DPC-64-RS232
Transceiver Module
Introduction
The DPC-64-RS232 transceiver module provides a transparent serial link between two host
devices, where packets of up to 64 bytes of data may be transceived. All data encoding, decoding
and error checking is performed by the DPC-64-RS232 leaving nothing more for the host to do,
other than sending data in x.8.N.1 serial format to the DPC. The serial data sent by the host to
the DPC is automatically encoded and packetized and then transmitted over the air to the
receiving DPC.
Upon receipt of the radio data transmission, the DPC will decode the data, perform an error check
and output the original data to the receiving host.
Power Supply
Although the operating supply range is from 7.5Vdc to 15Vdc, 20mA, the DPC is supplied
standard with a 9V battery connector – alternative power sources within range may of course be
used. Polarity should be observed. As a protective measure for the host equipment, we
recommend applying power to the DPC only after it has been connected to the host.
Serial interface
The DPC-64-RS232 transceiver implements a standard serial interface and is configured as a
DTE.Connection to, for example, a personal computer COM port can be made using a standard
DB9 connector serial extension cable having a one male and one female connector.

... DPC has received 64 bytes, the DPC will signal the host to pause sending data allowing it to transmit the 64 bytes of data to the receiving DPC. Once the DPC has transmitted the data, the CTS flow control line will toggle, allowing the DPC to receive the next 64 bytes of data from the host. ...
