Connecting the Serial Cables
Connect the serial (RS-232C) cables for the FC-1000 data collector,
computer, modem, etc., to the GB-500's serial ports. The receiver
has three serial ports: A, B and C. Each serial port corresponds to a
specific external device (Figure 2-5):
• Port A – FC-1000 controller
• Port B – Computer
• Port C – Modem
Above each port is a colored mark: yellow for port A, green for port
B, and white for port C. The red mark indicates the power port.
