SERIAL INTERFACE

AMS offers two adapters to facilitate party line connect; models SIN-8 and SIN-10. The SIN-10 costs slightly more but is so powerful that the software programming is simplified. Some operating systems (Windows 2000) are close to impossible to program properly.

SIN-8 Serial Adapter

The SIN-8, RS-232 to RS-422 serial data converter, is used with party line network designs. Any number between one and thirty-two axes can be connected in a mini-drop network system.

RS-422/485 BUS-drop

The bi-directional adapter is powered from the AMS controller. A switch is provided to select the single-axis mode in order to assign the required axis "name" character. The serial communication requires a "character by character" handshake protocol that may not be practical with all computer operating systems.
