Appendix E

E.1 Basic Network Layout

Multi-drop RS-485 implies that there are two main wires in an segment. The connected modules tap from these two lines with so called drop cables. Thus all connections are parallel and connecting or disconnecting of a node doesn’t affect the network as a whole. Since ADAM modules use the RS-485 standard, and use an ASCII-based commands set, they can connect and communicate with all ASCII- based computers and terminals. The basic layouts that can be used for an RS-485 network are:

Daisychain

The last module of a segment is a repeater. It is directly connected to the main-wires thereby ending the first segment and starting the next segment. Up to 32 addressable modules can be diasychained. This limitation is a physical one. When using more modules per segment the IC driver current rapidly decreases, causing communication errors. Totally the network can hold up to 256 addressable modules. The limitation for this number is the two number hexadecimal address codes that know 256 combinations. The ADAM converter, ADAM repeaters and the host computer are non addressable units and therefore are not included in these numbers.
