Chapter 5: Operation

Table 5-1. RS-232 Controller Card response to “help” command (1200, N, 8, 1).

Rack 1 switch Rev A Commands: get system

get rack n (n = rack addr, 1 to 255) get port y (y = port addr, 1 to 4080) get version n (n = rack addr, 1 to 255) set system X (X = A or B)

set rack n X (n = rack addr, 1 to 255, X = A or B) set port y X (y = port addr, 1 to 4080, X = A or B) help (displays current commands)

SPACE (space character starts terminal mode) exit (exit terminal mode)

>

NOTE: For commands that use a rack address “n,” refer to Section 3 for information on how to set the rack address DIP switch SW2. Each rack can contain up to 16 ports. Rack 1 is assigned port numbers 1 through 16, rack 2 is assigned port numbers 17 through 32, and so on. For commands that use a port address “y”, use the following formula to determine the port address of any port in any rack: y = 16*(rack address – 1) + port#

Example: Port 12 in rack 3 has port address 44.

Commands are not case sensitive and can be entered as either upper or lower case. The terminal interface echoes each character it receives back to your terminal, allowing the user to backspace to correct typing errors. Each word on a command line must be separated by a single SPACE character. The command is processed when you press the ENTER KEY. All of the above commands except “help” and “exit” may be abbreviated by using only the first character of each word on the command line. For example:

“g s<CR>” is the same as “get system<CR>”.

“s r 2 A<CR>” is the same as “set rack 2 A<CR>”.

Table 5-2 shows an example of each command along with the expected Response and Action.

NOTE: Each command must be followed by a carriage return (ASCII HEX 0x0D).
