6. Never use a Y connector to split the link To split the serial link into branches use a splitter such as the Martin 4 Channel Opto Isolated RS 485 Splitter Amplifier Do not overload the link Up to 32 devices may be connected on a serial link Terminate the link by installing a termination plug in the output socket of the last fixture on the link The termination plug which is simply a male XLR connector with a 120 ohm 0 25 watt resistor soldered between pins 2 and 3 soaks up the control signal so it does not reflect back down the link and cause interference If a splitter is used terminate each branch of the link CONTROL PANEL You set the address and personalities read out data and execute service utilities from the control panel Settings can also be changed remotely via the serial link with the Martin MP 2 uploader See also the control menu table starting on page 41 Menu navigation The DMX address and any error messages are displayed after the fixture resets To enter the menu press menu Use the up and down keys to move within the menu To select a function or submenu press enter To escape a function or menu press menu DMX Mode selection The fixture has two DMX operating modes 16 bit and 16 bit Extended 16 bit Extended mode uses 17 DMX channels three more than the 14 DMX channels than standard 16 bit mode requires 16 bit Extended mode provides more precise control of the dimmer color and focus setti
