P age 2 P age 3 R/C Manual 1. R/C OVERVIEW CONTENTS 1. Overview of R/C (Remote Control) — 3 1.1 R/C INTERFACE CONNECTORS — 3 1.2 R/C INTERFACES — 3 1.3 CONCEPT OF BANKS & CONSTELLATIONS — 4 1.4 HARDWARE R/C — 5 1.5 COMPUTER R/C — 5 1.6 COMBINED R/C — 6 1.
P age 2 P age 3 R/C Manual 1. R/C OVERVIEW 1. Overview of R/C (Remote Control) 1.1 R/C INTERF ACE CONNECTORS Only ONE source of control is accepted. Front panel selection of MIDI or LAN must be made on each 1788A. The 1788A always wakes up in the last mode used.
P age 4 P age 5 R/C Manual 1. R/C OVERVIEW Indirect MIDI Control MIDI controllers can access 1788A ’s through the LAN indirectly by interfacing with one or more 1788A-R’s.
P age 4 P age 5 R/C Manual 1. R/C OVERVIEW A CONSTELLATION refers to the whole array of preamps attached to the same LAN. It may comprise only one 1788A or up to 128 of them. Preamps may be assigned NET numbers placing them in different banks even when any given bank is not filled.
P age 6 P age 7 R/C Manual 1. R/C OVERVIEW Preset Management Software-managed presets are more extensive than using hardware controllers. Individual channel labels, group labels, and preset naming of up to 128 characters each in file save mode and 16 characters each in hardware save mode is supported.
P age 6 P age 7 R/C Manual 1. R/C OVERVIEW Management Extents Storing and recalling presets can be done only by remote control. Recalling presets can be done by indirect MIDI as well as by the 1788A-R and the PC software R/C. The extent of preset management depends on the form of R/C according to the table below .
P age 8 P age 9 R/C Manual 2. USING MIDI The software remote can handle communications with all 1788A ’s in the constellation directly . Even when one or more 1788A-R’s are detected, the software directly transmits control to all 1788A ’s. It also communicates with all 1788A-R’s to keep them synchronized.
P age 8 P age 9 R/C Manual 2. USING MIDI 2. Using MIDI 2.1 DIRECT MIDI CONTROL MIDI control can be piped directly to a 1788A ’s MIDI Input port from any suitable controller .
P age 10 P age 11 R/C Manual 2. USING MIDI 2.1.4 Understanding Ch, Dev and Net Offsets Please observe two important facts about MIDI Channel, Device, and Net Numbers. 1. All three are displayed in decimal form on the 1788A and 1788A-R front panels. Ch and Dev go from 01 to 16 and Net goes from 001 to 128.
P age 10 P age 11 R/C Manual 2. USING MIDI NOTE: We will refer to the Reference Data at the end of this chapter for command codes used by the 1788A. When programming each control, use the following setup: 1. Single-byte transmit 2. F aders: string; Buttons: string toggle 3.
P age 12 P age 13 R/C Manual 2. USING MIDI additional 1788A is used, the second set of eight faders and buttons of the PC1600 could be coded exactly like the previous tables, except with the channel and/or device number changed to match the second 1788A .
P age 12 P age 13 R/C Manual 2. USING MIDI 2.2 INDIRECT MIDI CONTROL If you want to employ a MIDI form of control when the 1788A ’s are connected to R/C units by LAN, direct connection to the 1788A ’s MIDI ports cannot be used. This is because only one R/C medium can be accepted by the 1788A at a time: LAN or MIDI.
P age 14 P age 15 R/C Manual 2. USING MIDI 2.2.1 Hardware Hook-up Anything from a single 1788A to a large constellation can be controlled by indirect MIDI through 1788A-R’s. Figure 2-5 suggests how this is done. The controller’s MIDI OUT is connected to the first 1788A-R’s MIDI IN.
P age 14 P age 15 R/C Manual 2. USING MIDI 2.2.3 Expanding the SysEx String Just like direct MIDI control, you can repeat 3-byte commands within the parametric SysEx string to send multiple commands to a single 1788A as shown by figure 2-7. NOTE: Y ou cannot expand the 2-byte MIDI Preset string.
P age 16 P age 17 R/C Manual 2. USING MIDI handled. 2.3 MUL TIPLE MIDI CONTROLLERS It should be normally possible to combine SysEx commands from more than one MIDI controller .

P age 20 P age 21 R/C Manual 3. 1788A-R HADRWARE REMOTE 3. 1788A-R Hardware R/C Unit (“HRemote”) 3.1 PURPOSE Although one or more 1788A ’s can be remotely controlled by a software program running on a computer , there are times when a dedicated hardware remote control is preferred.
P age 22 P age 23 R/C Manual 3. 1788A-R HADRWARE REMOTE present Bank. It may also be necessary to do a wake-up upon any power -up of the 1788A- R. During wake-up, the Comm indicators will show activity with units that respond to handshaking.
P age 22 P age 23 R/C Manual 3. 1788A-R HADRWARE REMOTE 3.2.6 T est T one Buttons These buttons serve the same purpose as those on a 1788A . Y ou can put up a -20dB or 0dB tone on any channel of the unit that is selected. Putting Up a T est T one While holding down either the -20dB or 0dB T one button, press any Channel Select button.
P age 24 P age 25 R/C Manual 3. 1788A-R HADRWARE REMOTE 3.2.7 Control/Display P anel This area of the 1788A-R’s front panel replicates the 1788A ’s local control and display panel. It gives you the exact look of the selected 1788A ’s function status lights and meters.
P age 24 P age 25 R/C Manual 3. 1788A-R HADRWARE REMOTE finished loading, the number will be updated in the left side of the window labeled “Last Sent”.
P age 26 P age 27 R/C Manual 3. 1788A-R HADRWARE REMOTE memory into whatever preset bin is showing in the right-hand window as long as it is not protected. While in Edit Mode you can select other unprotected preset bins before pressing Snapshot. Presets created in Edit Mode are in every way equal to live snapshots.
P age 26 P age 27 R/C Manual 3. 1788A-R HADRWARE REMOTE release. This transmits a dump to the other unit (the clone). The original unit will begin sending it’s parametric and label data to the receiving unit. When the transfer is complete, the clone will update itself to the new parameters and the panel indicators will align accordingly .
P age 28 P age 29 R/C Manual 3. 1788A-R HADRWARE REMOTE Refer to Section 2 of this manual for full coverage of applying MIDI control to the 1788A-R. 3.5.4 RJ-45 Ethernet Jack This is the exclusive portal for piping remote control to 1788A ’s. It must be connected to a proper 10 or 100 Base- T LAN structure that has a DHCP server or router .
P age 28 P age 29 R/C Manual 3. 1788A-R HADRWARE REMOTE internal power supply is designed to operate from all nominal power sources from 85 to 265 volts a.
P age 30 P age 31 R/C Manual 4. BUILDING A PROPER NETWORK Sometimes, depending on when the remote controller and preamplifiers received their IP addresses, it may be necessary to use the W ake-up function to get the controller attached to all preamps in its bank and clear all red lights.
P age 30 P age 31 R/C Manual 4. BUILDING A PROPER NETWORK 4. Building a Proper Network 4.1 ST ANDARD P ARTS Networks used for remotely controlling 1788A ’s are built from standard Ethernet components such as Routers, Hubs and Switches. Standard CAT5/6 Ethernet cabling is used throughout.
P age 32 if there are any fixed IP addresses on the LAN, the Router has to be programmed to avoid issuing them to other clients. In other words, there can be no IP address duplications on the LAN. The DHCP Server (or Router) must have enough IP numbers available to handle all DHCP clients on the LAN.
