5. Select the data word (16 bit data) from the list and

press Enter. Continue to set the other data words in

the same manner. Many data items consist of two

words (32 bit data). It is important that you configure

both words in order to transmit useful information to the

DTU3005’s registers.

6. Use these options as follows:

a. Select Set Defaults to copy the default custom

device registers to the list. See Section 4.7.2 for

instructions on setting custom device registers by

device type.

b. Select Clear All to delete all register names from

the list.

c. Select Set as Defaults to save the current cus-

tom register list as the default custom register list.

This will not change the custom registers of other

devices of the same type. See Section 4.7.1 for

instructions on setting custom device registers for

a single device.

4. Select Save to save your custom register list and then

Ok to exit this dialog box. Select Cancel to exit this

dialog box without making changes.

To conserve registers when using VDEW devices, you

should set all unused registers to “Not Used” and place

them at the end of the list. The DTU3005 will then only allo-

cate registers for those containing device data. (This does

not apply to SEAbus devices, for which the DTU3005 allo-

cates 16 registers regardless if they are used or not.)

4.7.2 Configuring Default Custom Device

Registers by Device

If you are configuring custom device registers for more than

one device of a certain type, you may configure the default

custom registers from the Edit Menu Device Defaults

command. After configuring the default device registers, you

may use them for any or all devices, or further customize

individual registers for any of your devices. SEAbus devices

can have 16 custom registers. VDEW devices may have

between 1 and 64 custom registers.

To configure default custom registers for a particular device

type:

1. Select Device Defaults from the Edit menu. A list of

devices appears. If you have configured port 2 for SEA-

bus devices, only SEAbus devices will appear on the

menu. Likewise, if you have configured port 2 for VDEW

devices, only VDEW devices will appear on the menu.

2. Select the device you wish to configure. The default

custom register configuration menu appears. The first

time you select this command, the first 16 registers (64

for VDEW devices) from the device’s standard data reg-

ister list appear on the default real-time data list. Not all

of the entries are visible on the menu. Use the scroll bar

or the Page Up and Page Down keys to view all the

entries.
