When selecting an RS-232-RS-485 converter for the network, avoid
self powered converters as they don't necessarily support the needed
power consumption.
Echo function shall be always disabled (OFF) when using the 2-wire
connection. When using the 4-wire connection you can disable/enable
the echo setting.
NOTE
User port on transmitter main board cannot be used and connected
when RS-485 module is connected. Service port is operating
normally.
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 85.

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 96.
SDELAY
With the
SDELAY
command you can set delay (response time) for
user port (RS232 or RS485), or view currently set delay value. Value
corresponds to tens of milliseconds (eg. 5 = 0.050s minimum answer
