2.5.3 Testing a single output
It is possible to request the status of every output using the command:
TO n1 n2 <CR>
where:
n1 is 1 hexadecimal character that defines the position of the output
slot;
n2 is 1 hexadecimal character that defines the output number on
slot n1.
n1 = 0 (30H) output on the terminal
n1 = 1 (31H) output on slot 1
n1 = 2 (32H) output on slot 2
n2 = 1 (31H) output number 1
n2 = 2 (32H) output number 2
n2 = 3 (33H) output number 3
n2 = 4 (34H) output number 4
The terminal responds with one of the following messages:
1<CR><LF>
if the output is active;
0<CR><LF>
if the output is not active;
-<CR><LF>
if there is no slot.
2.5.4 Testing a single input
It is possible to request the status of every input using the command:
TI n1 n2 <CR>
where:
n1 is 1 hexadecimal character that defines the slot position of the input;
n2 is 1 hexadecimal character that defines the input number on slot
n1.
n1 = 0 (30H) input on the terminal
n1 = 1 (31H) input on slot 1
n1 = 2 (32H) input on slot 2
n2 = 1 (31H) input number 1
n2 = 2 (32H) input number 2
n2 = 3 (33H) input number 3
n2 = 4 (34H) input number 4
The terminal responds with one of the following messages:
1<CR><LF>
if the input is active;
0<CR><LF>
if the input is not active;
-<CR><LF>
if there is no slot.
