Serial bus settings
SERI b p d s x <cr>
b = bauds (300, 600, 1200, 2400, 4800, 9600)
p = parity (n = none, e = even, o = odd)
d = data bits (7 or 8)
s = stop bits (1 or 2)
x = duplex (H = half, F = full)
The settings can be changed one parameter at a time or all parameters
at once:
>SERI O <cr> changing parity only
4800 O 7 1 HDX
>SERI 600 N 8 1 F <cr> changing all parameters
600 N 8 1 FDX
The processor does not allow the following combinations:
• no parity, 7 data bits, 1 stop bit: if this combination is given the
DMP248 programme will change the number of stop bits to 2
• even or odd parity, 8 data bits, 2 stop bits: if this combination is
given the programme changes the number of stop bits to 1
NOTE
The serial bus settings become effective only after reset.
When the half-duplex mode is set, it will automatically turn the echo
off. Even then, the ECHO command can indicate that echo is on.
Selecting the output units
UNIT x <cr>
x = m / n
m= metric units (°C)
n= non-metric units) (°F)
Setting the transmitter address
ADDR aa <cr>
aa = address (0...99)
Example: transmitter is given address 99
>ADDR <cr>
Address : 2 ? 99 <cr>
