Appendix 10BASE-T/100BASE-TX Ethernet Interface Software specifications Basic communication protocols • IP, ARP, ICMP, UDP, TCP: Basic communications protocols for various functions (used by higher-level protocols below) Printing communications protocols • LP, LPR: Transfers printing data. • TCP socket port: Transfers printing data and printer status with direct socket communications (bi-directional). Protocol for obtaining status and setting • HTTP: Displays module status and makes setting with the Web browser. • SNMP: Obtains status and/or sets the module or printer with the dedicated/commercial MIB tool. • ENPC: Obtains status and/or sets for the module and printer.
Automatic IP Address Assignment Protocols Automatic IP addressing is executed in order shown in the table below. If DHCP is disabled or IP addressing for DHCP fails, then IP addressing for the next protocols is executed. If APIPA is disabled or IP address cannot be obtained, the internal setting parameters are used. Internal parameter settings • ENPC protocol: Epson provides a dedicated utility that makes miscellaneous setting with the ENPC protocol. Internal parameter settings can be changed with the following: • HTTP browser: An HTTP browser can make setting when connected to the module. • arp commands and ping commands (Only IP address is settable.):
This function is available only when it has been enabled. The setting can be made only from a host PC that supports both arp and ping commands and is in the same segment as the module. 87 Protocol Order Application DHCP 1 Obtains IP address. APIPA 2 Assigns IP address. Manual setting 3 Uses the internal parameters.
