<!------------------------DEVICE----------------------->
RS232 and RS485 functions are designed to utilize available serial interfaces of the router. Serial interfaces provide a possibility for legacy devices to gain access to IP networks. This chapter is an overview of the RS232/RS485 functions in RUT routers.

RTS and CTS are turned OFF and ON from alternate ends to control data flow, for instance when a buffer is almost full <br> '''Xon/Xoff''' - software handshaking. The Xon and Xoff characters are sent by the receiver to the sender to control when the sender will send data, i.e., these characters go in the opposite direction to the data being sent. The circuit starts in the "sending allowed" state. When the receiver's buffers approach capacity, the receiver sends the Xoff character to tell the sender to stop sending data. Later, after the receiver has emptied its buffers, it sends an Xon character to tell the sender to resume transmission</td>

===Maximum data rate vs. transmission line length===
  −
----
  −
RS-485 standart can be used for network lengths up to 1200 meters, but the maximum usable data rate decreases as the transmission length increases. A device operating at the maximum data transfer rate (10Mbps) is limited to a transmission length of about 12 meters, while the 100kbps data rate can achieve a distance up to 1200 meters. A rough relation between maximum transmission length and data rate can be calculated using this approximation:
  −
 
  −
[[Image:Services rs485 formula.PNG]]
  −
 
  −
Where Lmax is the maximum transmission length in meters and DR is maximum data rate in bits per second.
  −
 
  −
Twisted pair is the prefered cable type for RS-485 networks. Twisted pair cables pick up noise and other electromagnetically induced voltages as common mode signals, which are rejected by the differential receivers.

===2-Wire and 4-Wire Networks===
  −
----
  −
Below is an example of a 4-wire network electrical connection. There are 3 devices shown in the example. One of the devices is the “master” and other two are “slaves”. Termination resistors are placed at each cable end. Four-wire networks consists of one „master“ with its transmitter connected to each of the “slaves‘” receivers on one twisted pair. The “slave” transmitters are all connected to the “master” receiver on a second twisted pair.
  −
 
  −
[[Image:Services rs485 4wire.PNG]]
  −
 
  −
Example 2-wire network electrical connection: to enable a 2-wire RS-485 configuration on a Teltonika router, you need to connect D_P to R_P and D_N to R_N on the device’s RS-485 socket. Termination resistors are placed at each
  −
cable end.

===Termination===
  −
----
  −
'''When to use (place jumper)'''
  −
 
  −
Termination resistor, equal in resistance to cable characteristic impedance, must be connected at each end of the cable to reduce reflection and ringing of the signals when the cable lengths get relatively long. Rise time of the RUT955 RS-485 driver is about 5 ns, so the maximum unterminated cable length is about 12 cm. As transmission line cables will always be longer than 12 cm, termination is mandatory all the time if RUT955 is located at the end of the cable.
  −
 
  −
'''When not to use (remove jumper)'''
  −
 
  −
If your RS-485 consists of more than two devices and the RUT955 router is located not on the end of the line but, for example, in the middle, RUT955 termination resistor needs to be disabled. In this case, place termination at other devices which are situated at the ends of the line.
  −
 
  −
'''How to enable termination'''
  −
 
  −
120 Ω termination resistor is included on the RUT955 PCB and can be enabled by shorting contacts (shown in the picture below), placing 2.54mm pitch jumper:

===Number of devices in an RS-485 Network===
  −
----
  −
One RUT955 RS-485 driver is capable of driving a maximum of 32 receivers, provided that the receiver input impedance is 12 kΩ. If receiver impedances are higher, the maximum number of receivers in the network increases. Any combination of receiver types can be connected together, provided their parallel impedance does not exceed RLoad > 375 Ω.

==Modes of different serial types in RS232 and RS485==
  −
 
  −
===Console===
  −
----
  −
In this mode the serial interface set up as a Linux console of the device. It can be used for debugging purposes, to get the status of the device or to control it.
  −
 
  −
===Over IP===
  −
----
  −
In '''Over IP Serial''' type the router provides a connection to a TPC/IP network for the devices connected via serial interfaces.

===Modem===

----
  −
With Modem Serial type, the router imitates a dial-up modem. Connections to TCP/IP networks can be established using AT commands. The connection can be initiated by the device connected via serial interface with an ATD command: ATD <host>:<port>. If Direct connect settings are specified, the connection to the server is always active. Data mode can be entered by issuing the ATD command. Incoming connections are indicated by sending a RING to the serial interface.

The way this field is named and its function depends on the value of the ''Slave ID configuration'' field. <br> A range of IDs can be specified by placing a '''hyphen''' ('''-''') between two integer numbers. For example, if you permitt slave IDs in the range of 10 to 20, you would specify it as: '''10-20''' <br> You can also specify multiple values that are not connected in a range using '''commas''' (''','''). For example, to specify 6, 50 and 100 as permitted slave IDs, you would have to use: '''6,50,100'''
