Tank Monitoring System (Optional)
1 Verify that the tank monitoring system is correctly connected to the Site Controller according
to the Site Controller III Installation Manual.
2 Refer to the tank monitoring system manufacturer’s installation instructions for specific
connection information.
Current Loop Interface (Optional)
Note: Gilbarco pump and CRIND PC interfaces are recommended over the current loop
interface.
1 Verify that the current loop interface unit is located in an office-type environment and is
correctly installed according to its installation sheet.
2 Make sure the special RS-485 communication modular cable is directly connected between
the current loop interface unit (slot labeled RS422) and the RS-485 junction box using the
appropriate RS-485 modular jacks.
Note: The modular cable from the current loop interface unit to the RS-485 junction box is
GASBOY P/N C04500 (cross) modular cable. Other devices (Site Controller, Console
to junction box, etc.) can use GASBOY P/N C05670 (1:1 cable).
3 Verify that the two wire current loop communications is correctly wired to the distribution box
according to the Current Loop Interface Unit Installation Manual or Pump Interface Manual.
CRIND Connections (with Current Loop Interface only)
For CRIND devices, a universal distribution box must be used. Verify that the modular cable
connects from the second RS-485/RS-422 port on the back of the current loop interface to an
adaptor, and from there to a 9-pin connector on the distribution box. Refer to the Current Loop
Interface Unit Installation Manual or Pump Interface Manual.
Gilbarco Pump Interface Using PC COM Port
