  • Page 9: Independent Analog-To-Digital Converters

    Introduction Independent Analog-to-Digital Converters The analog-to-digital channels provide 24-bit analog-to-digital conversion of up to two independent analog signals. The analog inputs can either be totally asynchronous (have no relationship at all to each other) or synchronous (separate signals, but logically related to the same START reference). To allow asynchronous operation, each channel has separate Start/Stop switches, status indicators, and controllable digital I/O.

  • Page 10: Instrument Control Ports

    Introduction Instrument Control Ports There are two RS-232 ports (one for each channel) that may be used to interface with RS-232 compatible lab instruments such as certain autosamplers, balances, GCs, etc. Line protocols and operating modes for RS-232 communication are configured via commands from the host computer.

  • Page 11: Hardware Monitoring Indicators

    Introduction NOT READY— This light indicates the channel cannot start another run until other events are completed. Hardware monitoring indicators There are four indicator LEDs on the bottom of the front panel that display the status of the 35900. ACTIVE— Indicates that there is data present in the interface that will be lost if the 35900's power is turned off.

    Computer Connection Handling the MIO Card The MIO card is static-sensitive and should be handled with static safe procedures to CAU T ION avoid damage. When handling the board, use the following precautions: • Use antistatic equipment during installation, such as a grounding mat and wrist strap. •...
  • Page 21 Computer Connection To communicate with the 35900, you must assign it an IP address compatible with the site LAN. The TCP/IP MIO card must receive its address from a BootP server/service (or DHCP server if supported by the Agilent data system). The TCP/IP MIO card MAC address (see Figure 4) is printed on a label on the outside of the TCP/IP MIO card as seen in Figure 3.

  • Page 24: Configuration For Rs-232 Operation

    Computer Connection Configuration for RS-232 operation The GPIB/RS-232 MIO card contains a single 8 position configuration switch (Figure 6). When the position 1 switch is set to ON, the MIO card uses the RS-232 communication mode. In this mode, the ON switch positions for switches 2 through 8 are defined in Table 3.

  • Page 25: Installing The Communication Card

    Computer Connection Because switch 1 is set to ON, the board is in RS-232 mode. Switch 2 set to ON indicates that handshaking is enabled. With handshake enabled, switch 3 set to OFF indicates software handshaking. Switch 4 set to ON enables parity checking.
