Telegram structure :
In case of cyclic transmission SIMO the blocking time determinated LIAN is followed between two telegrams ( independently of the command "fe" ).
During receipt a break of at least the blocking time parameterized in LIAN is expected between two telegrams. If the blocking time is parameterized too short receipt failures may occur.
If you choose "Telegram with pre-pulse" a so-called start pulse ( pre-pulse and a call sign of length 20 ms is transmitted ahead of the actual telegram. The length of the start pulse is parameterized in LIAN in milliseconds ( 0 - 999 ). It is independent of the set baud rate.
In SIMO you can activate a bit shifter via the command 'bs'.It enables you to set a bit conveniently into the information block of the relevant telegram. When exceeding the information area the message address is automatically increased or reduced.
|In the window "bit shifter" you can use the following commands :|
|[ 1-9 ]||define interval "n"|
|[ arrow-right ]||n bit to the right|
|[ arrow-left ]||n bit to the left|
|[ arrow-up ]||increase message address by 1|
|[ arrow-down ]||reduce message address by 1|
|[ S ]||send message|
|[ ESC ]||quit entry mask|
It should be taken into the account that the bit shifter doesn't change the message address and the information block ; previous settings are not lost.
|*F:Block length :||The telegram is too short or too long.|
|*F:Timetolerance :||The received sign cannot be identified clearly ( => parameter "tolerance limit" in LIAN ).|
|*F:Spike :||The received sign is < 20% of a short pulse.|
|*F:2 out of 5-Code :||The address is faulty.|
|*F:Parity :||One of the check signs is wrong.|
|*F:SYNC :||The start sign is incorrect.|
