Output the Measurement Message Once

Use the SEND command to output the measurement values once. If the

probe is in POLL mode and line is not open for commands, specify the

address of the probe to receive the measurement message.

SEND [aaa]<cr>

where

aaa = Address of the probe, range 0 ... 254. Set with the ADDR

command.

Example (probe in STOP mode, no address needed):

send

T= 22.7 'C RH= 20.0 %RH Td= -1.5 'C

Example (probe in POLL mode, with address 10):

send 10

T= 22.8 'C RH= 20.1 %RH Td= -1.3 'C

Configuring Serial Line Operation

Set Serial Line Settings

Use the SERI command to show or set the serial line settings. The new

settings will be taken into use when the probe is reset or powered up.

SERI [b p d s]<cr>

where

b = baud rate

(300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600)

p = parity (n = none, e = even, o = odd)

d = data bits (7 or 8)

s = stop bits (1 or 2)

1 2 ... 32 33 34 35 36 37 38 39 40 41 42 ... 63 64
