0x80 3 ZNA (HIGH byte) Time after request (ZNA)
Waiting time to be complied with until the next transmit
request is executed.

4 ZNA (LOW byte) 0x00
Option 4 / 5, character delay time
0x80 5 Character delay time
(HIGH byte)
Character delay time; the character delay time defines the
max. permissible interval between two received characters
within a frame.
If the character delay time is 0, the module independently
calculates the character delay time on the basis of the baud
rate (approx. the double character time).

Option 6, number of receive buffers
0x80 7 Number of receive
buffers
Defines the number of receive buffers. As long as only one
receive buffer is used and is assigned, no more data can be
received. If up to 250 receive buffers are connected, the
received data can be redirected to a still free receive buffer.

Option 13, operating mode
0x80 14 Operating mode The operating mode determines if the interface is to be
operated half duplex (RS485) or full duplex (RS422).
• 0x00: Half duplex - two-wire operation (RS485)
Half duplex operation means that either transmission or
reception can take place at a time. The data are
transmitted between the communication partners
alternately in both directions.
In case of the half duplex parametersetting under RS485,
no software data flow control is possible.
• 0x01: Full duplex - four-wire operation (RS422)
The data are exchanged simultaneously between the
communication partners; transmission and reception can
take place at the same time. Each communication partner
must simultaneously actuate a receive path.
