1 Logic Control in Tesira Device Logic I/O Operation Mute Control 1 logic input per audio channel, up to 16 channels (56 ganged) Logic input 1 causes audio channel to mute. Logic input 0 causes audio channel to un-mute. Level Inc/Dec 1 logic input for level up (+) on each audio channel. 1 logic input for level down (-) on each audio channel. Up to 32 audio channels (64 ganged) Logic 1 input to (+) causes level to ramp up. Logic 1 input to (-) causes level to ramp down. Optional: Disable ramping Transition from logic 0 to 1 on (+) causes audio to increment up. Transition from logic 0 to 1 on (-) causes audio to increment down. Remote Preset 1 logic input per preset, up to 10 presets Transition from logic 0 to logic 1 triggers preset to recall TI Dialer 19 logic inputs and 1 logic output Transition from logic 0 to logic 1 on input 1 to 16 causes the associated speed dial number to be dialed. Transition from logic 0 to logic 1 on Rdl input causes the last number to be redialed. VoIP Dialer 34 logic inputs (17 for each line) Transition from logic 0 to logic 1 on input 1-x to 16- x causes the associated speed dial number in the corresponding line to be dialed. Transition from logic 0 to logic 1 on Rdl-x input causes the last number to be redialed in the corresponding line. BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 1 of 9

2 Gating Auto Mixer 1 per input channel, up to 256 channels Logic output normally Logic 0 Switches to Logic 1 as long as corresponding input channel is gated on. Optional: Behavior of may be inverted in control dialog. Room Combiner 1 logic input per partition plus 5 source selection inputs (4 sources + Off) per room, up to 32 rooms (58 partitions) 1 per partition plus 5 source selection outputs (4 sources + Off) per room, up to 32 rooms (58 partitions) Logic 0 on partition input causes partition to remain open. Logic 1 on partition input causes partition to remain closed Transition from logic 0 to 1 on source inputs selects the corresponding audio source (or Off) for the corresponding room Logic 0 on partition output indicates partition is open Logic 1 on partition output indicates partition is closed Logic 1 on any source selection output indicates that source (or Off) is selected for that room Source Selection Ducker 1 Logic input per channel, up to 32 channels 1 Logic output per channel, up to 32 channels 1 logic input and 1 logic output Transition from logic 0 to 1 on logic inputs selects the corresponding audio source Logic outputs normally logic 0. Logic 1 on logic output indicates corresponding audio source is selected 1 on logic input causes program audio to duck and to be 1. 0 causes program to un-duck. Audio signal exceeding threshold on sense input causes to be 1. Audio signal below threshold causes to be 0. Optional: Behavior of logic control may be inverted in control dialog.

3 AGC 1 A logic 1 indicates the AGC is applying or reducing gain In Speech Mode, a logic 1 indicates Speech is being detected DTMF Decode 17 s Logic outputs 1 thru D pulse high for 250msec when the corresponding DTMF tone is detected. Logic output Any pulses high for 250msec when any DTMF tone is detected. BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 3 of 9

4 TI Control/Status 2 logic inputs and 10 logic outputs Logic 1 on HS input picks up the line or takes off hook. Logic 0 causes the line to hang up or Put back on hook Transition from logic 0 to logic 1 on HF input causes a hook flash. Logic 1 on RI = line is ringing Logic 0 on RS = line is not ringing Logic 1 on DIP = Dialing in progress Logic 0 on DIP = Not dialing Logic 1 on HSS = Off hook Logic 0 on HSS = On hook Logic 1 on DTD = Dial tone detected Logic 0 on DTD = No dial tone Logic 1 on BTD = Busy tone detected Logic 0 on BTD = Busy tone not detected Logic 1 on RTD = Ring tone detected Logic 0 on RTD = No ring tone detected Logic 1 on LR = Line ready Logic 0 on LR = Line not ready Logic 1 on LIU = Line in use Logic 0 on LIU = Line not in use Logic 1 on LI = Line intrusion Logic 0 on LI = No line intrusion Logic 1 on LF = Line fault detected Logic 0 on LF = No line faults BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 4 of 9

5 VoIP Control/Status 24 logic inputs (two per appearance per line) and 26 s (two per appearance per line plus 2 per line) Transition from 0 to 1 on ANS x.y answers the call on appearance x line y Transition from 0 to 1 on END x.y ends the call on appearance x line y Logic 1 on RI x.y indicates appearance x on line y is ringing Logic 1 on LIU x.y indicates appearance x on line y is in use Logic 1 on LR1 (LR2) = Line 1 (2) in line ready mode Logic 0 on LR1 (LR2) = Line 1 (2) in not ready mode Network Command String 1 logic input per command string, up to 32 Transition from logic 0 to 1 triggers command string to output network port. Serial Command String 1 logic input per command string, up to 32 Transition from logic 0 to 1 triggers command string to output serial port. Logic Input Up to 16 channels Open on logic input = Logic 1 Closure on logic input= Logic 0 Optional: Behavior of logic control may be inverted in control dialog.

6 In Logic mode Logic 1 on = open Logic 0 on logic input =closure Up to 16 channels In LED Driver mode Logic 1 on = Up to 24V/500mA Logic 0 on logic input = Short to ground Logic Output/LED Driver Optional: Behavior of logic control may be inverted in control dialog. Logic Delay 1 logic input and 1 logic output per delay, up to 32 1 on logic input must be present for specified ON time before changes to 1. 0 on logic input must be preset for specified OFF time before changes to 0. OR Gate 1 at either or both logic inputs causes a 1 at logic output. Otherwise, is AND Gate 1 at both inputs causes a 1 at. Otherwise, is BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 6 of 9

7 NOT Gate 1 logic input and 1 logic output per gate, up to 32 1 at logic input causes a 0 at. 0 at logic input causes a 1 at. Input Output NOR Gate 0 at both logic inputs causes a 1 at. Otherwise, is 0. (Logically the same as an OR gate followed by a NOT gate.) NAND Gate 1 at both logic inputs causes a 0 at. Otherwise, is 1. (Logically the same as an AND gate followed by a NOT gate.) BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 7 of 9

8 XOR Gate 1 at either but not both logic inputs causes a 1 at. Otherwise, is Flip Flop Gate 1 logic input and 1 logic output per gate, up to 32 0 to 1 transition at logic input causes to toggle from its present state to the opposite state. Logic Meter 1 logic input per meter, up to 32 Logic 1 on input node turns corresponding indicator on Logic 0 on input node turns corresponding indicator off Logic State 1 per state, up to 32 Setting a State On causes the corresponding logic output to be 1. Setting the State Off causes the corresponding to be 0 Fan-In OP Pulse Transition from logic 0 to logic 1 on any of the inputs generates a 150ms logic pulse on the output Signal Present Meter 1 logic input per meter, up to 32 Audio signal exceeding threshold on sense input causes to be 1. Audio signal below threshold causes to be 0. BIAMP SYSTEMS TECHNICAL SUPPORT GROUP Page 8 of 9
