SECTION 5. NETWORK INTERFACE
The Network interface allows for the following:
• Transfer of images to a host using FTP (file transfer protocol)
• Telnet communication between the MICR and a host
• Configuration of Ethernet parameters from DHCP (Dynamic Host Configuration Protocol) or fixed
(nonvolatile) MICR memory
• Log in to network using modem and PPP. Configuration of some parameters using IPCP.
NETWORK IMAGE FTP
Images can be transferred to a host by using FTP. This is accomplished by using the image transfer
commands TI and SF in coordination with the SWE configuration command. See the documentation that
describes these commands for more details.
NETWORK TELNET COMMUNICATIONS
In addition to RS232 communications, a host can communicate with a MICR using Telnet. During the
Telnet session the host acts as the client and the MICR is considered the server. The host is responsible
for establishing the Telnet connection and only one host can connect to the MICR at any one time. Using
Telnet, the host can send commands and receive responses as well as MICR and MSR data depending on
the configuration.
ETHERNET OR MODEM NETWORK CONFIGURATION
The MICR needs a number of parameters to be set up in order to communicate using the Network
interface. Ethernet parameters include the MICR IP Address, MICR IP Mask, Gateway/Router and DNS
IP Address. Modem parameters include Phone number, User ID and Password. Both interfaces use FTP
IP Address, FTP User ID, FTP Password, and FTP File Directory. These parameters are generally loaded
when the MICR powers up or is reset. These parameters can be obtained from nonvolatile memory within
the MICR (fixed), or optionally with the Ethernet interface using DHCP, or a combination of both
methods. Note that in order to obtain any parameter using DHCP, the MICR IP Address must be obtained
by DHCP. It is critical that the MICR is configured properly in order to obtain these parameters correctly.
See the documentation that describes these parameters for more details.
NETWORK CONFIGURATION PROPERTIES
The properties needed to configure the unit for network communications are:
PR0 – PR11 and PR13 – PR19. See Section 6.
