RFI-148 & RFI-900 High Output Power Paging Transmitters User Manual Page 25 of 134
These statistics may be useful in troubleshooting. For example, Rx framing errors may indicate that the serial
port configuration does not match the serial port configuration of the link partner.
4.2 Ethernet Operation
4.2.1 Overview
The paging transmitter has one 10BASE-T/100BASE-TX Ethernet port. Auto-negotiation of link speed is
supported, including duplex mode. There is also a software override for forcing the parameters of the link.
4.2.2 IP Addressing
The paging transmitter supports IPv4. The paging transmitter may have a statically assigned IP address or
obtain an IP address as a DHCP client.
A static IP address may be configured with a single static address. A subnet mask and default gateway may be
configured to allow communication across sub-networks.
The paging transmitter may act as a DHCP client. This allows a DHCP server to assign an IP address to the
paging transmitter. By default, the DHCP client is enabled and the hostname of the paging transmitter is of the
form “rfi-serial_number” where serial_number is the factory assigned serial number of the unit. If the unit
does not receive an IP address from the DHCP server, the IP interface will not work.
4.2.3 Statistics
Both IP and Ethernet packet statistics are independently recorded and presented as combined figures for all
active data streams since the transmitter was last powered-up. A power-cycle of the transmitter clears this data.
4.3 Transmitter Operation
4.3.1 Transmit Power
The RFI-148/900250 supports transmit power from 20 to 250 Watts in 1 Watt increments. The Canadian
release of the RFI-148 250 is software limited from 20 to 110 Watts in 1 Watt increments.
POWER FOLDBACK
The power foldback is a configurable percentage which calculates the power to foldback to when the scale
transmit power fault action is latched. For example, for a transmit power of 250 W and a power foldback of
50%, the transmitter will transmit at 125 W when the scale transmit power fault action is latched. See section
5.2.1 for more information on fault actions.
4.3.2 Channel Selection
The RFI-148/900250 has up to sixteen radio channels. Each channel represents a transmit frequency.
