Command Descriptions
You can use the ASCII commands, provided in this chapter, to configure,
check errors, and reset the Aries drive through a terminal emulator. A
terminal emulator, however, is not required, Instead, you can use the Aries
Supp0ort Tool software to perform the same operations.
Note: The Aries Support Tool does not support the CMDDIR and ADDR
commands. You must use a terminal emulator to set the commanded
direction and address of each drive.
Before you can communicate with the Aries Drive, you must configure your
terminal emulator. You can use HyperTerminal or an equivalent terminal
emulator, For more information about setting up communications, see “RS-
232/485 Communications” on page 74

The ADDR command configures the unit address for an RS-485 multi-drop
network. The factory default address for an Aries drive is zero (0). The ADDR
command allows you to uniquely address up to 255 units (99 unit maximum
on a single network).
After establishing a unique address for each Aries drive, you can address
commands to specific units. To do this, prefix the command with the unit’s
address followed by an underscore ( _ ). For example, 2_ERES reports the
resolution on unit 2.
RS-485 Multi-Drop
You must address each unit before adding it to the multi-drop network.
For example, you want to set up a 4-unit multi-drop network, where the
drives are addressed as units 1 through 4. After addressing a drive, you
can install it in the multi-drop network.
1. Connect the drive to become unit 1. Through a terminal emulator,
send the following command: Ø_ADDR1
2. Connect the drive to become unit 2. Through a terminal emulator,
send the following command: Ø_ADDR2
3. Connect the drive to become unit 3. Through a terminal emulator,
send the following command: Ø_ADDR3
4. Connect the drive to become unit 4. Through a terminal emulator,
send the following command: Ø_ADDR4
If you need to replace a unit in the multi-drop network, connect to the
individual device and send the Ø_ADDRi command, where “i”
