Press "Press to Start" on the TEC-X 2000 and both screens come down, both Epson L260F projectors turn on, and both switch to HDMI 1 at the 34 s mark, all from logic inside one TesiraFORTÉ X 400. This page traces that chain and every other one in the v1_0_3 Tesira design, as decoded from the file: the 47 buttons, the projectors and screens, the mic levels, and the check that asks the Shure ULXD4D which transmitters are in use.
Each lane shows Projector 1 and Projector 2 together; the P1 and P2 blocks are wired identically. Lanes 4, 6 and 9 run right to left: they carry replies and status back into the design.
The Splash page's single button starts RmPowerOn and opens Home. The Confirm page's Power Off starts RmPowerOff and returns to Splash. Each is a one-step Logic Sequence (500 ms on, 500 ms off) whose output goes through a Fan-In OR Pulse to start both projectors' sequences at once.
Power Up Sequence: step 1 lowers the screen at once, step 2 sends PWR ON 1 s in, step 3 sends SOURCE 30 (HDMI 1) 34 s in, after the L260F's 30 s warm-up (steps of 500/500, 500/32,500 and 500/500 ms). Power Off Sequence: step 1 raises the screen, step 2 sends PWR OFF 1 s in, step 3 sends it again 36.5 s in (500/500, 500/35,000, 500/500 ms). Steps 2 and 3 meet at an OR Gate, because the L260F ignores PWR OFF during warm-up. A custom block of two Fan-In OR Pulses turns each step into a single command trigger. The projector pages' Power button is a latch: showing "Power Off" it starts the Up sequence; showing "Power On" it starts the Off sequence.
The init Logic State is saved on, so at boot it fires a Fan-In OR Pulse. That pulse also triggers the ULXD4D query (lane 8), and 250 ms later starts both Polling Sequences. Each has five steps of 500 ms on and 3,000 ms off and repeats indefinitely, so a projector is asked one question every 3.5 s and gets a full pass every 17.5 s. On connect, each projector block first sends the Epson handshake ESC/VP.net from its Connection Sequence.
Each reply that matches a pattern pulses a logic output into one of five Logic Selectors: POWER (standby, normal, warm, cool, abnormal), A/V MUTE, FREEZE, SOURCE (eleven inputs) and ERROR. Their outputs light a 19-indicator Logic Meter per projector. A PWR=05 (abnormal) reply also sends ERR? straight away. In standby the L260F answers only the power query, so the mute, freeze and source indicators hold their last values.
P1Screen is a three-state Logic Selector: 1 Down, 2 Up, 3 idle. Screen Down sets state 1 and Screen Up sets state 2; the power sequences drive inputs 1 and 2 the same way. The Down output pulses Logic Output 1 channel 1, and the Up output pulses channel 2.
A Logic Selector only pulses when its state changes, so a second press of the same button would do nothing. After every move, an OR feeds the "Logic VIA" custom block: the logic drives a mute on a tone, a signal-present meter turns the tone back into logic, and a 250 ms Logic Delay sets the selector to state 3 (idle). The same pulses also set a Screen State selector, which lights the Screen Status meter.
Both are two-state Logic Selectors: state 1 Off, state 2 On. The button sends the opposite of what it shows, so "Video Mute Off" sets state 2 and sends MUTE ON. If the selector is already in that state nothing is sent.
CommandString15 sends < GET 0 TX_TYPE > three ways: from its Connection Sequence when it connects, from the boot pulse on its INIT input, and whenever the receiver reports TX_MUTE_BUTTON_STATUS RELEASED (response 9 sends command 1). So releasing a transmitter's mute button re-checks both channels.
Patterns ?LXD2, ?LXD1, ?LXD6 and ?LXD8 match handheld, bodypack, boundary and gooseneck transmitters; the ? wildcard also covers QLX-D. Outputs 1 to 4 drive channel 1's Source Selector and outputs 5 to 8 drive channel 2's, picking HH - 7, Lav - 7, Boundary - 7 or Goose - 7. A transmitter that matches nothing leaves the last preset in place. An 8-channel Logic Meter shows the current choice.
Each ramp (Wlx1Ramp, Wlx2Ramp, MicRamp, USBRamp) is a two-channel Logic State. Volume Up sets channel 1 on press and hold and clears it on release; Volume Down does the same on channel 2. Channel 1 drives the Level block's +1 input and channel 2 its −1 input, so the level moves only while a button is held. Mute writes the Level block's mute attribute directly, with no logic in between.
Arrows are the Page Flip links. Every page below Home also has a Back or Home button that returns one level up. Confirm's Power Off ends at Splash; its Go Back returns to Home.
