Agilent 35900E Dual Channel Interface User Manual 1 Introduction Features 8 Independent Analog-to-Digital Converters 9 Real-Time Control 9 Instrument Control Ports 10 Host Computer Communication 10 Front Panel 10 Important Safety Warnings 11 Safety and Regulatory Certifications 12 Cleaning 14 Recycling the Product 14 The Agilent 35900 is a dual-channel run buffered interface that connects analytical instruments to Agilent data systems.
1 Introduction Features The 35900 (Figure 1) features include the following: • Data buffering • Independent analog-to-digital (A/D) converters • Real-time control • Instrument control ports • Host communication • Front panel indicators that show run status, interface activity, etc.
Introduction 1 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.
1 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. Host Computer Communication The 35900 has an MIO slot for host communications. There are presently two MIO cards that can be used with the 35900.
1 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. COMM—This light indicates that the 35900 is communicating with the host computer.
1 Introduction Safety and Regulatory Certifications The 35900 Dual Channel Interface conforms to the following safety standards: • International Electrotechnical Commission (IEC): 61010–1 • EuroNorm (EN): 61010–1 The 35900 Dual Channel Interface conforms to the following regulations on Electromagnetic Compatibility (EMC) and Radio Frequency Interference (RFI): • CISPR 11/EN 55011: Group 1, Class A • IEC/EN 61326 • AUS/NZ This ISM device complies with Canadian ICES-001.

Agilent 35900E Dual Channel Interface User Manual 2 Setup To Unpack the Unit 16 Checking Parts and Accessories 16 Line Voltage 16 Configuration Switch 17 This section provides procedures for unpacking and configuring the 35900 Dual Channel Interface.
2 Setup To Unpack the Unit 1 If the 35900 is purchased as part of a system, check the carrier's papers to verify that you received all containers. 2 Inspect the shipping container for damage and watermarks. 3 Remove the cables and documentation from the shipping container and set them aside. 4 Unpack the 35900 and inspect it for damage. If you see damage, keep the carton and all packing materials for the carrier's inspection. Contact your nearest Agilent Technologies Sales and Service Office immediately.
Setup 2 Configuration Switch There is a set of six configuration switches on the rear panel that control 35900 operation. The default settings are shown in Figure 2. Table 1 describes the individual switch settings. 23 '0)" ! ).342 0/24 2%-/4% $)')4!, ) / !.

Agilent 35900E Dual Channel Interface User Manual 3 Computer Connection Handling the MIO Card 20 Connecting to a TCP/IP Network 20 Configuring a GPIB/RS-232 MIO Card 22 Connecting to a Host Computer Using GPIB or RS-232 Communications 26 The 35900 and the host computer are connected through a Modular I/O (MIO) card. This type of removable card allows you to configure the 35900 with the correct type of link to communicate with your host computer.
3 Computer Connection Handling the MIO Card CAU T ION The MIO card is static-sensitive and should be handled with static safe procedures to avoid damage. When handling the board, use the following precautions: • Use antistatic equipment during installation, such as a grounding mat and wrist strap. • Hold the board by its edges. • Do not touch the board’s electrical components, or edge connectors. Connecting to a TCP/IP Network The 35900 with a TCP/IP MIO card installed has an Ethernet IEEE 802.
3 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.
3 Computer Connection Configuring a GPIB/RS-232 MIO Card The GPIB/RS-232 MIO card allows the host computer to communicate with the 35900 through either an RS-232 or a GPIB connection. By setting the configuration switches on the card you can configure the type of connection desired. Review your data system’s installation instructions to determine compatibility. If necessary, the board switch settings can be inspected or changed by removing the board from the rear of the unit.

3 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.
Computer Connection 3 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. Switch 5 set to OFF indicates odd parity. Switches 6 through 8 combine to indicate baud rate. See Table 4 for switch settings and their corresponding baud rates.
3 Computer Connection Connecting to a Host Computer Using GPIB or RS-232 Communications The 35900 with a GPIB/RS-232 MIO card installed has two host connector types (Figure 7). Only one of these connectors can be used to connect to a host computer at a time. Use the GPIB connector (Table 5) when attaching to a host requiring GPIB communications. Use the RS-232 connection when the host uses this protocol. To configure the card, see “Connecting to a TCP/IP Network” on page 20.

4 Instrument Connection Analog Input (Signal) Connection The signal must be within the range of -18 millivolts to 1 volt. A simple voltage divider resistor network may be used to attenuate larger signals to this range. Each input has three pins to which the high (+) and low (–) sides of the signal and the shield are connected. Use an instrument-specific cable (Table 6) whenever possible. Use a general purpose cable in those cases where a custom cable is not available.

See also Table 8.
4 Instrument Connection Digital I/O Connection Each channel has a 25 pin female connector with 16 signal lines. Of the 16, eight are bidirectional input/output signals (for such functions as valve control) and the remaining eight lines are input-only signals (for such functions as reading bottle-number inputs). A "Y" adapter cable (Figure 10) is available to route the 16 digital I/O signals to two 9-pin connectors.
