COMMUNICATION TESTS
GENERAL
1. Verify that the external communication devices are located in the proper environment as
described below.
CRT/Data Terminal
When a CRT or data terminal is used with the system it should be located in a clean, office-
type environment. It should not be installed over a hazardous location. CRTs/data terminals
supplied by GASBOY have an operative temperature range of 32
o F to 104 o F. Locating the
terminal in a dirty environment may cause premature failures. The terminal should be
located as close as possible to the Site Controller.
Modem
When a modem is used with the system, the modem should be located in an office-type
environment. If this is not possible, it should be housed in a protective enclosure with
ventilation. It should not be installed over a hazardous location. External modems supplied
by GASBOY have an operative temperature range of 32
o F to 104 o F.
Step 2 checks vary for the Site Controller II and the Islander II. Follow the appropriate steps
for your unit.
2. Site Controller II
Verify that the cables for the four communication ports meet the installation requirements
listed below.
Port 0 Data Terminal
Normally uses an 8-foot RS-232 EIA cable (P/N C04549) and connects to the data terminal.
If a data terminal is not used on the logger port, a logger eliminator (P/N C05593) must be
used.
Port 2 Modem
Normally is connected to a modem and uses an 8-foot 1:1 EIA cable (P/N C04549). If this
port is connected directly to a PC or a terminal, use a cross-cable (P/N C05039). (See
Appendix C of Site Manager's Manual for cable configuration).
Ports 1 and 3
These are general purpose RS-232 ports that will work with various external devices such as
a direct pump interface, Hayes-compatible modem (for bank interface), or logger. These
ports are configured using jumper blocks K1 and K2.
Power
The AC power for the peripheral equipment, except for the Profit Point and its accessories,
should be supplied by the power conditioner (or can be on a separate dedicated circuit
breaker). The Profit Point and its accessories must be powered from an AC Surge Protector
Outlet Strip (C01218)
NOTE: All conduit, system and pump/dispenser wiring must be installed according to the
specifications detailed in the Site Controller II Installation Manual.
