remote Program Selector In some applications, it may be desirable to switch the MPE programs from a remote location, without the use of a computer or MIDI controller. A simple switch to change programs can also make operation a lot easier for the non-technical person who may be responsible for operating the sound system. Simply, the RPS 4 converts contact closures to MIDI program changes. [. . . ] It will supply four program changes to the MPEs using any 3 conductor cable. Here's an actual size drawing along with the wiring diagram. 18 Rane MPE Users Guide Here is a wiring diagram to use with momentary contact pushbuttons with optional LED indicators. This idea can be used for 2, 3 or 4 program changes. Using a binary encoded switch, 16 MIDI program changes can be activated. A four pole, sixteen throw switch can also be used. A switch with fewer positions (such as an eight throw switch) may be used by omitting the extra connections. Use of the RPS 4 is pretty obvious and shouldn't present any problems. Connect a MIDI cable (standard 5-pin DIN) between the MIDI OUT jack on the RPS 4 and the MIDI IN jack on the MPE. When controlling more than one MIDI unit at a time, connect the RPS 4 MIDI OUT jack to the MIDI IN jack on the first MPE, then connect the MIDI THRU jack from the first MPE to the MIDI IN jack on the second MPE, and so on. MPE MIDI OUTs won't carry the program change. ) 2. If controlling an MPE, disconnect the power supply cable from the red POWER jack on the MPE and reconnect it to the POWER jack on the RPS 4. Next, using the cable supplied, connect the POWER OUT jack on the RPS 4 to the MPE's red POWER jack. All other applications require using the optional Rane RS 1 remote power supply (NOT SUPPLIED). Connect the RS 1 to either red POWER jack. Use the MIDI CHANNEL SELECTOR to set the desired channel. All units being controlled must use the same MIDI channel. [. . . ] As the name implies, this is the correct position when using momentary pushbuttons to change programs. Changing the jumper to the BINARY position allows using the minimum number of interconnecting wires. Sometimes this represents a significant cost savings and convenience.
