dl2000-kfx

df1 to dh+
Dual Port - DF1 to DH+ Controller



The DataLink DL2000-K2F connects two serial devices using A-B serial DF1 Protocol to a single Allen-Bradley Data Highway Plus. This unit is similar to having two A-B 1770-KF2s or two DL2000-KFXs in a single enclosure and each serial port has its own DH+ station address. The primary serial port is configured for any DH+ station number (base address) is capable of serial communications of up to 115.2 Kbaud (RS232 or RS422 / RS485), Point-to-Point (full-duplex) or Multi-drop (half-duplex), and can be set to use Handshaking. The second serial channel is automatically configured to the next higher DH+ station address and is capable of serial communications of up to 38.4 Kbaud (RS232 or RS422) and Point-to-Point, no Handshaking. Both serial ports must use the same message check method (either BCC or CRC) and share common DF1 protocol parameters such as Execute or Pass Diagnostic command.

Two Serial Ports in One Unit:
Second interface increases DH+ accessibility

Compact and Lightweight:
Small size for installation convenience and portability

Flexible Serial Interfacing:
RS232C and RS422/RS485

Easy Configuration:
All parameters are menu-driven

Increased Throughput:
Serial and DH+ communications at speeds up to 115.2 Kbaud
