Ethernet Operation
The Ethernet interface supports 100Mbit/s full duplex operation only. Data is transmitted from one port
the other port with minimum delay or buffering.
The port implements "Auto MDI/MDIX" i.e. it may be connected with either a straight-though or cross-
over cable to an appropriate device such as external switch, PC or other DCE/DTE.
Two LED indicators are provided adjacent to the RJ-45 port: Green indicates Link / Data transfer and
Yellow indicates no Ethernet connection.

Data and Alarm Channel Configuration
The AMG5804A966G-DF transmit unit sends and receives data to/from an AMG5803A966-DF or
rackmount equivalent AMG5803A966G-DF receive unit. The 2 physical data interfaces RS-485, RS-
422 or RS-232 are individually selectable by the user with the slide switch mounted from the rear
panel.
There are also 8 bi-directional alarm inputs provided, each alarm input is typically connected to a
contact closure switch. Each alarm output can receive an on/off signal from an AMG5803A966-DF
and is typically used to convey contact closure status.
Data Channel Configuration
Each low speed data channel provides an RS-232, RS-422 (full duplex, four wire) or RS-485 (half
duplex, two wire) interface defined by the corresponding mode switch inside the enclosure. Every data
channel as shipped from the factory is set up for RS-485 operation unless otherwise requested.
The data input for both the RS-485 and the RS-422 modes detects a tri-state input condition by
monitoring the differential voltage level across the input. A differential level below 600mV positive or
negative will be detected as a tri-state condition. A level above 600mV positive or negative will be
detected as a logic 1 or logic 0 respectively. It is important therefore to terminate the RS-485 bus or
the RS-422 input bus using 120Ω if a pre-bias is present on the RS-485 or RS-422 bus.
A large number of third party equipment manufacturers apply a pre-bias on their RS-485 bus. This pre-
bias is applied by pulling one arm of the RS-485 bus high (+5 volts) and the other arm low (0 volts)
using high value resistors within the third party equipment. In order to ensure that the AMG equipment
detects a tri-state condition, then these resistors should have a value above 5kΩ. If the third party
bias resistors are less the 750Ω the bus can be multiple terminated as required to ensure that a tri-
state level is detected.
The system detects a tri-state input condition on the data channel bus when in RS-485 or RS-422
mode.

The interface mode RS-232, RS-422 or RS-485 of each data port Data 1-4, is selected with the
corresponding external slide switch D1-D4. The actual number of data channels provided on the unit
depends upon the AMG model.
Internal 120Ω termination resistors across IN+ and IN- inputs may also be applied when in RS-422 or
RS-485 mode using internal DIP switches P0-P3 on the main PCB inside the enclosure. P0-P3 may

be accessed by removing the 2 fixing screws in the rear panel and sliding the PCB out of the
enclosure.
For clarity, in the 3 examples shown below all 4 data ports D1-D4 are terminated the same, but each
data channel may be configured & terminated independently as required. The 3 examples shown are
RS-232 (no termination), RS-422 (120Ω) or RS-485 (120Ω).
Alarm Channel Configuration
The AMG5804A966G-DF provides 8 bi-directional contact closure inputs / alarm outputs. Each
ALARM IN input is via an internal 10kΩ series resistor with a 47kΩ pull-up resistor to the internal +3V3
supply.
Each ALARM OUT output can receive an on/off signal from an AMG5803A966-DF and is typically
used to convey contact closure status. Each alarm output is NPN open collector, maximum load 50mA
/ 24Vdc.
Alarm Channel Circuit
The output of each alarm channel is an NPN open collector transistor circuit, with an absolute
maximum rating of 1A / 60V. There is a common GND for all alarm channels.

The alarm output circuit is designed for low dc voltage / low current operation and has minimal internal
protection. If an alarm output is used to drive an external relay circuit, the external crcuit MUST include
a protection (flyback) diode connected across the relay to prevent the high voltage generated from a
back EMF causing damage due to the AMG output transistor.

Audio Channel Connections
The AMG5804A966G-DF provides six bi-directional audio channels.
Each audio channel input is a balanced pair and the impedance can be configured as 56kΩ or 600Ω.
The input impedance of each audio channel is individually selected using the DIL switch on the front
panel.
If an audio input is single ended or ground referenced input rather than a differential (balanced) input
pair, the Audio IN- signal should be connected to one of the GND pins available on the 37way D-type
connector. These GND inputs are common to all audio channels.
Echelon FTT-10A Data Channel Configuration
The AMG5804A966G-DF provides 2 Echelon FTT-10A Data channels.
The GND connection associated with any Data signal signal should be connected to one of the GND
pins available on the 37way D-type connector. These GND inputs are common to all audio / data
channels.
