HMP260 SERIES

Appendix 1: Serial commands HMP260-U017en-1.5

The settings can be changed one parameter at a time or all parameters at once:

SERI O H <cr> changing parity and duplex

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 HMP260

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.

UNIT Selecting the output units

UNIT x <cr>

x = m(etric units)

n(on-metric units)

metric units non-metric units

RH %RH %RH

T °C °F

Td °C °F

a g/m

gr/ft

x g/kg gr/lb

Tw °C °F

For example, the command for setting the non-metric units is:

UNIT N <cr>

Output units : non metric

When the command is given with no parameters, the transmitter outputs the currently

valid setting.

1 2 ... 76 77 78 79 80 81 82 83 84 85 86 ... 117 118
