Tx Delay
Tx-delay is set in bits. It determines a delay to take place by the serial processor before
transmitting serial data to the port.
Depending on the baudrate chosen, and the number of bits, a time is calculated for Tx-delay.
»
Switch1 – as the serial processor only receives serial data, the tx-delay is of no affect.
»
Switch2- the Ethernet encapsulated data is received at router 2 and to its serial-processor. It is
then transmitted to CE2 via S1 following a time elapse of the tx-delay.
The serial-processor will delay transmitting the first serial byte to CE2. Following data bytes are
sent without delay.
Bus Idle Time
This parameter determines a silence on the serial line to identify frame end.
The configurable value for it is given in number of bits. Depending on the baudrate chosen, and
the number of bits, a time is calculated for bus-idle-time.
Byte mode
When using byte mode, end of byte is determined by stop bits. Bus-idle-time is not applicable at
this mode.
Frame mode
»
Switch1- the serial-processor will collect serial data transmitted from CE1 until a silence is
identified on the line for a time period equal or above the bus-idle-time.
»
Switch2- the serial-processor transmits the serial frames to CE2 while maintaining a gap
between frames. The gap is the bus-idle-time.
