The transmission format may be summarized as follows:

start bit

data bit 0

data bit 1

data bit 2

data bit 3

data bit 4

data bit 5

data bit 6

data bit 7

even parity bit (optional)

one stop bit

The 1775–KA module selects baud and parity through the LIST function

(section titled Programmable Configuration Parameters).

A number of installation parameters for the 1775–KA module can be

programmed through the PLC–3 LIST function.

The LIST function words by presenting you with a series of lists, or

menus, that allows you to select and establish the module’s operating

parameters. Each option in an upper–level menu represents a submenu of

more detailed options. This process continues until you have selected

enough options to define a single parameter in full detail. Figure 2.11

illustrates the menu structure of LIST. To return to the preceding (next

highest) level of LIST, press the ENTER key without making a new entry.
