DL2000-K2F:
Dual Port - DF1 to DH+ Controller

The 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.
