Page 9: Safety Instructions
All existing regulations must be complied with. Attention must be drawn to residual dangers associated with measuring equipment. After setting up and password protected activities, ensure that any controllers that may be connected are in a safe status, until the switching behaviour of the measuring amplifier has been tested. DMP40, DMP40S2...
Page 10 Warns of a potentially dangerous situation in which failure to comply with safety requirements can lead to death or serious physical injury. CAUTION Symbol: Meaning: Possibly dangerous situation Warns of a possibly dangerous situation in which failure to comply with safety requirements could cause damage to property or result in some kind of minor physical injury. DMP40, DMP40S2...
Page 11 Any modification precludes liability on our part for any resulting damage. In particular, all repairs and soldering work on motherboards (replacement of components other than EPROMs) are prohibited. When replacing complete modules only original HBM parts may be used. Qualified personnel are persons who are entrusted with the installation, assembly, commissioning and operation of the product and who possess the appropriate professional, trade or craft qualifications.
Page 12 The amplifier complies with the safety requirements of DIN EN 61010, Part 1 (VDE 0411, Part 1); Protection Class I. To ensure sufficient electromagnetic immunity, it is essential to use Greenline shielding only (see HBM brochure "Greenline shielding design"; internet download http://www.hbm.com/Greenline).

Page 14 This section gives a clear explanation of how the DMP amplifier works. You can connect as many as eight sequentially selectable channels to the DMP40. Connected transducers (operat ing on the SG principle) are excited with a 225 Hz carrier frequency. Since all the transducers are connected to the excitation voltage at the same time and are therefore constantly "warmed up", as soon as you switch to the next...

Protect the amplifier from humidity or atmospheric influences such as rain, snow and so on. • Please ensure that the ventilation openings in the side and the power pack fan vents in the back of the amplifier are not covered up. DMP40, DMP40S2...
Page 19: Maintenance And Cleaning
Clean the housing with a soft, damp (not wet) cloth. Never use solvents, since these can damage the display field as well as the makings and labeling on the front panel. • Make sure that no liquids find their way into the amplifier or its connection ports in the course of cleaning.

Page 149 Interfaces compared The DMP40 incorporates three different interfaces: • an RS 232 C, • an RS 485 and • an IEEE 488 78. At any one time the device can be operated through one interface only; each has certain advantages but also disadvantages.
Page 150 Interfaces compared IEEE 488 78 interface (Chapter D) Parallel data transfer • Transmission rate relativly "high". • Several devices can operate in a link up. Data transfer is faster than when using a serial interface. The maximum transmission rate for measured values is no higher than when communication is serial (at least 9600 baud).

Page 153: Rs 232C And Rs 42/485 Interfaces
RS 232C/RS 485/422 serial interfaces RS 232C and RS 42/485 interfaces Both interfaces are designated serial interfaces since data is transferred in sequence, bit by bit. They differ in the voltage level used and in construction; the RS 232C interface is suitable for point to point connections, the RS 422/485 for bus operation.
Page 154 RS 232C/RS 485/422 serial interfaces Data transfer is controlled by means of the software handshake X ON (DC1) and X OFF (DC3). If the computer is ready to receive data, it sends the control character X ON (DC1) down the data line. If it cannot accept data, e.g.
Page 155: Rs 422/485 Bus
The bus shown here is an extension of the RS 422 interface permitting − unlike the latter − more than one trans mitter. Each DMP40 has a receiver and a transmitter; the transmitter can be switched on or off with the SELECT commands.

Page 160: Addressing
IEEE 488 78 parallel interface→ Addressing Addressing Each of the devices functioning together in a link up must have its own address so that they can be correctly distin guished by the controller. These addresses are generally set with a switch and numbered consecutively from 0 to 30. Each device can be addressed at its individual address.
Page 161: Service Request (Srq)
IEEE 488 78 parallel interface Ý Service Request Service Request (SRQ) Each of the devices functioning together in a link up must have its own address so that they can be correctly distin guished by the controller. In a link up of several measuring amplifiers a measurement run can occupy a considerable time span. The control ler waits for this task to finish.
Page 162: Serial Poll (Spoll)
IEEE 488 78 parallel interface Ý Service Request Serial poll (SPOLL) If a Service Request occurs during a measurement, by initiating a serial poll the computer can identify the device which has caused the interrupt. The computer must address all devices and query the status value. By this means the computer can also determine the cause of the interrupt.
Page 163: Parallel Poll (Ppoll)
In a parallel poll the controller receives no indication as to the reason for the SRQ. If the controller transmits the identification command (EOI + ATN = IDY = True), the devices must set the data line assigned to them. HBM de vices are activated with the interface command PPM.

IEEE 488 78 parallel interface Ý Interface commands Interface commands These commands are not among the device commands described later. They apply to the IEEE interface only. The table below lists the most important of these commands. The commands are to be output via the interface as ASCII code. If this does not happen automatically in the com puter an appropriate translation routine is required.
