NOTE: By setting SW5 ON to enable download, the default parameters will first be restored and saved to the non-volatile memory, erasing the previously stored communication and operating parameters. These parameters will take effect after a hard reset or a power-on reset. A hard reset is invoked by depressing the hard reset switch, holding for one second, and releasing. The hard reset switch is shown in Figure 35.

The baud rate, as determined by SW1 and SW2, only applies to the COM1 serial interface. When the optional Ethernet interface is selected by setting SW4 to the “ON” position, the baud rate is set automatically for Ethernet communication, and SW1 and SW2 are ignored.

The communication parameters for COM2 can only be changed by menu configuration. Because COM2 is an auxiliary interface, the default parameters for COM2 are sufficient for the infrequent use of this interface, and should not be changed. For example, if a user changes to a faster baud rate on COM2, a problem can occur when trying to re-establish communication at a later date. Because there is no obvious indication that the baud rate has been changed, the next operator would likely try to reconnect at the default, 9600 baud, and would be unable to connect. The quickest way to re-establish communication is to set SW5 ON and reset, then set SW5 OFF and reset again. This will overwrite all the communication parameters on COM2 and allow the operator to connect, but it also overwrites all the information for COM1, as well as the RFID parameters. The best practice is always to use the defaults for COM2.

4.2 Optional Ethernet Interface

As an alternative to the RS232 and RS422 interfaces, COM1 of the LRP2000 can be configured to communicate on Ethernet networks. This option can be fulfilled by Escort Memory Systems' Ethernet module. To configure the LRP2000 COM1 to communicate via Ethernet, set SW4 ON. This correctly sets all communication parameters between the Ethernet module and the controller. Section 4.3 details the configuration of the Ethernet module for network

4.3 Configuring the Ethernet Module for Network Communication

Once wired correctly, the Ethernet Module must be configured to communicate on a network of computers and peripherals. This can be accomplished by connecting the controller's RJ-45 jack directly to the NIC on a PC through a crossover cable. Alternatively, the Ethernet module can be connected directly to a router of a LAN. This can cause serious problems if another device on the network has the same IP address.

The Default IP Address

The default IP address of all LRP2000 controllers is set to 192.168.253.222 at the factory. In order to avoid IP address conflicts, the unit must be assigned a unique IP address before it is installed for operation. For configuration, the Ethernet module provides an interactive web page to update addresses.

NOTE: If connecting directly from the NIC on a PC, under some operating systems with dynamic IP allocation, it is necessary to fix the IP address of the PC to ensure that the IP address will not change during configuration.
