6 MAP450D A power line filter installed at the AC input to the OIT power supply is highly recommended as a safeguard against conducted RF noise, which is often present on factory power lines. The wires connecting the output of the power line filter to the power supply should be kept as short as possible to minimize any additional noise pickup. The case of the power line filter should be connected to a quiet earth ground. The power line filter should have a current rating of at least three amps

The 3-wire configuration has both transmit and receive on the same pair of wires plus a signal common. The 5-wire configuration has differential signal pairs for transmit and receive plus a signal common. In both configurations the signal pairs must be twisted and surrounded by an overall shield.

INSTALLATION MANUAL 11 There are several different forms of communications networks. Maple Systems’ OITs utilize the multidrop format. The host controller, located at one of the network ends, is connected to the OITs via a continuous com-link. Each OIT is connected to the network by locally tapping into the com-link with short stub cables. The end of the com-link must be properly terminated to reduce noise pickup and interference. The total length of the com-link, from the host controller to the

12 MAP450D Network Termination The com-link cable must be properly terminated to reduce the amount of interference and noise pickup from the surrounding environment. This is accomplished by using a termination circuit at both ends of the network cable. The following figure shows a typical termination circuit. The host termination is only needed if the host controller’s RS-422/485 adapter does not contain any built-in terminator circuitry. The end termination must be done at the extreme end of th

INSTALLATION MANUAL 13 The cable shield must not be used as the signal ground. It is tempting to try and reduce the cost of 5-wire cabling by using a 4-wire cable with the shield used as the signal ground. DON’T DO IT. The initial cost savings are always exceeded by the maintenance costs once the system is operating under field conditions. It is often necessary to completely replace the network com-link with the proper cable (5-wire plus shield) to eliminate noise problems in the system. The sig

14 MAP450D 3. Mounting the MAP450D 3.1. Panel Mount The OIT is installed in a panel by separating the front and rear covers of the OIT, and then sandwiching the panel between the two. The gasketed surface of the OIT’s front cover provides the environmental seal to NEMA 4 and NEMA 12 standards. The rear cover helps shield the OIT from dust, dirt, induced electrical noise, and physical damage. The OIT is mounted using four #6-32UNC screws sandwiching the OIT halves to panel. Screw length is equal

INSTALLATION MANUAL 15 IMPORTANT: When panel mounting the MAP450D, do not catch the display connector on the panel cutout. The display is exposed while panel mounting and extra care should be taken. The display can be damaged if the display cable connector, which protrudes from the panel cutout, is touching the panel when tightened. To avoid damage, place the MAP450D gently onto the panel while monitoring for this condition. 3.2. Pedestal/Pendent Mount The OIT is installed onto a pedestal/penden

INSTALLATION MANUAL 17 4. Configuring the MAP450D The MAP450D has many operating parameters that control how it communicates to the host controller. These operating parameters can be changed in three ways: from the MAP450D’s keyboard when it is in Configuration mode, when the host controller sends a Configuration Control Command, or by downloading a STEPware-100 project. This chapter explains how to connect the MAP450D to a PC so you can download a project from the STEPware-100 configuration sof
