Setting Commands

SERI Setting the Serial Communication

Parameters

Syntax: SERI [baud] [parity] [bits] [stops]

[duplex]<cr>

where

[baud] = 300/600/1200/2400/4800/9600/19200/38400/57600/1

15200

[parity] = N (none)/E (even)/O (odd)

[bits] = 7 (7 bits)/ 8 (8 bits)

[stops] = 1 (1 stop bit)/2 (2 stop bits)

[duplex] = H(half-duplex)/F (full-duplex)

The current settings are output if you give the command without the

parameter fields. Factory default: 9600/8/none/1.

The fields can be given in any order. The new settings are valid

immediately after the change. If you choose a half-duplex mode, the

echo turns automatically into OFF-position.

19200 N 8 1 FDX

UNIT Setting the Units

Syntax: UNIT [x]<cr>

where

x = unit C or F (dewpoint, temperature, wet-bulb temperature),

g/m3 or gr/ft3 (absolute humidity), g/kg or gr/lb (mixing

ratio), kJ/kg or btu/lb (enthalpy), hPa or torr or psi or bar

(pressure), slpm or scfh (sample flow).

x=m (metric)or n (non-metric)

The unit is set by typing the desired unit(s) after the command UNIT.

All the units change form metric to non-metric (or other way round)

by typing UNIT m or UNIT n. The display units change

simultaneously.
