| Introduction Access Modular Controller 2 System overview The controller is connected to the host system via RS485 or Ethernet, depending on the type of installation. The host interface is selected during installation. The four interfaces are available on the device by default. With RS485 operation, a maximum of eight access controllers can be connected to one party line.
Access Modular Controller 2 Installing | en Installing Mounting the device on a mounting rail The controller can be attached on a standard 35 mm (1.377 in.) mounting rail using a snap-in mechanism. Attach the controller 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].
| Installing Access Modular Controller 2 Opening the case Notice! To open the controller, first remove all pluggable connectors. The controller’s 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.
[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.
| Installing Access Modular Controller 2 Cabling Notice! Risk of malfunction The cables used in the controller are not prone to electrical interference. However, you should avoid routing cables close to heavy load switching cables and equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft) to reduce interference.
Access Modular Controller 2 Installing | en Grounding and shielding The main grounding point at the controller is connected to pin 2 of the power supply connector - see Connecting diagrams. It is good practice to shield all wires carrying low level signals.
| Installing Access Modular Controller 2 4.6.2 Gounding for Extension Interface B 1: Delivery status B 2: Figure 4.6: Location of ground jumper bottom side Jumper B connects the internal ground of the controller to the RS-485 ground of the slave interface.
Connect an external power supply (10 VDC - 30 VDC) to the controller at pin 1 (positive) and pin 3 (0 V) of the pluggable screw connector. Bosch recommends using the Bosch APS-PSU-60 power supply unit. This power supply can also be used as an uninterpretable power supply (UPS) when using the appropriate batteries.
When using an Ethernet connection, switches 1 and 5 of the DIP switch must be set to the ON position (= factory setting) (see Figure 3.3, item 1 , page 10 ). This also ensures correct communication with the Bosch Building Integration System (BIS) and the Bosch Access Management System (AMS).
Access Modular Controller 2 Installing | en RS-485 host interface The RS-485 host interface of the controller can be set for using a 2- or 4-wire connection. Up to eight controllers can be used on one host bus. RS 232 RS 485 Figure 4.9: Configuration of a RS-485 host system...

Figure 4.14: Location of the RS-485 extension module bus Up to three expansion modules can be connected to provide additional in- and outputs, for example, for elevator control.
Access Modular Controller 2 Installing | en 4.11 Wiegand interface for card readers The AMC2 provides four ports for connecting a maximum of 4 readers with Wiegand interfaces. Each interface is connected using a 10-pin pluggable screw - refer to Connecting diagrams, page 46 .
| Installing Access Modular Controller 2 4.12 Connecting relay outputs To operate locks or alarm systems, the AMC2 has eight relay outputs. The outputs will be connected to the 3-pin pluggable screw connectors S5, S6, S10, S11, S17, S18, S22 and S23 - refer to chapter Connecting diagrams, page 46 .

Access Modular Controller 2 Installing | en To detect the four states, the voltage drop in the connecting cable may not exceed special values. The following table shows the maximum values of permissible cable resistance depending on the used resistor combination.
| Installing Access Modular Controller 2 4.14 Tamper protection To protect the AMC2 against unauthorized access and so prevent tampering with sensitive data, the AMC2 provides an additional interface to connect external tamper contacts. This interface is a potential-free 2-pin pluggable screw connector marked with T. When not in use this tamper contact should be shorted.
Access Modular Controller 2 Operating | en Operating Configuring Ethernet interface To configure the controller in a TCP/IP network environment, use the AccessIPConfig tool. The tool is delivered with the access host system software. Consult the online help of the AccessIpConfig for details on configuring the controller.
The enclosures AMC2-UL01 (for one device) or AMC2-UL02 (for two devices). – For every enclosure, a power supply Bosch APS-PSU-60 is necessary, and must be located in the same room as the connected AMC2 device. Recommended maximum distance between power supply unit and AMC2 is 3 m (9.84 ft).
It may not be used for connection to readers or other accessories. – All units are to be powered by the Bosch APS-PSU-60 power supply for UL installations. The power supply must be located in the same room as the connected AMC2 device.
