    (AMC2-8IOE, AMC2-16IE, or AMC2-16IOE) can be connected. The extensions offer 8 or 16 additional inputs and outputs. The setup procedure for an AMC2-4R4 is made very simple and fast by the use of door templates. Once selected, all the inputs and outputs are predefined. These settings can be changed to choose every free contact of the controller or a connected extension.

  • Page 12: System Overview

    Using RS-485 reader interfaces, up to eight peripheral devices can be connected to each AMC2. The four reader interfaces are divided into two buses. Interface 1 and 2 are on one bus, and interfaces 3 and 4 are on the other bus. With this arrangement, you can connect all readers to one interface.
  • Page 13: Installing

    Installing Mounting The AMC2-4R4 can be attached on a standard 35 mm (1.377 in.) mounting rail using a snap-in mechanism. Attach the AMC2-4R4 into the upper edge of the mounting rail [1], then push down the device and snap it onto the rail by pushing it towards the back [2].
  • Page 14: Unmounting

    To remove the AMC2-4R4 from a mounting rail, first remove all pluggable connectors. Push down the AMC2-4R4 until the lower edge snaps out of the mounting rail [1]. Pull the lower end of the AMC2-4R4 from the mounting rail [2].
  • Page 15: Opening The Case

    To open the AMC2-4R4, first remove all pluggable connectors. The AMC2-4R4 case consists of a top cover mounted with a two-point snap-in closure on a chassis. To open the case, push down the two snap-ins with a screwdriver, then swing the cover down.
  • Page 16: Closing The Case

    [1]. Please ensure that the BOSCH logo is not upside-down. The upper edge of the front cover now aligns with the two-point snap-in closures on the upper edge of the back cover [2], and may thus be clicked gently into place.

  • Page 18: Grounding And Shielding

    AMC2 Modular Controller Grounding and Shielding The main grounding point at the AMC2-4R4 is connected to pin 2 of the power supply connector - see Connecting Diagrams, page 44. It is good practice to shield all wires carrying low level signals.
  • Page 19: Grounding For Extension Interface

    Jumper C (for the second bus) and jumper D (for the first bus) connects the internal ground of the AMC2 to the RS-485 ground of the bus. Only set jumper C and D (C2 or D2) if the AMC2 powers all other peripheral devices which are directly connected to the AMC2.

    Figure 4.9: Location of the Ethernet interface Notice! After connecting a new AMC2 device to a network using DHCP, it can take some time before the new AMC2 device is recognized by the remote server. You can accelerate this process by running the following command: ipconfig /flushdns This makes the AMC2 device immediately available by its name.

    Any bus line conductor connects up to eight AMC2. Do not exceed the maximum number of devices. To use RS-485 mode at the AMC2-4R4 , connect the data cables to the pluggable screw connector of the RS-485 host interface. The setting of the AMC2-4R4 must correspond with the settings of the RS-232 / RS-485 converter.
