• 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 o ...

2.1. RS-232 (Interactive & Block modes) Interactive and Block modes support the 3-wire RS-232 configuration with TXD, RXD and signal common. The cable requires an overall shield to protect against electrical noise. Xon and Xoff can be used for communication handshaking. 3-Wire RS-232 Host Controller MAP450D Terminal Block TXD Pin 9 - RXD RXD Pi ...

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 ...

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 co ...

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 comp ...

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 ele ...

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 gen ...

The OIT is connected to the mounting plate with four #6-32UNC screws. The length of the mounting screws is equal to the plate thickness plus 1/4 inch. NOTE: The mounting screws must not be torqued to more than 18 pound-inches. Over-torquing can strip the threads in the enclosure. 3.3. Benchtop Mount The MAP450D’s rear cover has two legs set at a ...

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 projec ...
