DMXPathfinder LR Introduction INTRODUCTION WELCOME TO THE WORLD OF DMXPATHFINDER! This Installation Guide is intended to walk you through a typical installation. In preparing the User Guide, it has been assumed that you are reasonably familiar with the DMX512 and the various wiring methods associated with RS422/485 based protocols. Installing and configuring the PC software is covered in detail in the Installation and User guide.
DMXPathfinder LR Installation & Assembly Chapter 1: Installation and Assembly SUMMARY This section describes how to correctly assemble the DMXPathfinder LR hardware into an equipment rack and connect permanently installed external wiring. To ensure a trouble-free installation, you should follow this sequence: 1. 2. 3. 4. 5. 6. 7. 8. 9.
DMXPathfinder LR Installation & Assembly the same rack, allow for at least a 1U vent panel at the top and bottom of the rack. Power Requirements -- A single phase power source (50 or 60Hz, 100240VAC, at 0.1A per Input Module and 0.25A per Output Module) must be provided to the DMXPathfinder LR equipment rack. It is recommended that no more than ten I/O modules be connected to one power circuit due to the startup current requirements of their switch-mode power supplies.
DMXPathfinder LR Installation & Assembly Modules and 4U Output Modules to be installed, then add at least 2U for vent panels and allowance for power bars, connector panels or other accessories if required. Louvered, locking front and rear doors are recommended. Locate the rack such that at least 3 feet of clearance is allowed at the front, 2 feet at the back, and sufficient clearance at one side (preferably the left) to permit service access to the internal cable connections.
DMXPathfinder LR Installation & Assembly boards mount directly to the rear of each output module using five 6-32 standoffs and screws. They electrically connect to each Output Module with eight 25-pin D-style connectors, therefore a certain amount of force is required to mate the two parts. Ensure that all 8 connectors are fully mated and that the board is resting on the standoffs before installing the five screws.
DMXPathfinder LR Installation & Assembly each module, and use 8-32 screws to attach the rack mount ears to the sides of each Input and Output Module. If P2020 type termination boards are to be used, mate them to each Output Module and fasten with 5 x 6-32 screws. Using one power cord, power up each Input and Output Module one at a time and verify that the main power LEDs illuminate. Remove the four adhesive rubber feet from the bottom of each module.

DMXPathfinder LR Installation & Assembly Remember that for systems with only one input module, only the CABLE A jacks need ribbon cable jumpers and the bus terminator installed. I/O C ABLE CONNECTION Strip back about 3 inches (8cm) of cable jacket and braid shield from each input or output cable. Apply a 2.5" (6.5cm) piece of 1/16" heat shrink to the drain wire and a 1" (2.5cm) piece of 3/8" heat shrink over the exposed braid ends where each cable was stripped.
DMXPathfinder LR Installation & Assembly PC-COM C ABLE CONNECTION Each Output Module is provided with an 8-position rear-mounted terminal block for connection to the system’s personal computer. Two separate ports are provided: an RS232 port and an RS485 port. There is also a 10VDC phantom power supply available for powering an optional RS232/485 converter.
DMXPathfinder LR Installation & Assembly Pin 5 – Power & Signal Common (connect to “COM” terminal) Pin 6 – Data Set Ready Pin 7 – Request to Send Pin 8 – Clear to Send Pin 9 – Ring Indicate Only pins 2, 3 and 5 are required to connect for RS232 communications. If the RS232/485 converter is to be used, it is strongly recommended that a 3pair or 4-pair RS422/485 rated twisted pair data cable is used for the connection to the DMXPathfinder LR. Category-5 UTP cable works well.
DMXPathfinder LR Installation & Assembly T ESTING THE INSTALLATION Once all connections are made and inspected for errors, you can power up the DMXPathfinder LR modules in the equipment rack. With no DMX source signals present, all eight red Isolated Power LEDs on the face of each Input Module should be illuminated. On each Output Module, the green Processor OK and Main 5V Power LEDs should be illuminated. If, in addition, the green Crosspoint OK LED is on, this does not indicate a problem.
DMXPathfinder LR Maintenance & Testing Chapter 2: Maintenance & Testing CARD REPLACEMENT Should a defective component be found in an Output Module or other module during troubleshooting, it is best to replace the suspected defective circuit card with a spare unit and re-test. Powering down the entire DMXPathfinder, or at least the specific module, is recommended before removing or inserting cards.
DMXPathfinder LR Maintenance & Testing Tests using instrumentation will be performed where anomalies have developed in the system that cannot be isolated with standard troubleshooting procedures. Additionally, testing can establish minimum network performance where non-DMX512 control equipment is to be connected to the system. Fluke 650 Cable Meter -- Please refer to the manufacturer's user's manual for detailed instructions and theory before attempting to use this instrument.
DMXPathfinder LR Maintenance & Testing .2 Frequency Generator -- for testing crosspoint matrix and opto-repeater high-speed performance. Useful for evaluating whether other systems with higher data rates can be used in the network. .3 Digital Volt/Ohm Meter -- a general purpose tool for checking continuity, termination resistor values and power supplies.
DMXPathfinder LR Maintenance & Testing proves to be good, test the DMX cable installation for open or shorted lines using the DMXQConnect loopback test diagnostic (see Chapter 5). A similar test can be done for input cabling. If the above tests yield passing results and the problem persists, it may be necessary to use the Fluke LAN Cable Meter to do a high-frequency analysis of the suspect cable runs.
