5.4.2.3 Outputting the reading once

SEND <cr> in STOP mode

SEND aa <cr> in POLL mode

aa = address of the transmitter when more than one transmitter

is connected to a serial bus (0...99)

The output format depends on which parameters the transmitter can output.

Output types:

"Td=999.9 'C", <cr><lf>

"RH=999.9 %RH T=999.9 'C Td=9999.9 'C",<cr><lf>

"Td=999.9 x=999.9 g/kg",<cr><lf>

"RH=999.9 %RH T=999.9 'C Td=9999.9 'C a=9999.9 g/m3

x=9999.9 g/kg Tw=999.9 'C",<cr><lf>

The output mode can be changed with command FORM (see Appendix 1).

5.4.2.4 Setting the output interval for the RUN mode

INTV xxx yyy <cr>

xxx = output interval (0...255)

(0 = no pause between outputs)

yyy = unit (s, min or h)

Example: output interval is changed into 10 minutes

>INTV 10 min <cr>

Output intrv. : 10 min

5.4.2.5 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:

1 2 ... 34 35 36 37 38 39 40 41 42 43 44 ... 129 130
