E Series Ethernet Radio – User Manual
Version 08-10
Part E – Getting Started- ER45e
Power Supply Requirements
The ER45e Ethernet modem is designed and calibrated to operate
from a ltered 13.8Vdc regulated supply, but will operate from a
10-30Vdc (11-16Vdc for EB45e & EH45e) range. See Section L -
Specications for more details on power supply requirements
Caution: There is NO readily serviceable internal fuse for
an EB45e or EH45e, and therefore they both MUST be
externally fused with a fuse and fuse holder (EB45e: 5
amp fast-blow fuse, EB45e(20W): 8 amp fast blow fuse,
EH45e: 1 amp slow blow fuse).
The ER45e is designed to self protect from permanent damage if
the voltage exceeds 30VDC. The radio may need to be returned for
service if this occurs. The ER45e remotes have an in Series Diode
to protect against applied reverse polarity.
The radio modem can also be damaged if there is any potential
difference between the chassis-ground, RS232 signal ground,
power (-) input, or antenna coaxial shield. Before connecting any
wiring, ensure all components are earthed to a common ground
point.
Connect the antenna, RS 232 plug and LAN plug BEFORE
applying power to the unit.
Lastly, before inserting the power plug, please re-check that
the polarity and voltage on the power plug is correct using a
multimeter.
TVIEW+ Management Suite
Radio Conguration
This TVIEW+ Management Suite allows a number of features
including: Conguration (Local - serial, or Remote - over-the-air),
Remote Diagnostics Facilities and Firmware Upgrades.
The conguration wizard can be used to provide Quick Start
generic templates for the types of systems architecture you wish
to employ.
Example: Local conguration session –
1 Attach the programming cable from the PC to the System
Port of the radio
2 Launch TVIEW+ & Select “Programmer”
3 Select “Read” the radio
4 Change the conguration as required
5 Select “Write” the parameters back to the radio
Refer to Parts I & J – TVIEW+ Management Suite for detailed
operation of advanced features.
Activating the Transmitter
In most systems, the transmitter by default is controlled
automatically by the radio when it has data to transmit.
In some systems, such as full duplex point-to-point links or full
duplex point-to-multipoint base stations, it is desirable to run the
transmitter all the time (hot keyed).
Two mechanisms are provided to do this:
• The radio modem can be congured to transmit
continuously whenever powered, or
• The radio modem can be congured to transmit whenever
an external RTS signal (Pin 7) is applied to one (or either)
user ports. (To simulate an external RTS input, loop pins 6
to 7).
To operate in these modes, the radio must be congured via the
programming software.
Caution: When the radio is congured to transmit
continuously, ensure an RF load is present BEFORE
applying power to the unit.
NOTE: The ER45e has a readily serviceable internal
fuse Trio Part number: Part No. SM%FUSSQ5A) 5A
