Communications information (continued)
Network Connections
The T4220, M4240/AP110, and M4240/AP210 terminals can connect over a
network connection via a local area network.
The T4220 connection is on the back of the terminal (white NET port).
The M4240 connection is on the front panel of the AP110/210 Access Point
(white NET port).
The following points should be noted:
Your terminal will be pre-configured for use on standard networks featuring
DHCP (automatic allocation of IP addresses). In the unlikely event that your
network does not have this feature, please call the helpdesk for assistance.
Any security features (such as MAC address filtering in your router) need to have
the terminal added to their list of allowable MAC addresses. The MAC address for
the T4220 is found on a label on the underside of the terminal, and that for the
AP110 and AP210 on the underside of the access point.
Please ensure the specific IP addresses and TCP Ports provided by your terminal
supplier are not blocked by a network firewall.
GPRS Connections
The T4230 and M4230 communicate through the mobile telephone network
using a GPRS connection. A SIM card (pre-installed by Hypercom) is used
to control this connection.
The following points should be noted:
Do not remove the SIM unless instructed by the helpdesk. Unauthorised
removal of the SIM may render your terminal inoperable and/or may result in
late/non-payment of funds into your account.
Hypercom reserves the right to charge for unauthorised use of your SIM.
Hypercom may charge an administration fee for misuse or replacement of a lost
or blocked SIM.
