23. Appendix 6: M4221 Ethernet Module
23.1. Overview
The M4221 Ethernet module provides IP (internet protocol) connectivity to the
indicator. The information in this appendix only applies to indicators fitted with this
module.
23.2. Network Configuration
After installing the module, and connecting it to the network it is necessary to
configure the network settings for the module. These settings may be automatically
configured from your network via DHCP (Dynamic Host Configuration Protocol), or
may need to be set manually. Contact your network administrator for settings
appropriate to your network. The DHCP setting, IP address, network mask, default
gateway and DNS servers are configured from the indicator via the ETH.HW menu
(Section 12.2.3 on page 61). Additionally a host name & DHCP client ID may be
optionally configured from the Module web page.
23.3. Viewing the Current Configuration
The Acc menu provides access to the current IP configuration of the module. Refer
to Section 5.15 on page 35.
23.4. Services
The M4221 provides a number of services via the network, including a configuration
web page and two TCP ports providing access to the indicators’ serial ports SER.3A
and SER.3B.
23.4.1. TCP Sockets
SER.3A can be accessed via TCP port 2222 on the module. This port allows only
one simultaneous connection as it is bi-directional
SER.3B can be accessed via TCP port 2223 on the module. This port allows up to
10 simultaneous connections, as it is transmit only (data is sent from the indicator to
the PC).
As with other serial modules, it is necessary to configure a function (networking,
printing or auto-outputs) on the indicator to communicate via SER.3A or SER.3B.
The Viewer software can be used to test the connection to the indicator. This
requires Viewer version 1.44+. Select a TCP connection from the connection
settings dialog, and enter the indicator IP address or hostname. The TCP port
should be set to 2222.
23.4.2. Web Interface
There is a Web page provided by the module. This can be accessed by determining
the IP address from the Acc menu, and then entering the following into your web
browser: http://<module_ip_address>/. The default username for the module web
page is “admin”, and the default password is “PASS”.
