DL3500-DH+/ASCII
ASCII Serial Interface
The newest DataLink DL3500-DH+/ASCII (ASCII DH+) is an amalgamation of two existing products: the DL3000-ASM and the DL3000-ASC. The improved compact freestanding ASCII serial interface gives customers the ability to send as well as receive ASCII messages via A-B Data Highway Plus (DH+).
 ASCII DH+ dl3500 The DL3000-ASM 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's integer files in DH+ protocol format. All bytes are retransmitted in the order they were received minus the carriage return.
 The DL3000-ASM now has the added functionality of the DL3000-ASC, enabling ASCII messages stored in PLC-5 data tables to be transferred over DH+ (Data Highway Plus) to a serial printer or message display.
The -ASM is specifically designed to buffer DH+ (Data Highway Plus) message commands sent to its station address from any PLC-5. The transmitted ASCII bytes are then flipped to produce messages on the printer in the same order as the ASCII data is entered and displayed in the PLC.
Features:
Flexible System Layout: scanners, printers, and message displays located anywhere on a DH+ network can send and receive ASCII messages to and from PLCs in other locations
