Chapter 3 - Connecting and Installing Your Impulse

Daisy-Chaining Impulse Drives

Your Impulse also supports daisy chaining. The unit address (range 1-99) can be set via the keypad or in Application Developer.

Rules for Daisy Chain Operation

1.Units on a daisy chain must be “device addressed’ (numbered) in order for communications to work properly. A unit’s address should increment upward as you move down the daisy chain from the PC (see illustration below).

2.Do not duplicate unit addresses.

3.Any loose RS-232C connections or miswiring along the daisy chain will cause communications to fail. Please double check wiring if communication problems arise.

4.Please call IDC if you need to daisy chain more than 99 drives.

5.The hardware diagram below shows how to connect the daisy chain.

If you will be “multi-dropping” Impulse drives with RS485, add 120-ohm termination resistors across RX and TX connections of the last unit as shown below:
