8 Character delay time 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).

13 Priority A communication partner has high priority if the
transmission attempt has priority over the partner’s
request to transmit. With a low priority, the partner’s
request to transmit comes first. In case of the protocols
3964(R), both partners must have different priorities.
