2.5.5 Testing all outputs
It is possible to request the status of all slot outputs using the following
command:
LO<CR>
The terminal responds with the following string:
n1n2n3<CR><LF>
where:
n1 is 1 character which is the logical combination of the status (0
or 1) of the outputs (max. 2) on board the terminal. It can have
values between 0 (30H) and 3 (33H).
n2 is 1 character which is the logical combination of the status (0
or 1) of the outputs (max.4) on slot 1. It can have values from 0
(30H) to F (46H). If there is no slot 1, n2 will have a value of " - " (2DH).
n3 is a character which is the logical combination of the status (0
or 1) of the outputs (max. 4) on slot 2. It can have values from 0
(30H) to F (46H). If there is no slot 1, n2 will have a value of " - " (2DH).
the lines are set up as follows:
bit3 bit2 bit1 bit0
line 4 line 3 line 2 line 1
where the lines have values of 0 or 1.
For example, if the following command is received:
184<CR><LF>
1 8 4
01 1000 0100
where:
01 lines on slot 1: line 1 active (bit 0 = 1), line 2 (bit 1 = 0) not
active;
1000 lines on board: line 1 (bit 0 = 0), 2 (bit 1 = 0), 3 (bit 2 = 0)
not active, line 4 (bit = 1) active;
0100 lines on slot 2: line 1 (bit 0 = 0), 2 (bit 1 = 0), 4 (bit 3 = 0)
not active, line 3 (bit 2 = 1) active;
2.5.6 Change the status of all outputs
It is possible to change the status of all slot outputs using the following
command:
n1n2n3WO<CR>
where:
n1 is 1 character which is the logical combination of the status (0
or 1) of the outputs (max. 2) on board the terminal. It can have
values between 0 (30H) and 3 (33H).
n2 is 1 character which is the logical combination of the status (0
or 1) of the outputs (max.4) on slot 1. It can have values from 0
(30H) to F (46H).
n3 is a character which is the logical combination of the status (0
or 1) of the outputs (max. 4) on slot 2. It can have values from 0
(30H) to F (46H).
