DL2000-ASM
ASCII Serial Interface

The DataLink DL2000-ASM is a compact freestanding ASCII serial interface that enables scanning devices to write to PLC integer files via Data Highway Plus. This facilitates ASCII data transfer to any PLC including models without an ASCII port, such as A-B’s ControlLogix. A block of data is temporarily stored in the ASM’s 240-byte buffer until the buffer is filled or an ASCII carriage return is detected in the data. Once the data is terminated, the bytes are transmitted to the PLC in DH+ protocol format.  All bytes are retransmitted in the order they were received minus the carriage return.

Features:

Flexible System Layout: scanners located anywhere on a DH+ network can send ASCII messages to PLCs in other locations
Compact and Lightweight: Small footprint for installation convenience
Easy Configuration: All parameters are menu-driven
High Speed: Serial speeds from 300 baud to 19.2 Kbaud and also 57.6 Kbaud
