RS-485 Basics
• “Recommended Standard” jointly published by Telecommunications
Industry Association (TIA) and Electronic Industries Alliance (EIA).
• Defines the electrical characteristics of interface circuits (line
drivers/transmitters and receivers) used for serial communications
over a multipoint network. Examples include:
– Signal amplitude
– Input sensitivity
– Input impedance
• Does not define:
– Cabling
– Connectors
– Data protocol
What is RS-485?
• Balanced interface (two signal lines whose voltages are the inverse of
one another)
– Increases noise immunity and decreases emissions
• Multipoint, bi-directional communication on a single pair of wires
– Lower cabling costs
• Large differential signal (>1.5V), large common-mode range (-7 to 12V)
– Allows for communication over long distances and with large
ground potential differences
• Can achieve signaling rates up to 50 Mbps
– Suitable for a wide array of applications
Why is it used?

The resistor divider network comprised of R2 and R3:
1. Biases the receiver input relative to the local VCC and ground, allowing
the receiver to operate without a ground wire.
2. Attenuates the voltages appearing at the A and B terminals (which may
range from -7V to +12V) to operable levels between VCC and ground.
RS-422
• Like RS-485, RS-422 is a differential signaling standard which defines the electrical
characteristics of drivers and receivers used to implement a balanced transmission line.
• Unlike RS-485, RS-422 is a multi-drop standard, rather than multi-point, allowing only one
driver and up to ten receivers to be connected to the bus.
• Any RS-485 compliant transceiver is compatible with an RS-422 application, though it may
not be strictly compliant with the RS-422 standard.

RS-485 Applications Tips
11
1) Use twisted pair cable.
• Z0 = 120Ω or 100Ω
2) Connect nodes via daisy-
chain.
3) Terminate unused conductors.
• RT = Z0/2
4) Terminate one end.
• RT1 = Z0
5) Apply failsafe biasing to the
other end.
6) Terminate this end.
• RT2 = [2RFS • Z0] / [2RFS – Z0]
7) Determine maximum
distance/data rate.
8) Minimize stub lengths.
• Lstub ≤ 3 •10-4 •tr •v
9) 3V and 5V XCVRs are
interoperable.
10) Use SM712 for ESD, EFT,
and surge protection.
11) Limit currents with 10Ω
pulse-proof resistors.
12) Filter signal between XCVR
and UART.
13) Isolate when GPD ≥ 7V.

• RS-232 is a single ended communication
standard for serial communication. It
conveys data over a simple unterminated
multi-conductor cable. The original
specification was designed to connect the
serial port of a computer to a modem or
other peripheral devices.
• The current version of the standard is TIA-
232-F issued in 1997

The image at left shows the
transmission of a data word using the
common “9600 – 8 – none – 1” UART
format. This means that the baud rate
is 9600 bps, the word length is 8 bits,
no parity bit is used, and one start/stop
bit is used:
• The start bit is indicated by a “0” bit
(i.e., a positive voltage)
• Next, the data is transmitted LSB
first. (This example shows
transmission of 0100001, or the
letter “A.”)
• The stop bit is indicated by a “1” bit
(i.e., a negative voltage)

Controller Area Network (CAN)
CAN (Controller Area Network)
• The CAN standard defines both a protocol and a physical layer for asynchronous, serial
communication in multi-point bus applications.
• Each node consists of a CAN transceiver and CAN controller (MCU).
• A unique driver structure results in differential signaling levels different from RS-485,
which accommodate additional features in protocol. 30
CAN Physical Layer
31
VD = CANH – CANL
Recessive when VD ≤ 0.5V Dominant when VD ≥ 0.9V
A CAN compliant driver must produce at least 1.5V across a 50Ω load.
CAN Data Frame
32
• Start of Frame – A dominant bit begins the frame and initiates arbitration
• Message Identifier – 11 or 29 bit identifier used for arbitration priority
• Control Field – Specifies the length of the data to be transmitted
• Data Field - Data
• CRC Sequence – Cyclical recovery checking
• ACK – Acknowledges the CRC status of receiving nodes
• End of Frame – Marks the end of data and remote frames
33
CAN Data Arbitration • The CAN physical layer allows for priority based arbitration based on the 11-bit identifier of each module.
– 000 0000 0000 is the highest priority identifier.
– 111 1111 1111 is the lowest priority identifier.
• During each bit of the identifier frame, each node will monitor the bus and compare the bus state with the state it is
driving.
– If the XCVR transmits a logic “1” and receives a “0”, it will stop transmitting.
– The node will attempt to access the bus again after the next inter-frame spacing occurrence.

IO-Link
IO-Link
40
• IO-Link is a serial, bi-directional, point-to-point
protocol and interface standard for sensors
and actuators in factory automation
applications.
• Standardized in IEC 61131-9, and is the first
worldwide standard for communication with
sensors and actuators.
• Standardized cabling and connectors provide
power (2 wires) and data (1 wire).
• Extends existing implementations by
providing process data, as well as
parameterization, diagnostic information, and
configuration programming.
IO-Link Operation & Features

failure, the master signals a failure to the higher-level controller.
• 7V to 36V supply voltage
• IO-Link, PNP or NPN or configurable output
• Low residual voltage of 1.75V at 250mA
• Tolerant to ±65V transients < 100µs

The TIOS101-5 EVM provides users with the ability to
evaluate TI's TIOS101x family of Digital Output (SIO)
drivers. The EVM includes the TIOS101-5 which includes an
on-chip 5-V LDO. With pin to pin compatibility throughout the
TIOS101 family, the EVM can also support the TIOS101 (no
LDO) or the TIOS101-3 (3.3-V LDO).
This design features the TIOS101 digital output driver and detect
magnetic fields and toggles its output when the magnetic field
strength exceeds a specific threshold. The design size is
optimized to fit into small cylindrical sensors and measures only
3mm x 15mm.
The TIDA-01335 builds upon the TIDA-00188 design by utilizing
the TIOL111’s small 2.5 x 3mm package and integrated EMC
protection to reduce the PCB by ~20%. This design allows
designers to easily see how TIOL111 can fit into cylindrical
sensors.

TIDA-00731: IEC ESD, EFT, and Surge RS-485 Bus Protection
EFT setup
Transient energy:
Surge >> EFT >> ESD
Transient Protection Example
TIDA-00731: IEC ESD, EFT, and Surge RS-485 Bus Protection
• TVS (Transient Voltage Suppressor): provide protection against ESD, EFT, Surge
transients. It acts as a clamping circuit to redirect any high energy pulses to ground and
away from the transceiver.
• Pulse-proof resistors: limit the residual clamping current the transceiver sees if the TVS
clamping voltage is higher than the specified maximum voltage of the transceiver bus pins.
• TBU (Transient Blocking Unit): shield the TVS diode and the RS-485 driver from AC
power cross events or large transients as well as overcurrent conditions. When the
transient current exceeds the trigger current level on the TBU device, the TBU clamps or
crowbars the current to a safe level by transitioning to a high impedance state.
• MOV (Metal Oxide Varistor): protects the TBU device from high voltage surges caused by
lightning strikes, power contact, and power induction. The MOV device has a fast turn on
time and a high current handling capability to protect the TBU, TVS and RS-485
transceiver.
• THVD1419 and THVD1429 integrate TVS diodes in SOIC-8 for IEC Surge + ESD +
EFT protections.
• Surge protected RS485 for outdoor communication blog
• Surge protected RS485 communications video

High-Voltage Stress to Bus Line Bus-Fault Protection Bus-line overvoltage faults can happen:
• Short to power supplies, Mis-wiring, Connector failure, Cable crushes, Tool mis-application
• High clamp voltage from TVS during high transient voltage
• PTC fuse (Positive Temperature Coefficient): temperature ↑ Resistance ↑ limit current flow
• SIDAC (Silicon Diode Alternating Current): after break-over, voltage is related to the current a low voltage with high
current. After high voltage is removed, SIDAC returns to non-broken over status.
Transient Protection Example: TIDA-060027: Protecting RS-485 transceivers from sustained high
voltage/electrical over-stress reference design
THVD2410 and THVD2450 support up to +/-70V bus fault & IEC ESD/EFT protections
