3.2.2 Location Engine IP Address
The default Reader configuration assumes that the location engine IP address is the first IP address in
the subnet. For example, if the acquired IP lease is 10.25.67.100 and the subnet mask is 255.0.0.0, then
the Reader software assumes the location engine IP address is 10.0.0.1. The Reader may also be
configured with a static location engine IP address. The location engine IP address may be specified
through the RS-232 interface and through the Ethernet interface.
3.2.3 Reader Port Assignments
The Reader software listens for Tag packets and sends one Time of Arrival (TOA) packet over the
Ethernet for every Tag packet that is received successfully. The TOA packets are sent as UDP packets
to the location engine's IP address at port 11000. This software also listens for commands on TCP port
11001. The formats for all Ethernet packets are discussed in a following section.
3.3 RS-232 Interface
3.3.1 RS-232 Port Connection Parameters
The Reader RS-232 connection parameters are as follows. Connection to the Reader RS-232 requires a
PS/2 to DB9 adapter.
Baud Rate: 115,200
Data Bits: 8
Parity: none
Stop Bit: 1
Flow Control: none
3.3.2 Terminal Connection Login
Log in to the Reader with username plus and password timedomain.
3.3.3 Terminal Connection Commands
The terminal connection may be used to configure the Reader IP address settings and location engine IP
address. Changes made with the following utilities are written to flash memory.
changeIp starts a command-line menu for configuring the Reader IP address. Menu option 1
configures the Reader to obtain an address automatically from a DHCP server. Menu option 2 allows
the user to set the Reader to a static IP address, subnet mask, and gateway. Pressing Enter exits the
changeIp application without changing the Reader’s IP configuration.
solverIp starts a command-line menu for setting the IP address of the location engine. Menu option 1
configures the Reader to generate the location engine IP address automatically. Menu option 2 allows
the user to set the location engine IP address. Pressing Enter exits the solverIp application without
changing the location engine IP address.
