Connections
This section tells you how to connect the terminal communication and option wiring. The
battery backup option, if present, is mounted in the terminal base. Your terminal may not have
these options.
Standard Ethernet Connection
When using an Ethernet connection, the Maximus terminal can be located at any point in a
TCP/IP Ethernet 10/100BASE-T network, providing the single segment length from the
network hub or switch to the terminal does not exceed 328 wire-feet. A typical topology for
the Maximus terminal in an Ethernet 10/100BASE-T network is a star configuration.
For Ethernet communication applications, we recommend using CAT-5 unshielded twisted-pair
high-speed data transmission cable with RJ45 plugs wired according to the EIA/TIA 568B
standard. One end of the RJ45-terminated cable plugs into the Maximus Ethernet
communication port or PoE option card, while the other end plugs into the network hub.

RS232 Connection
The Maximus options include an RS232 serial module with either an RJ11 or RJ45 socket.
ATS recommends using its modular telephone type data cable. This eight conductor shielded
flat cable has RJ45 modular plugs on each end. Terminate one end of the cable at the
Maximus terminal’s serial option card and the other end at the host computer’s serial port
through an ATS RS232 communication adapter. Be sure to follow all applicable electrical codes
when installing the cable.
