Answer delay
delay for answers,
from 0 to 1000 mSec.
At menu ‘Conguraon ASCII’ (‘AScI’), congure the instrument at
parameter ‘Mode’ (‘ModE’) to work as ‘slave’ or ‘master’, at param-
eter ‘Address’ (‘Addr’) set the address value from ‘1’ to ‘31’, set the
bus speed in kbps at parameter ‘Speed’ (‘bAud’) and set the data
format at parameter ‘Format’ (‘bItS’).
When working as ‘master’, the instrument connuously transmits
the display value data frame. The local module address is ‘0’. Con-
gure at menu ‘Conguraon Master’ (‘cnF.M’) the ‘Desnaon ad-
dress’ (‘d.Add’) parameter from ‘1’ to ‘31’ or use value ‘128’ for a
broadcast message. At parameter ‘Frequency’ (‘FrEq’) select the how
oen the frame with the reading value will be transmied.
Special tools are grouped inside the ‘Tools’ (‘TooL’) menu.
• the ‘Decimal point’ (‘dP’) menu is provided for compability with
ancient hardware that does not support decimal point retransmis-
sion. By default, select ‘Automac’ (‘Auto’). If your instrument
does nos transmit the decimal point posion, select ‘Manual’
(‘MAnL’) and x the posion of the decimal point manually.
•the ‘Legacy mode’ (‘LEG’) parameter is provided to maintain
compability with instruments with older communicaon proto-
cols. Select ‘on’ to acvate this mode.
• the ‘Answer delay’ (‘AnS.d’) parameter applies only to ‘Slave’
mode. The local module delays the answer frame. Congure for
applicaons where the ‘Master’ needs addional me to switch
between ‘transmit’ and ‘receive’ modes. Enter a numeric value be-
tween ‘0’ and ‘1000’ mSeconds.
• at the ‘Factory reset’ (‘FAct’) menu, select ‘yes’ to load the de-
fault factory conguraon for the instrument.
the ‘Version’ (‘VEr’) menu informs of the current rmware version
installed in the module.
