of the DC power source. Connect the “-” terminal to the negative output of the DC power source.
Note that the Tempus LX has a “floating” internal power supply, therefore either the positive or nega-
tive output of the DC power source can be referenced to earth ground. This unit will not operate if
the +/- connections are reversed; however it will not be damaged by a reverse connection.
SHOCK/ENERGY HAZARD
Install in Restricted Access Location.
Use 10-14 AWG copper wire only.
Terminal block screw torque: 9 in-lbs (1 nM).
Branch circuit must have circuit breaker, 15A or less.
Install terminal block cover after wiring.
Connecting and Configuring Ethernet
Connect one end of the CAT-5 patch cable supplied with your Tempus LX to the rear panel mounted
RJ-45 connector labeled 10/100BASE-T. Connect the other end of the patch cable to your network
through a ‘straight’ port on your hub. Do not connect it to a ‘crossover’ port on your hub.
By factory default, the Tempus LX will attempt to configure the ethernet interface automatically via
the Dynamic Host Configuration Protocol (DHCP). The Tempus LX will attempt to set the netmask,
its IP address, the IP address of the default gateway, the domain name and the IP addresses of any
nameservers, if the DHCP server is configured to provide them. You may optionally configure the
Tempus LX to also set its hostname via DHCP, if your DHCP server is configured to provide it. You
can do this by running a simple shell script called
netconfig
after your unit is up on the network.
If your network does use DHCP for host configuration, and you are in a hurry to get your Tempus LX
up and running, you may procede to
Verifying Network Configuration
to make sure that the network
parameters were set up correctly. Otherwise, it is recommended that you read the following sections
on use of the RS-232 serial I/O port now, since they will help you in debugging any problems that
you may encounter with the automatic configuration via DHCP.
If your network
does not
use DHCP, you will need to configure your ethernet interface using either
the front-panel keypad or the RS-232 serial I/O port. The following sections contain brief descrip-
tions on how to do that.
Configuring Ethernet with the Front-Panel Keypad
Configuring your ethernet interface with the front-panel keypad is quite simple. After the unit has
powered on, press the ENTER key once or twice until you see a display called Main Menu. Now
press the RIGHT arrow key until the “Network” selection is highlighted. Press ENTER again. You
will see the IP address, gateway and netmask settings displayed here. Press the EDIT key to modify
these settings. The sequence of edit displays will guide you through the setup process. Press the
HELP key at any time to view context-sensitive help information. When you are finished the unit
will reset. Skip to the section called
Check Network Operation
later in this chapter to continue with
the basic installation procedures.
