Specifications

3.2.1 Mechanical Installation
The DAI-2 is designed to be mounted in a standard 19 inch equipment rack. The system generates little heat and can
be mounted in just about any convenient location. The DAI-2 should be mounted at a location which is convenient to
the equipment that will be connected to it.

3.2.2 DAI-2 Relay Panel Interconnect
The DAI-2 should be connected to its relay panel with the 20 conductor flat (ribbon) cable. This cable is supplied with
the system and is terminated with one connector at each end. One end of the flat cable connects to the rear of the
DAI-2 control unit at the connector labeled “Relay Panel” (see Figure 3.2). This connector is keyed to fit in one
direction and will be held secure by latches when fully inserted.
Figure 3.2; Rear panel connectors
On the relay panel, the tab on the flat cable connector should line up with the connector outline around J1 on the relay
panel (see Figure 3.3). This connector has no outer shell and is not keyed so make sure that the connector is
properly oriented and aligned with all pins before applying pressure.
3.2.3 Telephone Line Connection
The DAI-2 should be connected to a standard (POTS) telephone line with the modular (RJ11C) jack on the rear panel
labeled "Line". A telephone cable is supplied with the DAI-2 for this purpose.
