====Cables====

+

----

+

There are two types of RS232 serial devices: '''DTE''' and '''DCE'''. DTE typically refers to the serial port on a PC or terminal, while DCE refers to communication devices. Connectors mounted on DTE are likely to be male, and those mounted on DCE are likely to be female.

+

This device is DCE and has a female connector.

+

----

+

To connect a standard DTE device, use a straight-through Female/Male RS232 cable:

−

[[File:~~Networking_rutos_manual_serial_utilities_add_new_instance_default_{{{default}}}_v1~~.~~png|border|class=tlt-border~~]]

+

[[File:Services rs232 connector female male.PNG]]

−

~~Then, click the Edit button next to the instance~~:

+

See straight cable pinout below:

−

[[File:~~Networking_rutos_manual_serial_utilities_edit_config_default_{{{default}}}_v1~~.png|~~border|class=tlt-border~~]]

+

[[File:Straight cable pinout v2.png|400px]]

−

~~This manual page provides an overview~~ of the ~~Serial Utilities page in~~ {{{~~name~~}}} devices.

+

----

+

To connect another DCE device to RUT/TRB, a Null-modem (crossed) Male/Male cable should be used:

+

[[File:Male male rs232 cable.jpg]]

+

See straight crossed cable pinout below:

+

[[File:Straight crossed rs232 cable pinout v2.png|400px]]

+

----

+

Maximum cable length is 15 meters or the cable length equal to a capacitance of 2500 pF (for a 19200 baud rate). Using lower capacitance cables can increase the distance. Reducing communication speed can also increase maximum cable length.|}}

====Maximum data rate vs. transmission line length====

+

----

+

The RS485 standard 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 (10 Mbps) is limited to a transmission length of about 12 meters, while a distance up to 1200 meters can be achieved at 100 Kbps. A rough relation between maximum transmission length and data rate can be calculated using this approximation:

+

[[File:Services rs485 formula.PNG]]

+

Where:

+

<ul>

+

<li>Lmax - maximum cable length in meters.</li>

+

<li>DR - maximum data rate in bits per second.</li>

+

</ul>

+

Twisted pair is the preferred cable type for RS485 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 (120 Ω each) 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:

+

[[File:Services rs485 4wire_v2.PNG]]

+

Example 2-wire network electrical connection: to enable a 2-wire RS485 configuration you need to connect D_P to R_P and D_N to R_N on the device’s RS485 socket. Termination resistors are placed at each cable end (120 Ω each):

==Modem Control==

+

{{#ifeq:{{{modem}}}|1|==Modem Control==

The Modem serial type is used to manage modem functionality which could be accessed using shell interface. For this purpose you may want use CR/LF (Carriage Return, Line Feed) capable applications like PuTTY on Windows and microcom, minicom, cutecom or similar applications on Linux.
