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. Details of proper network construction are covered in Section 4 of this manual.

3.6 INSTALLATION

The Model 1788A-R occupies three rack spaces (135mm or 5-1/4 inches) of a standard EIA equipment rack.

3.6.1 Interface Cable

The Power Unit and Control Unit are connected together through a standard 25-pin D- Sub straight-throughprinter cable. The length of this cable should be less than 6.5 feet (2 meters) to prevent power loss. Use only shielded cables.

3.6.2 Rack Mounting

When rack mounting, use appropriate cushioned rack screws with the supplied rack ear adapters. Never restrict air flow through the device’s vents. When installing the units into a rack, distribute the units evenly. Otherwise, hazardous conditions may be created by an uneven weight distribution. Connect the unit only to a properly rated supply circuit. Reliable earthing (grounding) of rack mounted equipment should be maintained. Try not to position the 1788A-R directly above devices that generate excessive heat such as power amplifiers (unless adequately ventilated).

Figure 3-5. Rack Mounted Configuration

The Power Unit should be bolted directly to the back of the Control Unit using furnished UNC 6-32 x 1/4 inch screws. Both units’ 25-pin D-Sub connectors should be connected together using the supplied short-length cable.

3.6.3 Desktop Mounting

The Power Unit may be remotely located to permit the Control Unit to lay flat on a desktop. For this purpose, a second D-Sub side-facing connector is provided for flat cable entry. It’s a good idea to place non-slip adhesive rubber feet on the Control Unit’s under- side. The Power unit may be mounted under the desk or on a sidewall. Make sure not to block the air vents.

3.6.4 AC Line Connection & Power

Use only a power cord that carries approvals for use in your location. The 1788A-R’s
