Module Installation 1. Turn off all power to the unit. 2. Make all necessary jumper selections. 3. Position module in front of any desired module bay opening, making sure that the module is right-side up. 4. Slide module onto card guide rails. Make sure that both the top and bottom guides are engaged. 5. Push the module into the bay until the faceplate contacts the unit’s chassis. 6. Use the two screws included to secure the module to the unit.

Controls and Connectors Gain (Input) Level (Output) Provides control over the level of input signal. Provides control over the level of output signal. RJ11 Connection This connector contains the output signal and a set of normally open relay contacts. It acts similar to telephone systems’ page ports and facilitates interfacing to paging systems with override capabilities (PCM2000, ZPM3). Signal Output Transformer-balanced, low-impedance (8-ohm) line-level output.

Jumper Selections Impedance Selector This module can be set for two different input impedances. When connecting to a 600-ohm source, it is desirable to have a 600-ohm matching input impedance. For typical source equipment, use 10kohm setting. Input Muting This module’s input can remain continuously active or be muted by other modules. When muting is enabled, the input is permanently set to the lowest priority level.

Jumper Selections, cont. Relay Priority Level The relay setting determines what priority level and above will cause the relay to energize. Since this module’s relay must receive a mute signal from a higher priority module to change states, it is only possible to use the three lower priority levels (2, 3, 4). Priority Level 1 (highest) is not applicable. Output Gating The output signal can be available continuously or available only when the relay priority level setting has been met or exceeded.

Input Wiring Balanced Connection Use this wiring when the external equipment supplies a balanced, 3-wire signal. Connect the shield wire of the external signal to the ground terminal of the external equipment and to the ground terminal of the RIO1S. If the "+" signal lead can be identified, connect it to the plus "+" terminal of the RIO1S. If the external equipment polarity cannot be identified, connect either of the hot leads to the plus "+" terminal.

Output Wiring Balanced Connection Use this wiring when the external equipment requires a balanced, 3-wire signal. Connect the shield wire to the ground terminal of the external equipment and to the ground terminal of the RIO1S. If the "+" signal lead from the external equipment can be identified, connect it to the plus "+" terminal of the RIO1S. If the external equipment polarity cannot be identified, connect either of the hot leads to the plus "+" terminal.
