dpc-9600

Manufacturer Part Number
dpc-9600
Description
9600bps Serial Data Encoder/decoder Chip
Manufacturer
ABACOM Technologies, Inc
Datasheet
DPC-9600
Interfacing the DPC-9600 data packet controller between any serial data host such as a PC or microprocessor
and any of ABACOM’s transmitter and receiver modules provides a quick and easy, single chip solution to
data formating and data packetizing requirements necessary for successful wireless serial data
communications. The DPC-9600 saves the designer the burden and time of having to write their own code to
packetize and encode/decode their data.
The DPC-9600 is ideal for (but not limited to) applications that require the sending of short ‘control and sense’
type commands as typically used in:
By implementing the BUSY control line, data consisting of more than eight bytes can be automatically trans-
mitted.
