Chapter 7. TERMINAL MODE
This chapter defines the protocol and command structure for remote control and status
monitoring of the KST-2000L in the terminal mode of the Windows™ based M&C
remote control software and on the KP-10 keypad.
7.1
General
Remote control and status information are transferred via a EIA-485, EIA-422 or
EIA-232C serial communications link. Commands and data are transferred on the remote
control communications link as ASCII encoded character strings. The remote
communications link is operated in a half duplex mode. Communications on the remote
link are initiated by a remote controller or terminal. The KST-2000L never transmits
data on the link unless it is commanded to do so.
7.2
Message Structure
The ASCII character format used requires 11 bits/character: 1 start bit and 7 information
bits plus 1 parity bit (odd/even), or 8 information bits with no parity bit (none) and 2 stop
bits. Messages on the remote link fall into the categories of commands and responses.
Commands are messages which are transmitted to the KST-2000L, while responses are
messages returned by the KST-2000L in response to a command.
