RabbitCore RCM3305/RCM3315

B.4.6.2 RS-485

The Prototyping Board has one RS-485 serial channel, which is connected to the Rabbit
3000 Serial Port C through an RS-485 transceiver. The half-duplex communication uses
an output from PD7 on the Rabbit 3000 to control the transmit enable on the communica-
tion line. Using this scheme a strict master/slave relationship must exist between devices
to insure that no two devices attempt to drive the bus simultaneously.

Serial Port C is configured in software for RS-485 as follows.

#define ser485open serCopen

#define ser485close serCclose

#define ser485wrFlush serCwrFlush

#define ser485rdFlush serCrdFlush

#define ser485putc serCputc

#define ser485getc serCgetc

#define CINBUFSIZE 15

#define COUTBUFSIZE 15

#ifndef _485BAUD

#define _485BAUD 115200

#endif

The configuration shown above is based on circular buffers. RS-485 configuration may
also be done using functions from the

PACKET.LIB

library.

The Prototyping Boards with RCM3305/RCM3315 modules installed can be used in an
RS-485 multidrop network spanning up to 1200 m (4000 ft), and there can be as many as
32 attached devices. Connect the 485+ to 485+ and 485– to 485– using single twisted-pair
wires as shown in Figure B-8. Note that a common ground is recommended.
