emview-19t/d (User's Manual) Introduction 1-5 1 Introduction Janz Automationssysteme AG s em[view] systems are an additional development. These HMI systems and industrial display solutions are a combination of the familiar Janz empc systems with a wide range of LCDs, with or without touch-screen. Starting from 6.4, the LCDs can be combined with empc-a400 or empc-m as a complete HMI solution with smallest dimensions and power dissipation. em[view]s are also available without touch-screen. The em[view]-19t/d is a display only solution. If a touch-screen is not needed contact Janz Automationssysteme AG for further information. 1.1 Features Touch screen linked by RS232 or USB Wake On Touch (with RS232, only) DVI and VGA connectors Small housing size 14 32 V DC power supply Fanless cooling concept Protection rating of the front is IP65 Fast und easy mounting High grade aluminium front Customizable design of the front panel Very flat front panel design (only 4 mm) 1.2 Functional Overview em[view]s are normally delivered with a touch-screen. To use the touch-screen the em[view]-19t/d must be connected to a standard RS232 or USB port of a computer system e.g. an empc and a driver must be installed at the host. The control of the resistive touch-screen is realized through a PenMount DMC9000. The resistive touch-screen is realized through a 2.1mm thick glass panel with resistive surface. The PenMount controller is linked to the RS232 port and USB port. If the USB port is used, the serial port is deactivated. The power must be supplied by an external power supply. This power supply must be capable to provide enough power for the em[view]-19t/d. Please refer to the technical specifications section for more information. Rev. 1.0 Janz Automationssysteme AG

emview-19t/d (User's Manual) Installation 2-7 2 Installation When opening the shipping package of the em[view], the contents of the package should be checked immediately. The em[view] is delivered in a configured state, but the configurations can be adjusted by the user as well. To adjust the em[view]s configuration, an OSD (On Screen Display) is installed and controllable by buttons at the backside. The package also contains a terminal plug for the power connector. The em[view] needs a power source in between 14 to 30V DC for operation. The installation of this equipment is allowed for qualified service personnel only. Before connecting the DC main supply, the protective bonding conductor (PE) must be attached to prevent hazardous voltage. Auxiliary existing rules for installation of electrical equipment must be attended to. 2.1 Dimensions and mounting information E B D C A Figure 3: em[view] measures The needed cut-out measures are given by A and B. The overall front panel dimensions are denoted with C and D. E is the depth of the case.

2-10 emview-19t/d (User's Manual) Installation Pin Assignment Output 1 NC 2 TxD 3 RxD 4 NC 5 GND 6 NC 7 RTS 8 NC 9 RI Table 3: SUB-D 9 Pin assignment The em[view]-19t/d provides a ring indicator (RI) signal for waking up the host PC. To use this feature the host must provide Wake On Ring (also PowerUp on Modem ) and this option must be activated in the BIOS. The length of serial cable must not exceed 10 m. 2.3.3 Universal serial bus - USB To connect the touch-screen to a host computer the USB can be used, too. The connector is USB Type B, so a standard USB Type A to Type B cable can be used to connect the touch-screen with the host. The length of USB cable must not exceed 5 m. 2.3.4 Analogue Video - VGA There are two ways to apply video data. One of them is an analogue video signal over the VGA connector (High density 15 pin female SUB-D). Analogue resolutions to SXGA (1280x1024) at 75 MHz or UXGA (1600x1200) at 60 MHz are support. A 10 m VGA cable is tested with the em[view]-19t/d. 2.3.5 Digital video - DVI As noticed earlier there is a second way to apply video data, the digital input DVI. The reliable DVI port is operating up to 165 MHz (UXGA at 60 MHz), thus it can be connected to all compliant digital DVI transmitters. The length of the DVI-D cable must not exceed 10 m. The best picture results are obtained by setting the native resolution. The native resolution of the display is 1280 x 1024 (SXGA). 2.3.6 Display The panel is build as a thin film transistor liquid crystal display TFT-LCD with a diagonal screen of 19 and up to 16M colours.
