9.2 Setting up the RS-232 Port for Remote Control The 3001 is fully programmable over a standard RS-232 link with a PC. The RS-232 cable length for the port should not exceed 15 meters (50 feet), although longer cable lengths are permitted if the load capacitance measured at a connection point (including signal terminator) does not exceed 2500 pF.
When using the IEEE-488 remote control interface, there are two restrictions: • A maximum of 15 devices can be connected in a single IEEE-488 bus system. • The total length of IEEE-488 cables used in one IEEE-488 bus system is 2 meters times the number of devices in the system, or 20 meters, whichever is less. See section 8 for instructions on configuring the 3001 for IEEE-488 (GPIB) operation, including selecting the interface and the bus address. A typical IEEE-488 (GPIB) connection is shown in Figure 32.
or via the IEEE-488 message LLO (Local Lockout), the 3001 front panel controls are totally locked out. The left end of the top line of the display changes to: rem. To return the 3001 to the local with lockout state, send the RS-232 LOCAL command or the IEEE-488 GTL (Go To Local) message. Table 4 summarizes the possible operating state transitions. For more information on IEEE-488 GPIB messages, see section 9.5.
9.6 Using Commands Communications between the controller and the 3001 consist of commands, queries, and interface messages. Although the commands are based on the 488.2 standard, they can be used on either the IEEE-488 or RS-232 interface, except for a few specific RS-232 only commands as described in the subsection Commands for RS-232 Only below. For more detailed information on IEEE command structures, see the IEEE 488.2 standard.
An important thing to note about interface messages is that, unlike devicedependent and common commands, interface messages are not sent literally (in a direct way). They are converted to parallel signal levels on the bus data and control lines. IEEE-488 standards define interface messages which are handled automatically in most cases. e) Compound Commands A compound command is two or more commands placed on a single command line separated from each other with semicolons.
For these commands, the detailed command descriptions in section 10 show a check mark X beside RS-232, but no check mark beside IEEE-488. Table 6 - Commands for RS-232 Only IEEE-488 Message RS-232 Equivalent GTL LOCAL command GTR REMOTE command LLO LOCKOUT command i) Commands for IEEE-488 These are all of the commands except for those used for RS-232 only, as described above.

Figure 33 - Status Register Overview Table 9 lists the status registers and gives the read/write commands and associated mask registers used to access them. Table 9 - Status Register Summary Status Register Read Command Write Command Serial Poll Status Byte (STB) *STB? — Service Request Enable Register (SRE) *SRE? *SRE Event Status Register (ESR) *ESR? — Event Status Enable Register (ESE) *ESE? *ESE Each status register and queue has a summary bit in the Serial Poll Status Byte.
The Calibrator sends the serial poll status byte (STB) when it responds to a serial poll. This byte is cleared (set to 0) when the power is turned on. The STB byte structure is shown in Figure 34. Refer to the *STB? command in section 10 for more information on reading this register. 7 6 5 4 3 2 1 0 0 RQS MSS ESB MAV EAV 0 0 0 RQS Requesting service. The RQS bit is set to 1 whenever bits ESB, MAV, EAV, or ISCB change from 0 to 1 and are enabled (1) in the SRE.
Many of the remote commands require parameters. Improper use of parameters causes command errors to occur. When a command error occurs, bit CME (5) in the Event Status Register (ESR) goes to 1 (if enabled in ESE register), and the error is logged in the error queue. 6) Event Status Enable (ESE) Register A mask register called the Event Status Enable register (ESE) allows the controller to enable or mask (disable) each bit in the ESR. When a bit in the ESE is 1, the corresponding bit in the ESR is enabled.
to binary represents bits 0 through 15. 9) Output Queue The output queue is loaded whenever a query is processed, and holds up to 250 characters. The controller reads it with a statement such as a BASIC INPUT statement, removing what it reads from the queue. If the queue is empty, the 3001 does not respond to the INPUT statement from the controller. The Message Available (MAV) bit in the Serial Poll Status Byte is 1 if there is something in the output queue, and 0 if the output queue is empty.

11. Maintenance 11.1 Cleaning the Calibrator Warning To avoid personal injury and/or damage to the Calibrator, use only the specified replacement parts and do not allow water into the case. Caution To avoid damaging the case, do not use solvents or abrasive cleaners. Clean the calibrator and pressure modules with a soft cloth dampened with water, or mild soap and water. 11.2 Replacing a Line Fuse Warning To avoid electrical shock hazard disconnect line power before opening the case or fuse compartment.
11.3 Changing the Line Voltage The calibrator arrives from the factory configured for the line voltage appropriate for the country of purchase, or as specified when it is ordered. To verify the line voltage setting, check the line voltage indicator on the power line fuse compartment cover. Confirm that the line voltage selection is set for 120 V for line voltages between 90 V and 132 V, or that the selector is set to 240 V for line voltages between 198 V and 264 V.
