Industrial 20" CRT Monitor Installing the 6157 Industrial Monitor 5 This section describes how to install the monitor.
Industrial 20" CRT Monitor • Determine the minimum and maximum ambient humidity for the monitor by consulting the specification sheets at the back of this manual. Ensure that the humidity of the ambient air will not exceed these limits. In very dry environments, static charges build up very readily. Proper grounding of the equipment through the AC power cord can help reduce the likelihood of static discharges, which may cause shocks and damage electronic components.
Industrial 20" CRT Monitor 7 Panel Mounting Guidelines Observe the following precautions before installing the unit in a panel: • Confirm that there is adequate space behind the panel. Remember to allow extra space (3 in. (76.2 mm) behind and 1 in. (25.4 mm) below and on each side) for air circulation. • Confirm that the cabinet is deep enough to accommodate the monitor's depth while providing rear clearance for airflow. A cabinet with depth of 23.11 in. (587 mm) is sufficient.
Industrial 20" CRT Monitor Mounting the 6157 Industrial Monitor in a Rack Due to the front panel size and stud pattern, the 6157 Industrial Monitor can be installed in an EIA 19” 9U panel standard rack. Refer to the following figure: Figure 2 Generic Rack Mounting Diagram Important: If you install the 6157 Industrial Monitor in a rack, you must ensure that the rack can support the weight of the monitor. You might need to install a support or shelf under the rear of the monitor to support the weight.
Industrial 20" CRT Monitor 9 Dimensions This section provides diagrams you need to follow to install the unit. Figure 3 6157 Industrial Monitor Dimensions Publication 6157-5.
Industrial 20" CRT Monitor Panel Mounting Procedure 1. Confirm that the shipping carton contains a package of 20 10-32 lock nuts and 20 flat washers. You will need 18 nuts and washers for installation. 2. Refer to the physical dimension drawing (Figure 3) and confirm that there is adequate space behind the panel. Remember to allow extra space for circulation and cabling. 3. Refer to the panel cutout drawing below for dimensions of the panel cutout and mounting hole locations. Cut and drill the panel.
Industrial 20" CRT Monitor 11 4. Carefully remove the monitor from its packaging. Avoid damaging the monitor gasket. Tip: It will be easier to install the monitor if you support it with a shelf or other support adjusted to the appropriate height. 5. Insert the monitor in the panel cutout from the front. Do not damage the threaded mounting studs as you position the monitor. 6. Secure the unit with the lock nuts and washers provided. Tighten evenly to 24 inch-pounds of torque.
Industrial 20" CRT Monitor Connecting the 6157 Industrial Monitor The rear panel of the 6157 Industrial Monitor has connectors for attaching cables to accomplish the following: • Connecting to a host video source (HD-15 VGA or BNC connectors) • Connecting to a host touchscreen control port (DB-9 connector) (optional) • Connecting to AC power Note: Some connectors on your monitor may differ from the following figure.
Industrial 20" CRT Monitor 13 Connecting the Video Source The video connection to the host is made through a HD-15 (female) connector or through BNC input connectors. To establish a signal using the HD-15 connector: Note: For more information on using an HD-15 video cable to connect to the host computer, refer to Appendix B (Page 28). 1. Obtain a shielded, properly terminated video cable of length as short as possible.
Industrial 20" CRT Monitor Connecting the Configuration Port The 6157 Industrial Monitor is equipped for remote control by the host computer. You can use the serial configuration port to provide bidirectional communication between the monitor and the host computer. The host computer can send commands to the monitor requesting information about the monitor’s status or to adjust monitor operating conditions. Note: Please contact Technical Support for more information on using the configuration port.
Industrial 20" CRT Monitor 15 To connect the touchscreen: 1. For units with the touchscreen option, make sure you have one of the optional serial cables. 2. Connect one end of the touchscreen serial cable to the T/S port connector on the rear of the monitor. 3. Connect the other end to any serial communications port on the host computer. 4. Tighten the captive screws on the cable connector to secure it.
Industrial 20" CRT Monitor Operating the 6157 Industrial Monitor This section describes how to operate the 6157 Industrial Monitor. Controls The following is a summary of the controls and indicators on the membrane keypad on the 6157 Industrial Monitor: Figure 6 Monitor-Resident Controls Note: The number of controls supported by the monitor may vary depending on the monitor type or customer-specified options.
Industrial 20" CRT Monitor 17 Manual Degauss The monitor is equipped with an automatic degaussing system to remove residual magnetism from the CRT’s shadow mask at power-up. Degaussing helps keep the screen free of any color impurities which might otherwise result from magnetism picked up by the shadow mask from the earth’s magnetic field when the monitor is moved. In addition, a degauss push button is provided on the control panel.
Industrial 20" CRT Monitor 4. Use the left arrow button to lower the brightness until the dark gray colors change back to black. This is the optimal brightness setting given the current lighting conditions 5. Press the Select Mode button until the status LED indicator below the Contrast icon is lit. 6. Use the left and right arrow buttons to change the value for the contrast control to achieve the appropriate level of intensity in the image.
Industrial 20" CRT Monitor 19 To change raster rotation: 1. Press the Select Mode button until the status LED indicator below the raster rotation icon is lit. 2. Use the left and right arrow buttons to adjust the rotation. Important: The raster rotation control cannot correct for the effects of external AC fields such as those produced by large motors, generators and transformers. Such effects often take the form of display jitter.
Industrial 20" CRT Monitor Routine Maintenance Cleaning Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to avoid scratching it with accumulated grit. Note: The solvent should be applied only to the cloth, and not directly on the monitor screen. Do not use paper products as they may scratch the surface.
Industrial 20" CRT Monitor 21 Fuse Replacement The Bulletin 6157 Industrial Monitor is equipped with two AC line fuses housed in the IEC connector (2.5A 250V). To access the fuses, you must remove the rear cover of the unit. ATTENTION: Fuse replacement requires work in areas that can present dangerous voltages. Always disconnect the AC power cord and wait one minute before attempting fuse replacement. Replace the rear cover before restoring power to the monitor. To replace the fuses: 1.
Industrial 20" CRT Monitor 4. Remove each fuse by inserting the tip of a small flat-bladed screwdriver between the fuse clip and the metal end cap of the fuse and gently prying the fuse out of its clip. 5. Replace each fuse as required with a 5ST Slo-Blo type fuse rated at 2.5A, 250VAC. 6. After replacing each fuse in its clip holder, reinstall the plastic cover over the fuses, reinstall the rear panel of the monitor, and reconnect the AC power cord.
