Red Lion DLC - Manual (Page 2)

COMMUNICATIONS
The RS485 serial communications allows the DLC to be multi-dropped, with
Baud rates up to 38400. The CBPRO007 programming cable converts the
RS232 port of a PC to RS485 and is terminated with an RJ11 connector. The
bi-directional capability of the CBPRO007 allows it to be used as a permanent
interface cable as well as a programming cable.
SOFTWARE
The DLC is programmed with Windows ® based SFDLC software. The
software allows configuration and storage of DLC program files, as well as
calibration. Additionally, all setup and control parameters can be interrogated
and modified through MODBUS™ register and coil commands.
ANALOG OUTPUT OPTION
The optional dual DC Analog Output (10 V or 20 mA) can be independently
configured and scaled for control or re-transmission purposes. These outputs can
be assigned to separate channels, or both outputs can be assigned to the same
channel. Programmable output update time reduces valve or actuator activity.
