Step 4b 
(MEI only) 
Click on the desired duplex mode selector.  Select Full Duplex to always enable 
transmit and receive drivers.  
Select 
Half Rx to enable the transmit 
drivers only when the SDS is 
transmitting; receivers will always be 
enabled.  
Select Half Rx Tog to enable the transmit 
drivers and to disable receivers only 
when the SDS is transmitting.

Step 4c 
(MEI only) 
Click on the desired connector setup.  
Select Loopback All to internally loopback 
RTS and CTS in the SDS. AuxIn and 
AuxOut are looped at the connector.  
Select Modem Control to send RTS on 
the AuxOut signal and to receive CTS on 
the AuxIn signal.

Select 2- or 4-wire communication.  
Select 2-wire to use the transmit pair for 
both transmit and receive in RS-422/485. 
Select 4-wire to use a separate pair of wires 
for transmit and receive in RS-422/485.

Repeat the steps above for each port you 
need to configure and then press Save to 
implement all of your changes. 
Close and re-open the port to activate 
your changes. 
That’s it! You’re done. Your SDS is 
configured for the Raw TCP operating 
mode. 
Setting Raw UDP operating mode parameters 
Raw UDP is mainly used to broadcast messages over a network. It is 
a connectionless protocol that offers a direct way to send and receive 
datagrams over an IP network but provides very few error recovery 
services. UDP applications must generally be willing to accept some 
loss, errors, or duplication. Most UDP applications do not require 
reliability mechanisms and may even be hindered by them. If your 
application requires a high degree of reliability, you should use a 
protocol such as TCP. 
Note: In Raw UDP, your SDS 
can send messages to multiple 
receivers simultaneously. 
 
UDP provides no guarantees for message delivery and a UDP sender 
has no way of telling the status of its messages once it sends them 
onto the network. For multicast packages, unlimited propagation of 
UDP packets through routers is prevented by the Time To Live (TTL) 
scheme. Each router decrements a packet’s TTL value and only 
forwards those packets whose TTL value is greater than the 
threshold configured on the router.
