3.9 REMOTE OPERATION
The programmer can be operated externally using three
different remote control modes. Two of the modes are
standard to the programmer and are described in this
section. They are the Computer Remote Control (CRC) and
System Remote Control (SRC). The third mode is the
optional Terminal Remote Control (TRC) mode which is
covered in Appendix B of this manual.
CRC is the preferred mode of operation and should be
used for all new driver designs. Both SRC and TRC are
included mainly to accomodate user's whose existing
operations have software and/ or hardware requiring either
of those modes of operation.
3.9.1 COMPUTER REMOTE CONTROL
CRC is designed to enable control of the 298 Programmer
by a computer. Linked directly to the programmer, the
computer generates and sends commands to the
programmer, determines variables for setting programming
parameters (where needed), and reacts to information
returned to it from the programmer.
While these commands may be sent by an operator at a
terminal, the commands and syntax described in this
manual were designed to be easily incorporated into a
computer program.
Installation
The 298 with CRC must be connected to the computer
according to RS232C specifications. The function of each
serial port pin connection is described in subsection 2.5 of
this manual. Refer to table 2-2 to determine the necessary
connector pins for serial data transfers. The programmer's
baud rate, parity, and stop bit settings are described in
subsection 2.5.2.
Overview
Figure 3-4 illustrates the basic components of the 298
under computer remote control. 298 CRC remote control
operation is controlled by the user's computer. The user
must provide application software which will allow his
computer to issue CRC commands and to interpret CRC
responses.
Data transferred between the computer and the 298 is
generally in ASCII notation, encoded in the selected data
translation format (see Appendix A), although straight
binary transfer is also possible.
Commands are generated by the computer according to
the computer's software or in response to keyboard
entries. The computer sends commands to the 298 which
executes the command (or tries to) and then sends back a
response character.
