The front panel is equipped with an analog output external connector (D-Sub socket). Using this connector, the

Advme2706 outputs analog signals. The connector pin configuration is as shown in the table below.

Note) AO1+ - AO16+ are the analog output signals for channels 1-16 respectively.

AO1G - AO16G are the grounds for channels 1-16 respectively.

AO1G - AO16G are connected internally in the Advme2706.

The front panel is equipped with an access LED (green). The access LED lights up when the Advme2706 is being

accessed. The LED lights up for approximately 100ms after the access is made to the Advme2706. So, if access is

made infrequently, the LED may get dimmed or blink.

6.1 Base Address Setting

The Advme2706 takes up a 64-byte (40H) consecutive area in the VME bus A16 address spaces C000h to FFFFh.

The beginning address of the region occupied in the VME bus A16 address space by the Advme2706 is called the

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

Among the addresses, A15 and A14 are fixed to 1, A13-A10 correspond to DSW1 and A9-A6 correspond to

DSW2 respectively. These switches are factory default to “0”.

7.2 Board ID Register

The board ID register reads board ID (48h) of the Advme2706. This ID is the same as that for the Advme2703.

This register is read only.The register can perform both word reading and byte reading.

7.3 Sub ID Register

The sub ID register reads sub ID (49h). The sub ID is used to differentiate the Advme2703 and the Advme2706.

This register is read only.The register can perform both word reading and byte reading.

7.4 Status Register

This register is used to indicate an internal state of the Advme2706.

BUSY ........... Indicates a state of data transfer to the D-A converter LSI.

0 : No data transfer or the transfer is completed (default)

1 : Data transfer is in process

EN ............... Monitors the EN bit of the enable register.

0 : 0V output from all channels (default)

1 : Enables output from all channels

MODE .......... Monitors the MODE bit of the mode register.

0 : Updates output per channel

1 : Updates batch output for all channels (default)

The BUSY bit is used to allow compatibility with the Advme2703. The Advme2706 allows writing to the indirect

data register, direct data register of each channel and update register irrespective of the BUSY bit state. In the

BUSY state, the Advme2706 makes the host CPU wait by delaying the return timing of the VME bus DTACK*

signal, until the previous data transfer to the D-A converter LSI is completed. (Even when writing to the data

This register is read only.The register can perform both word reading and byte reading. The initial value at reset is “0”.

When writing data, this register turns into a mode register.

00000MODEENBUSY

7.5 Mode Register

This register is used to set whether an analog input is performed for each channel or for all channels at once.

When the MODE bit of this register is 0, the analog input is performed for each channel. In this case, the analog

output is updated by writing data to the indirect data register or the direct data register of each channel.

When the MODE bit is 1, the analog input is performed for all channels at once. In this case, write any value to the

update register after writing data to the indirect data register or the direct data register of each channel. The analog

outputs of all channels are updated at the moment when data is written to the update register.

MODE .......... 0 : Updates output per channel (default)

1 : Updates batch output for all channels

This register is write only.The register can perform both word writing and byte writing. The initial value at reset is

“0”.The MODE bit state can be obtained by reading the status register.

When reading data, this register turns into a status register.

7.6 Enable Register

This register is used to enable analog outputs.

When the EN bit of this register is 0, the analog output of all channels is forcibly set to 0V. Also, writing to the

indirect data register, direct data register of each channel and update register is inhibited.

(Data written in this state is ignored.)

When the EN bit is 1, writing to the indirect data register, direct data register of each channel and update register

as well as analog output are enabled.

EN ............... 0 : 0V output from all channels (default)

1 : Enables output from all channels

This register is write only.The register can perform both word writing and byte writing.The initial value at reset is

“0”.EN bit state can be obtained by reading the status register.

7.7 Update Register

This register is used to adjust the output timing when updating all channel batch outputs (when the MODE bit of

the mode register is 1). The outputs of all channels are updated by writing any value to this register.

If the outputs are to be updated for each channel (when the MODE bit of the mode register is 0), there is no need

to access this register. (Writing will be ignored if performed.) In this case, the outputs are updated every time the

data is written to the indirect data register or the direct data register of each channel.

This register is write only.The register can perform both word writing and byte writing.

7.8 Channel Register

As with the Advme2703, each channel data can be updated using this register and the indirect data register. This

The setting range of the channel address is 0-15 (Fh). The relationship between the channel address and the

channel number is as follows.

Channel address = Channel number - 1

This register is write only.The register can perform both word writing and byte writing. Initial value of the channel

address is 0.

7.9 Indirect Data Register

As with the Advme2703, each channel data can be updated using this register and the channel register.After writing

the channel address to the channel register, set a D-A conversion value of the subject channel to this register.

The setting to this register is expressed with two’s complement as shown in the table below. Note that each voltage

value in the table is the calculated value and actual output values include errors.

The table lists values within the output range of ±10V (without a resistor for output range expansion).

They are approximately0.305176mV (=10V/2^15) per LSB.

The maximum value on the positive side is 1LSB smaller than the maximum absolute value on the negative side.

This register is write only.The register can perform both word and byte accessing.

When accessing to this register in byte unit, make sure to access in order of upper byte (even number address) and

lower byte (odd number address). When updating the output for each channel (when the MODE bit of the mode

7.10 Channel n Direct Data Register

The Advme2706 is equipped with a channel register and an indirect data register to allow compatibility with the

Advme2703. However, it is possible to set the D-A conversion values directly to each channel, without using the

channel register, by accessing this register. (The channel information is included in the VME address information.)

As with the indirect data register, the setting to this register is expressed with two’s complement. For relationship

between the input codes and the output voltage, refer to the section on the indirect data register.

This register is write only.The register can perform both word and byte accessing.

When accessing to this register in byte unit, make sure to access in order of upper byte (even number address) and
