COMMUNICATIONS OPTIONS AND OPERATING MODES
Hardware
Requirements
A CRT or data terminal with an ASCII character set, or a computer with the proper
interface, is required to communicate with the Series 1000. The CRT, data
terminal or computer is connected to the system through one of two
asynchronous communication ports located in the system pedestal.
Communication may be through direct wire, or by dial-up phone lines using the
optional internal 300/1200 baud modem. An optional auxiliary port PCB (2 ports)
is also available for connection to a receipt printer and/or tank monitoring system.
See Section 6, Communications, for specific communication requirements and
distance limitations.
•
Port 1 is normally used for direct connection of a data terminal located at the
site. This port allows access to the system’s Direct Printout Mode and
Command Mode. In Direct Printout Mode, transactions print (or display) on
the data terminal as they occur. When connected to this port, the CRT or
data terminal remains in Direct Printout Mode until the commands are issued
to enter Command Mode. To ensure the security of the information in the
system, Command Mode can only be accessed using the proper password.
Once signed on, the operator can update pump and tank information;
validate/invalidate cards, vehicle records, and keys; and retrieve recorded
transactions in a variety of formats.
•
Port 2 is commonly used to connect to a remote data terminal or computer.
Port 2 allows access only to the Command Mode.
•
The auxiliary ports are used to connect a receipt printer and/or tank
monitoring system. If you ordered your system with a receipt printer and/or
tank monitoring system, this port is already present. No additional wiring is
required for the receipt printer. See Section 6 of this manual for installation
wiring for a tank monitoring system.
