Appendix B: Remote Control

DS1000 Series User Manual

B–3

Programming Model

The television demodulator uses the BCP Simplified Communication
Link protocol (SCL). With the SCL Protocol, you program a PC to
send and receive data using standard I/O functions found in most
programming languages, such as C, PASCAL, and BASIC.

The SCL protocol supports asynchronous binary communication, not
text or ASCII based. Communication is based on 8-bit bytes ranging
from 0 to 255. Table B–2 lists special byte codes used to coordinate
data transfers between the PC and the television demodulator. For
information on how to use these special byte codes, refer to Sending
and Receiving Data on page B–5.
