1.1 Period and Scope of Warranty

Delivered products are under warranty for a period of one year after delivery.

During the period of warranty, the vendor will have his own to responsibility replace or repair malfunctioning

parts if the product malfunction is the responsibility of the vendor.

However, this warranty does not apply under the following circumstances:

(1) If the user handles or uses the product in an inappropriate way

(2) If the malfunction is caused by something other than the delivered product

(3) If the delivered product has been modified or repaired by anyone other than the vendor

(4) Due to natural disaster, accident, or other reason not the responsibility of the vendor

In this context, the term “warranty” means solely a warranty of the individual delivered product, and does not

include any compensation for the damage caused by malfunction of the delivered product.

1.2 Scope of Service

The service costs such as the costs of sending technical personnel are not included in the price of the delivered

product. Customers will be charged for the following costs:

(1) Assistance with installation adjustments and test running

(2) Maintenance inspections, adjustments, and repairs

(3) Technical assistance and technical training

2. Features

z VME double-high, 12-bit resolution A/D conversion board with a single slot and 64 channels that are compatible

with A16, D16, and D8 (EO)

z For the input range, all channels can be collectively selected among the following four channels by setting a jumper:

(1) ±10 [V]

(2) 0 to 10[V]

(3) 0 to 5[V]

(4) 1 to 5[V]

The product with the current mode for the following ranges is also available:

(5) 4 to 20[mA] Current mode (the 1 to 5V range is used)

(6) 0 to 20[mA] Current mode (the 0 to 5V range is used)

z The number of the input channels is 64 in the single-end type, and 32 in the differential type.

The single-end and differential types are switched by short pins for all channels collectively.

z Equipped with a photo-coupler that assures complete insulation between the analog and digital circuits, but not

between input channels

z A/D is sequentially converted by switching each channel with the multiplexer.

z The conversion time is 1920µs for 64-channel batch conversion and 960µs for 32-channel batch conversion.

z Using the software, a trigger input to start A/D conversion can be selected among the following four types:

(1) 32ch batch conversion by a trigger from the software

(2) 64ch batch conversion by a trigger from the software

(3) 32ch batch conversion by an external trigger signal from the P2 bus

(Simultaneous sampling of multiple boards is possible)

(4) 64ch batch conversion by an external trigger signal from the P2 bus

(Simultaneous sampling of multiple boards is possible)

The external trigger signal not only can turn ON/OFF with a jumper but can select polarity.

z A/D conversion automatically starts after inputting the trigger, and the converted data are sequentially written to

the data register in the ascending order of the channel numbers. The host CPU detects the end of conversion

through an interrupt to allow data to be read from each data register. This can lessen the burden of the host CPU.

z Operates on single 5V power supplied from the VME bus

z RoHS compliant

5.2 Base Address Setting (DSW1,DSW2)

The Advme2607 takes up a 256-byte (100H) consecutive area in the VME bus A16 short address space 0000H to

FFFFH.

The starting address of the required area is referred to as a base address (BASE).

The base address is assigned with the DIP rotary switches, DSW 1 and 2.

DSW1 is used to assign addresses corresponding to A15 to A12(0-F) address buses, and DSW2 to assign ad-

dresses corresponding to A11 to A8 (0-F) base address buses.

The following equation shows a correspondence between the base address (BASE) and DSW1 (DSW2).

Base address [BASE] = DSW1 set value × 1000H + DSW2 set value × 100H

When DSW1 is set to D and DSW2 is set to 6:

BASE = D × 1000H + 6 × 100H

= D600H

5.3 Analog Input Form Setting (JP1)

The Advme2607 allows the setting of analog input formats all at once to single-ended or differential input.

The number of input channels is 64 for single-ended inputs and 32 for differential inputs.

5.4 Analog Input Range Setting (JP2)

The Advme2607 is capable of setting the input voltage range for each channel.

The following shows the jumper settings of each range.

0 ～ 5 [V]

0 ～ 20 [mA]

5.5 External Trigger Setting (JP3)

Offering the mode that executes A/D conversion by the external trigger, Advme2607 can turn ON/OFF this exter-

nal trigger input. It can also set execution with the rising edge or with the falling edge of the trigger signal, using

the “trigger setting register”. The minimum pulse width of the input signal is 400 [ns].

5.6 Analog Input Adjustment (VR1, 2 and 3)

Every time a range is changed, Advme2607 requires adjustment in the range.

Prepare the equipment shown in (1) to (4) below. Adjustment is divided into coarse and fine adjustment for execution.

Advme2607 can adjust the gain and offset common in each channel.

The following shows the necessary equipment:

(1) Extension board

(2) Standard voltage generator

(3) Voltmeter (digital multi-meter)

(4) Test program (The program displaying the A/D converted values of all channels)

5.6.1 Coarse Adjustment

Coarse adjustment is executed by the following procedure regardless of the range to be set:

(a) Insert Advme2607 into the VME rack using the extension, and power on the VME rack.

(b) Connect the voltmeter between A-GND and TP6, and adjust VR3 so the voltmeter reads 2.500[V].

(d) Set the input range to ±10[V], connect the voltmeter between A-GND and TP4 keeping all input channels

short-circuited with the ground, and adjust VR1 so the voltmeter reads nearly 0.00[V].

5.6.2 Fine Adjustment

The method for fine adjustment varies depending on the range set. Adjust each range by the procedure below:

z Range of ±10[V]

(a) Connect the output of the standard voltage generator to Channel 0 to activate the test program.

(b) Set the output voltage to 0[V]. Adjust VR1 such that the data becomes 800H.

(d) Set the output voltage to -10[V]. Check that the data is within the range of 030H ±4.

z Range of 0 to 10[V]

(a) Set to the ±10[V] range for fine adjustment similar to the ±10[V] range.

(b) Set JP2 to the 0 to 10[V] range.

(d) Set the output voltage to 10.00[V]. Check that the data is within the range of FD0H ±4.

(e) Set the output voltage to 0.00[V]. Check that the data is within the range of 030H ±4.

(f) If the data in (d) and (e) do not fall within the specified range, another adjustment is necessary in the

way shown in the next page depending on how far the data are from the range.

JP3

Short External trigger is used.

Open External trigger is not used.

VR1 Bipolar offset

VR2 Gain

VR3 Unipolar offset

Where the data in (d) is Ud and the data in (e) is Ld,

Supposing that sp = Ud - Ld,

it is confirmed that the gain is too large in sp > 4000 (FA0H),

whereas the gain is too small in sp < 4000 (FA0H).

Gain adjustment is executed in VR2 in both cases.

First, connect the voltmeter between A-GND and TP5 to read the voltage from the voltmeter. Let the read

value be Vr.

There is the following proportional relation between sp and Vr:

sp = (1562.5+ ε ) · Vr where ε is an error of the circuit constant.

Assigning (1562.5+ ε ) to k makes:

sp = k · Vr, which allows the value of k to be calculated from the measured sp and Vr.

k = sp / Vr

SP must be adjusted by adjusting Vr. As SP is 4000 in Advme2607, the following formula is made:

4000 = k(Vr + ∆ ν ) = k · Vref + k · ∆ ν

∆ ν = (4000 - k · Vref) / k

= (4000 - sp) / k

How much Vr should be changed (∆ ν) can therefore be calculated.

The following shows the relation between SP and the variation of Vref in case of ε = 0 for reference:

For instance, where the data that applies 10.00[V] is FD5H(4053) and the data applying 0.00[V] is 02CH(44),

the equation goes:

sp = 4053 - 44 = 4009

representing SP being slightly large. If the voltage between A-GND and TP5 is 2.562[V] here, VR2 should be

adjusted to around 2.556[V], which is smaller by approximately 6[mV].

(g) Adjust VR2 as above to further repeat the procedure in (c) onwards.

SP Δν

3980 +12.80[mV]

3990 + 6.40[mV]

4000 ± 0.00[mV]

4010 - 6.40[mV]

4020 -12.80[mV]

z Range of 0 to 5[V]

(a) Set JP2 to the ±10[V] range for fine adjustment similar to the ±10[V] range.

(b) Set JP2 to the 0 to 5[V] range.

(d) Set the output voltage to 5.00[V]. Check that the data is within the range of FD0H ±4.

(e) Set the output voltage to 0.00[V]. Check that the data is within the range of 030H ±4.

(f) If the data does not fall into the specified range, an analysis and adjustment similar to (f) and (g) in the

0 to 10[V] range are necessary.

z Range of 1 to 5[V]

(a) Set JP2 to the ±10[V] range for fine adjustment similar to the ±10[V] range.

(b) Set JP2 to the 1 to 5[V] range.

(d) Set the output voltage to 5.00[V]. Check that the data is within the range of FD0H ±4.

(e) Set the output voltage to 1.00[V]. Check that the data is within the range of 030H ±4.

(f) If the data does not fall into the specified range, an analysis and adjustment similar to (f) and (g) in the

0 to 10[V] range are necessary.

z Range of 0 to 20[mA]

This range basically requires the same adjustment method as the 0 to 5[V] range. An electric current is

converted to voltage by the 250Ω resistance of the input circuit. An error included also in the 250Ω resis-

tance is channel-specific, and therefore unable to be adjusted.

Therefore, causing JP4 to JP67 short-circuit after adjustment in the same way as the 0 to 5[V] range means

the completion of adjustment in the 0 to 20[mA] range.

Adjustment of this range does not require the removal of all short pins from JP4 to JP67, but only needs the

removal of the short pins corresponding to the arbitrary channels to be connected to the general voltage

generator.

z 4 to 20[mA]

This range basically requires the same adjustment method as the 1 to 5[V] range.

Other explanation is the same as that for the 0 to 20[mA] range.

5.7 In Current Mode

Cause short-circuit in JP4 to 67. JP4 to 67 correspond as follows:

JP4 → ch0

JP5 → ch1

JP67 → ch63

zTrigger choice

The trigger selected here automatically starts A/D conversion, and the A/D converted data is sequentially

written to the data register in the ascending order of the channel numbers.

zExternal trigger

A/D conversion by the external trigger from the P2 bus starts by writing “0” to D1 so the data of the specified

number of channels is written to the data register.

If D0 is “0”, 32-channel batch conversion is designated, and if it is “1”, 64-channel batch conversion is

designated. The signal of the Line A No. 23 pin of P2 of Advme2607 can be used as a trigger. This enables

simultaneous sampling with multiple boards. This external trigger can be turned ON/OFF in JP1. The polarity

of a trigger signal can be changed by setting the trigger setting register D2.

zTrigger by the software

To start the A/D conversion with a software trigger, set “1” to the D1. The number of designating channels is

determined by D0. If it is “0”, 32-channel batch conversion is designated, and if it is “1”, 64-channel batch

conversion is designated.
