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. 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 2-30
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 unit. The KB0 port end of the serial
programming cable requires a male DA-9P style connector, wired as shown in
Figure 2-30 .
4. If the PI device is a personal computer equipped with a DA-9P connector, wire
the connectors according to
Figure 2-30 .
5. For installations with a permanent PI device, route the serial data cable from
the PI device to the front panel of the unit and connect it to the KB0
connector.
