| DMX710 DMX512 Transmitter with 6/8/12 digital or analoge inputs FEATURES * * * * * * 5V SUPPLY VOLTAGE TRANSMIT DMX512 SIGNAL CASCADEABLE FOR MORE INPUTS UP TO 12 DIGITAL INPUTS UP TO 6 ANALOGE INPUTS PACKAGE: DIL28S DESCRIPTION The DMX710 is an DMX512 transmitter with digital inputs. The values of the output signal are 0 or 255 in digital mode and 0 - 255 in analoge mode, dependent on the input signal. With the BLACKOUT input it is possible to set all DMX output channels to 0. To combine some DMX710 chips, connect the DMX output with the DTC input (DMX transmitter chain) from the next chip. More informations about the DTC you can find in the separate document.

A low level on this pin for more then 50ns will generate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset DTC-SIGNAL Input for the DMX Transmitter Chain (DTC). If not used, this pin must connect to GND. DMX-SIGNAL Output for the DMX512 signal POWER This is the power supply GROUND 0V reference XTAL0 Input from the inverting oscillator amplifier XTAL1 Output from the inverting oscillator amplifier STATUS LED LED output. This pin can sink 20mA to drive a LED. DIGITAL/ANALOG INPUT 1 Input for the DMX value 1 DIGITAL/ANALOG INPUT 2 Input for the DMX value 2 DIGITAL/ANALOG INPUT 3 Input for the DMX value 3 DIGITAL/ANALOG INPUT 4 Input for the DMX value 4 DIGITAL/ANALOG INPUT 5 Input for the DMX value 5 DIGITAL/ANALOG INPUT 6 Input for the DMX value 6 DIGITAL INPUT 7 Input for the DMX value 7 DIGITAL INPUT 8 Input for the DMX value 8 DIGITAL INPUT 9 Input for the DMX value 9 DIGITAL INPUT 10 Input for the DMX value 10 DIGITAL INPUT 11 Input for the DMX value 11 DIGITAL INPUT 12 Input for the DMX value 12 BLACKOUT Input to set all DMX-Outputs to 0 MODE 0 ; MODE 1 Select number of inputs (11: 6 channels / 10: 8 channels / 01: 12 channels ) FIRST CHANNELS ANALOGE INPUTS Input to set IN1-6 to analoge inputs (Hanalog/Ldigital) INVERT INPUTS Input to select the polarity of the digital inputs 1-12 and BLACKOUT DTC IN 2 I DMX OUT VCC GND X0 X1 LED IN 1 IN 2 IN 3 IN 4 IN 5 IN 6 IN 7 IN 8 IN 9 IN 10 IN 11 IN 12 BLACKOUT MODE 0,1 3 7;20;21 8;22 9 10 4 23 24 25 26 27 28 14 15 16 17 18 19 5 11;12 O I I I O O IN IN IN IN IN IN IN IN IN IN IN IN IN IN FCAI INV INPUT 6 13 IN IN (c) 2006 Markus Siwek WWW.DMX4ALL.DE 2 DMX710 ELECTRICAL CHARACTERISTICS Parameter VCC ICC VIH1 VIH2 VIL fOSZ Description Operating Supply Voltage Operating Sypply Current Input High Voltage Input High Voltage Input Low Voltage Oszillator Frequency Min Typ Max 3,5 5 5,5 0,6 0,9 -0,5 8 Units Conditions V mA VCC+0,5 V VCC+0,5 V RESET Pin 0,2 V MHz Absolute Maximum Ratings Operating Temperature Storage Temperature Voltage on any Pin except RESET with respect to Ground Voltage on RESET with respect to Ground Maximum Operating Voltage DC Current per I/O Pin DC Current VCC and GND Pins -55C to +125 -65C to +150C -0.5V to VCC+0.5V -0.5V to +13.0V 6.0V 40.0 mA 200.0 mA Error-Codes The LED display internal errors. The error code is the number of flashes between 2 long times the LED is off. Error-Code 3 Description No valid DTC signal is recognize at the DTC INPUT. (c) 2005 Markus Siwek WWW.DMX4ALL.DE 3 DMX710 DEVICE CONFIGURATION EXAMPELS Oscilator Configurations C1 X0 C2 Q1 X1 GND This example illustrates how to use the DMX710 with a 8MHz crystal. The value of the capacitors should be in the range of 12-33pF. Digital And Analog Input Configuration VCC DIGITAL IN ANALOG IN Some of the pins of the DMX710 can be used as digital or analog inputs. In the digital mode you have to connect a switch to GND. The analoge mode permit a signal from GND to VCC. DMX Interface Configuration 8Mhz Oszillator X0 DTC IN DMX OUT DTC IN X0 DMX OUT DMX710 DMX710 SN75176 The DMX710 is cascadeable, as the DMX exit is connected with the DTC entrance of the next component. The last DMX exit goes to a line driver. It is possible to use one oszillator for all DMX710.
