MENUS
Axis Select
Select Axis Select from the Communications menu to select a single ULTRA Plus or IQ from a group of
ULTRA Plus or IQ units daisy-chained together on a multi-drop RS-422 serial link. To establish com-
munication, enter the address of the desired ULTRA Plus or IQ in the Axis Address box.
To communicate in multi-drop RS-422 mode, each ULTRA Plus or IQ must have had an address set
previously on dip switch SW1 on the ULTRA Plus or IQ board. Addresses are in the range 1 through 63.
If the address is left at 0 (default), the ULTRA Plus or IQ will not wait to be selected before transmitting
and can cause garbled communication if on a multi-drop link. Set the address as a binary number with
position 1 the least significant bit and position 6 the most significant bit of the address. If the address is
changed, the change will not take effect until power is cycled or a Hardware Reset is performed.
Address 0 is a global selection address-no response is allowed. If address 0 is sent in the Axis Address
box, all ULTRA Plus or IQ units in the system will execute any commands sent until a different address
is selected. Since no response is allowed from the ULTRA Plus or IQ, commands will not be echoed
back to the host, so Local Echo should be selected from PC Set Up when using Terminal mode in order
to view the commands in the Terminal window.
After your initial selection, IQ Master will remember the last address that you selected (unless it was
address 0) and display it the next time the Axis Select dialog box is displayed. The last address is valid
only for the current session of IQ Master.
Terminal
The Terminal mode allows direct communication to an ULTRA Plus or IQ or any serial device, includ-
ing BRU-200 or BRU-500 amplifiers or PRO-Series positioners. All PC communication parameters can
be set using PC Set Up from the Communications menu and can be changed even when the Terminal
mode is running.
When using the Terminal to communicate with an ULTRA Plus or IQ, any valid Host command may be
entered. Refer to Part 6
