Program Interface Device Connection
The data terminal or personal computer that will be used as the Program
Interface (PI) device must be equipped with an RS-232E asynchronous
serial data interface that can be configured for a data rate of 19200, 9600,
4800, 1200, or 300 bps, 8 data bits, 1stop bit, and no parity bit or EVEN,
ODD, mark, space, and parity. A data rate of 38,400 is also recommended.
Data rates of 57600 and 115200 are optional. The PI device must use the
ASCII character set. The ground connection to the PI device must be the
same ground connection supplied to the Coral system.
1. Unpack the PI device and prepare it for operation. Set the interface for a data rate
of 9600 bps, 8 data bits, 1 stop bit, and no parity bit. These are the default settings
for all serial programming ports of the Coral system.
2. Determine the connector type and pin assignments for the data interface of the PI
device.
Figure 2-45
shows the connections for using data terminals with a 25 pin
DB-25P (male) or DB-25S (female) connector.
Figure 2-46
shows the connections for
using personal computers with a DA-9P connector for the serial interface.
3. Obtain or prepare a serial data cable to connect the PI device to the KB0 serial
programming port on the front side of the MCP-IPx card. The KB0 port end of the
serial programming cable requires a male DA-9P style connector, wired as shown
in either
Figure 2-45
or
Figure 2-46
.
4. If the PI device uses a DB-25P or DB-25S connector, wire the connectors according
to
Figure 2-45
. If the PI device is a personal computer equipped with a DA-9P
connector, wire the connectors according to
Figure 2-46
.
5. For installations with a permanent PI device, route the serial data cable from the
PI device to the front cover of the cage and connect it to the KB0 connector.
