[. . . ] The program change commands call up the internal memories, chase or "OFF" (see Memory menu 4. 3). 4. 4. 4 MIDI CHANNEL The MIDI channel can be selected between 1. . . 16. 4. 4. 5 CLEAR CURVES (set curves to linear, default) Deletes both free programmable control curves (set to linear) (see 4. 4. 8). Therefore the cursor is set on this line, the right button is pressed and the encoder turned simultaneously. Be careful using this function, because it may be hard work to reprogram the curves. 4. 4. 6 USER MODE (cut down the operation of the dimmer) With this function the dimmer function can be cut down in 3 steps: -SUPER -NORM "Supervisor" means, that all functions can be used. "Normal User" means, that in the Channel Menu only the DMX address can be programmed. This mode should be used, when the dimmer must be protected but the test function must remain usable and the DMX address must be programmable. The dimmer is completely locked and can not be operated with the buttons or encoder. The middle button is an exception because it allows the entry into the Setup Menu by pressing it for 5 seconds. Comment: The DMX as well as the analogue input works normally as before. -LOCK 4. 4. 7 DELETE ALL (set all to default) "Delete All" deletes all memories, chases, DMX addresses, curves, etc. The DMX address will be set to "1" and the "Block" Mode is activated. Be careful in using this function, because it may be hard work to reprogram all functions. 10 MA Lighting Technology GmbH . and 4. 4. 9 CURVE USER (User definable control curves) Here the setup menu for the control curve 1 and 2 can be activated. Individual brightness curves can be programmed, just as necessary for a lamp. In the curve menu the encoder changes the position of the cursor in the x-axis (input); when the right button is pressed, the y-axis (output) can be modified. Y X Example 1 (linear): Here the connection between input (lighting control desk) and output (lamp) is linear and 1:1. Example 2 (logarithmic): The output (lamp) reacts even at low input values. Example 3 (exponential): The output (lamp) reacts very little to small inputs, but all the more when the input is higher. Example 4: Lamp does not react till input is at 50 % , but in this case reacts linear. Example 5: Lamp is controlled inversely. If the input is 0 % , the Lamp is activated to 100 %, if input is 100 %, the lamp is off (0%). 4. 4. 10. (activate phase angle correction) Usually this control parameter is set to "ON". The normal non-linearity, produced by the SRC´s phase angle control, is thereby compensated. This function should only be deactivated ("NO"), when this correction is made internally by the control desk (e. g. MASTER/SLAVE (coupling of dimmers) For coupling several dimmers, the master and slave part can be defined. For this function a 5 wire DIN cable must be used; MIDI cables often have only 3 wires! [. . . ] When the EPROM is changed, all pins must fit into the socket before the EPROM is pressed into the socket. When the cover is mounted again, please be careful not to damage the encoder. Furthermore make sure the buttons can be moved easily. remove black Phillips screws (on every side 7 pcs. , at the bottom 2 pcs. , at rear 8 pcs. ) 1. Don´t remove these two silver screws (2 pcs.
