    48 GPI (General Purpose Interface) inputs and outputs to 100/10baseT Ethernet or a serial interface. Up to 8 gBOXes may be slaved off a master gBOX to convert up to a total of 432 GPI inputs and outputs. The gBOX communicates over standard TCP/IP which allows it be used with any host computer running any operating system that uses TCP/IP protocol.

    • Server • Client The DIP switches are read only at power on so the gBOX must be power cycled for the changes to take effect. Serial When the gBOX has a serial Interface installed, it has just one distinct mode of operation. This is GPI to serial conversion.

  • Page 8: Ethernet Interface

    Mode Selection When DIP switch 5 on the left side is in the Off position, the gBOX behaves as a server. That is, the gBOX waits for a device such as a host computer or client gBOX to establish a connection to it.

  • Page 9: Server Mode

    Server Mode In the Server Mode of operation, DIP Switches 1, 2, 3 and 4 on the left side set the IP address of the gBOX. The units IP address is set according to the table below. 192.168.254.102 192.168.254.104 192.168.254.106 192.168.254.108...

    Client Mode In the Client Mode of operation, DIP Switches 1, 2, 3 and 4 on the left side set the IP address of the gBOX. The units IP address is set according to the table below. 192.168.254.103 192.168.254.105 192.168.254.107 192.168.254.109...

  • Page 11: Serial Interface

    The gBOX can be daisy chained to allow one Ethernet or Serial connection to accommodate up to 432 GPI Inputs and Outputs. When the rear panel slot is vacant, the gBOX assumes it is an expander unit and uses the rear panel DIP switches 1, 2 and 3 on the left side to set the expander ID.

    Serial When the 920466 Standard RS-232 Interface Card or the 920465 Standard RS-422 Interface Card is installed the unit is a simple GPI to serial converter. The pinout of the serial interface is detailed in the table below. Interface RS-232C RS-422A RS-422A “Mach”...
  • Page 15 Serial port communications occurs with the following parameters: • Bit rate: 38400 bits/sec • Start bits: • Data bits: • Stop bits: The parity of the serial port can be set on the leftmost set of DIP switches on the rear panel. The parity is set using the following table.

    GPI In ports to each other so it can be shown on the GPI Out port on the remote gBOX. After that, changes to a GPI In port will cause a gBOX to send a GPI message to the remote gBOX.

  • Page 17: Gpi Port Circuitry Details

    The gBOX GPI input and output circuits are detailed in the following section. The inputs of the gBOX GPI ports are CMOS inputs. The input circuitry has a 4700 ohm pullup resistor to +5 volts as referenced to pin 1 of the GPI Input Port.
  • Page 18 The outputs of the gBOX GPI ports are also CMOS. The output signal is referenced to pin 1 of the GPI Output Port. The GPI Outputs are rated to +/- 6mA. If this is not sufficient for your application, consider using the eBOX I/O.

  • Page 19: Using With Ebox I/O

    The eBOX I/O comes with a pair of cables that allow you to connect it to a single eBOX I/O to a gBOX. Up to six eBOX I/Os can be used with a single gBOX. To connect two or three eBOX...
