Networking Commands
Set the RS-422/485 interface by using the following commands. The
other serial line commands are presented in section List of Serial
Commands on page 87.
RS-485 configuration commands SERI, ECHO, SMODE, INTV, and
ADDR may be entered by using either the service port or RS-422/485
port. Also the optional display/keypad can be used, see section User Port
Serial Settings on page 102.
SDELAY

delay). The value can be set between 0 ... 254.
