Internet Control System Protocol (ICSP)

AMX devices communicate with each other using a proprietary low level protocol called Internet Control

System Protocol (ICSP). This protocol can be carried over the Ethernet TCP/IP connection, RS232 PPP

connection, and ICSNet connection to devices. ICSP is routable within AMX devices independent of

transport medium. Each ICSP client device is logically bound to a single Central Controller. If a second

Central Controller need to communicate with a client device the ICSP communication is sent to the

Central Controller the device is bound to and it is relayed to the client device through a Central

Controller to Central Controller (M2M) connection.

ICSP may also be encrypted where required by the environment. Encrypted ICSP uses a Challenge-

Handshake Authentication Protocol (CHAP) with a three way handshake using the MD5 hash algorithm.

The encryption is ARC4 with a commonly derived key, with no key information is passed between the

hosts. The entire ICSP packet, including headers, is encrypted and the resulting data encapsulated in a

new eICSP packet.

Device Addressing

Each ICSP Device, regardless of transport type is addressed with a unique combination of System and

Device with sub-addresses within Devices termed Ports. Addressing is specified as Device:Port:System

(D:P:S)

System ID is associated with a logical Central Controller (1 Central Controller per System ID). Valid

System numbers are 1 to 65535 and are unique within the network. System 0 is a wildcard referring to

the local system

Device Number is bound to a single Central Controller (multiple Devices per Central Controller). Device

numbers are unique within the System they are bound to. There is a limit of 200 devices bound to a

single controller. Many devices have range limitations on the device number that may be used. If an

incorrect device number outside of that range is assigned to a particular device, the module may not

function properly.
