RS-232 or 10/100 Mbit/s Ethernet. It has eight analog input devices and eight relay outputs. With its analog input devices, the AMC2-4R4 verifies, for example, if a lock is closed or open. The relay outputs can be used to activate lock mechanisms if access is granted, or activate the...
(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.

Connectors for eight analog inputs Connectors for eight relay outputs Notice! All connectors, with the exception of the RS-232 and Ethernet host interface, are pluggable screw clamp terminals.

Figure 3.6: Jumper at the bottom side Jumper for setting either voltage free relay output (“dry” mode) or looped-in voltage from the AMC2 internal power supply (“wet” mode). Jumper: Potential equalization between different systems and earth ground (shield) for the bus systems.
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.
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].
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].
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.
[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.

These specifications apply to power supply, readers, relay outputs, and extension interface. Regarding inputs, specific voltage-drop values need to be taken into account. Refer to Connecting Analog Input Devices, page 33. Bosch Access Systems GmbH Installation Manual 2018-02 | AMC2-4R4 |...
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.
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.
Connecting Diagrams, page 44 for a complete diagram of the power supply connector. Figure 4.8: Location of the power supply connector Connect an external power supply (10 - 14 Vdc) for the AMC2 device at pin 1 (positive) and pin 3 (0 V) of the pluggable screw connector.
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.
| Installing AMC2 Modular Controller RS-485 Host Interface An RS-485 host system can consist of up to eight AMC2 controllers connected using 2- or 4- wire connection. Figure 4.10: Configuration of a RS-485 host system Host RS-232 connection RS-232 / RS-485 converter...
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.
Figure 4.13: Settings for RS-485 four wire connection Notice! See the notices for setting the RS-232 / RS-485 converter. Notice! If a four-wire connection is used the interface must be set up as a crosslink. 2018-02 | AMC2-4R4 | Installation Manual Bosch Access Systems GmbH...
Cable length between two RS-232 COM serial interfaces must not exceed 15 meters (45 ft). Figure 4.14: Location of the RS-232 serial interface As the AMC2 controller is conceptionally a PC, it is not possible to connect them directly using normal cables. Use instead a null modem or “crossover” cable. A complete connection...
DIL switches are used to configure the host settings. The first four DIL switches for address selection define the RS-485 address of the AMC2 in a RS-485 bus system. Switch 5 selects one of the two different protocols, SDEB and BPA (according to DIN6619).

All eight possible readers can connect to each of the busses in any combination. However, the addresses of the readers must be unique on an AMC2. The voltage on the interface is equal to the input voltage of the AMC2-4R4 A complete connection diagram of the RS-485 interface is shown in chapter Connecting Diagrams, page 44.
4.14 Connecting Relay Outputs To operate locks or alarm systems, the AMC2-4R4 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 44.
