I. SensorNet Protocol

SensorNet is a two-wire serial data protocol that provides half-duplex, multi-drop, differential communications.

Cable segment: Includes all of the electrically connected wire between all of the multi-drop devices of a communications topology. It does not include the wire beyond the repeater devices.

Communication Source: The device that is managing the communications or polling other devices, also referred to as host or primary. On a cable segment that does not have a direct communications source it is the repeater that is repeating the data from the host or primary.

Repeater: Any device that will amplify the signal.

Device: Any unit that is attached to a network.

SensorNet Protocol Key Points

1. Only terminate a communications source or network device if it is at the end of a cable or end-of-line. Each SensorNet device has a termination switch or jumper. Terminating the devices at the ends of the cable prevent the signals from reflecting back along a cable. Proper termination makes

communications more reliable. J-Box and distribution panel outputs renew or amplify the signals,

so they are considered communications sources. In daisy chain and backbone networks, they are

considered end-of-line and should be terminated. In star networks, they are not considered end-of-

line and should not be terminated. J-Box and distribution panel inputs are considered network

devices. Terminate them only if they are end-of-line.

2. No more than four repeaters are allowed between any two devices connected with cable segments

through repeaters. Devices include SensorNet Domes, Touch Trackers, ADMPCPU, SensorNet

I/O units, SensorNet to RS-422 converters, SensorNet Distribution Panels, SensorNet links for

American Dynamics MPLT / MP48 / VM96 / AD168 switches, SensorNet J-Boxes, and fiber optic

transceivers that contain repeaters between their separate output ports.

This 4-repeater restriction includes devices that are not on the same cable segment or leg of the

network. Data packet collisions resulting in loss of data may occur between out-bound (from the

communications source) and in-bound (to the communications source) communications.

3. Signal repeaters (J-Boxes, Distribution Panels) should only be used when cable distances exceed

the maximum allowed or when noise is an issue. SensorNet devices can operate at signal levels

from 0.3V to 5V, but 1V to 5V is recommended.

4. If shielded cable is used, signals may rapidly decline as more devices are connected or as the

cable length increases. As a result, the maximum length is less for shielded cable, and signal

integrity is reduced; therefore they are not recommended, and should only be used for short

distances when unavoidable. Problems have been experienced. The shield should be connected

at the communications source end only.

5. Attach network devices in stages. Check that their response is correct so you can correct the

problem before continuing with the installation. Use ping tests to measure failure rate or operate

the dome to verify proper operation.

6. No more than 32 devices per cable segment. With a daisy chain or backbone network, a cable

segment starts at the first network device on the cable and ends at the last network device on the

cable. The network device at the start or end of the cable may be a communications source. A star

network supports up to four branches. All four branches are considered one cable segment for

determining the cable length. However, the network device at the end of each of the four branches

should be terminated to ensure reliable communication.



7. If a repeater must be used, place the repeater at the 66% distance point along the cable

(measured from the source). This will ensure that there is a reliable signal at the input to the

repeater.

8. SensorNet can be used with Star, Daisy Chain, or Backbone networks.

9. SensorNet connections are not polarized.

Advantages of SensorNet Protocol

1. The connections are not polarized and the two wires can be connected in any order.

2. Firmware can be uploaded to domes using a PC with a USB-to-SensorNet module (ADACSNET), an MP48 Plus system, or an ADTT16E controller.

3. A ping test can be used to determine the reliability of the network.

4. Remote manual dome reset command from console.

5. SensorNet outputs are transformer coupled to provide 2000V galvanic isolation, to prevent ground loops, and to prevent conducted discharge currents from flowing through the system.

6. SensorNet outputs incorporate TVS (Transient Voltage Suppression) surge protection devices and drivers that can withstand 2000V ESD level surges.

7. SensorNet outputs are protected with PTC (Positive Temperature Coefficient) self-resetting fuses to guard against inadvertent wiring connection to up to 30Vac, class 2, LPS power.

II. RS-422 Protocol

Duplex RS-422 uses four wires to provide duplex, multi-drop, differential communications.

Advantages: No termination required, allows more repeaters per line.

Disadvantages: Slower speed, 4-wire polarized, less noise immunity.

Simplex RS-422 uses two wires to provide simplex, multi-drop, differential communications.

Advantages: Two wires, no termination required, allows more repeaters per line.

Disadvantages: Slow speed, one-way communications, polarized wiring, less noise immunity.

Network Topologies: Daisy Chain, Backbone.

RS-422 Protocol Key Points

1. RS-422 does not require terminations.

2. If a repeater must be used, place the repeater mid-way along the cable. This will ensure that there

is a reliable signal at the input to the repeater.

3. More than four repeaters are allowed between any two devices on the network. Devices include

Domes, RS-422 converters (RCSN422), RS-422 Distribution Panels, RS-422 links for American

Dynamics MPCPU / MP48 / VM96 / AD168 switches, and RS-422 J-Boxes.

4. Signal repeaters (J-Boxes, Distribution Panels) should only be cascaded when cable distances

exceed the maximum allowed or when noise is an issue.

5. Ground the shield wire at the source device only. This will prevent ground loops.




problem before continuing with the installation.

7. No more than 10 devices per cable segment. With a daisy chain or backbone network, a cable


cable. The network device at the start or end of the cable may be a communications source.

8. RS-422 can be used with Daisy Chain or Backbone networks only.

9. RS-422 connections are polarized. Care must be taken to connect the correct wires to the

appropriate device terminals.

III. Manchester Protocol

Manchester uses two wires to provide simplex, multi-drop, differential communications.

Advantages: Moderate speed, high noise/surge/static immunity.

Disadvantages: Polarized wiring, not high speed, drives three devices. Proper termination required for reliable communications.

Network Topologies: Daisy Chain, Backbone.

Manchester Protocol Key Points

1. Only terminate a communications source or network device if it is at the end of a cable or end-of-line. Each device has a termination switch or jumper. Terminating the devices at the ends of the cable prevent the signals from reflecting back along a cable. Proper termination makes

communications more reliable. Distribution panel outputs renew or amplify the signals, so they are

considered communications sources. In daisy chain and backbone networks, they are considered

end-of-line and should be terminated. Distribution panel inputs are considered to be network

devices. Terminate them only if they are the end-of-line.

2. If a repeater must be used, place the repeater mid-way along the cable. This will ensure that there

is a reliable signal at the input to the repeater.

3. No more than three repeaters are allowed between any two devices on the network. Devices

include Domes, code converters, Manchester Distribution Panels, and Manchester links for

American Dynamics MPCPU / MP48 / AD168 / AD2150 switches.

4. Signal repeaters (Distribution Panels) should only be cascaded when cable distances exceed the

maximum allowed or when noise is an issue.

5. Ground the shield wire at the source device only. This will prevent ground loops.

7. No more than 3 devices per cable segment. In a daisy chain or backbone network, a cable


cable. The network device at the start or end of the cable may be a communications source.

8. Manchester can be used with Daisy Chain or Backbone networks only.

9. Manchester connections are polarized. Care must be taken to connect the correct wires to the

appropriate device terminals.

DOME 1-16DOME 17-32NOTES(1):

There are 2 separate Sensornet

ports on the ADMPLT -- Port A &

Port B.

The matrix embedded configuration

menu determines which camera

address is routed to which

Sensornet port.

By default, ALL of the cameras are

set to AD Up-the-Cable (UTC)

protocol and must be reconfigured

for Sensornet Port A or Port B

routing.

If conversion of both ports to RS-422

is necessary, a second RCSN422

module is required.

NOTE(2): If there are

MINIDOMEs on the RS-422

network, set the device address

to 16. For SPEEDDOME or

later models, set the device

address to 32.

Sensornet Port A

NOTES(1):

There are 2 separate Sensornet ports on

the ADMPLT -- Port A & Port B.

The matrix embedded configuration

menu determines which camera address

is routed to which SensorNet port.

By default, ALL of the cameras are set

to AD Up-the-Cable (UTC) protocol and

must be reconfigured for SensorNet Port

A or Port B routing.

If conversion of both ports to RS-422 is

necessary, a second RCSN422 module

is required.

Note: When using the Manchester

protocol, the maximum number of

domes that may be daisy chained is

3. If more than 3 domes are required,

the ADACSNETD (Manchester

distribution panel) is needed.

DIAGRAM #19

This is a backbone / daisy chain topology with 3

devices on one cable segment (key points #7 and

#8).

Device #1 is terminated because it is at the end of

the line (key point #1).

Devices #1, #2, #3, and #4 are connected

maintaining proper signal polarity (key point #9).

No Manchester repeater is used (key point #4).

Total Manchester cable distance is 170 meters

(~600 feet).
