1. Connect Modbus RTU bus as labeled in the above diagram.
2. Connect 12-24 VAC/DC power as labeled in the above diagram.
3. Red power Led should light up.
4. Adjust dip switch for desired operation.
5. Perform a local download on the remote Modbus RTU site.
6. Verify the Rf network communication with the Signal Strength, TX, RX, and Link led indicators.

Note: As with any Rf network, plan ahead for antenna location and placement. It is the intention of AIC Wireless to provide a
reliable wireless communication device for existing Modbus RTU networks. However, in some conditions, reliability is deter-
mined largely by correct antenna placement, which is the responsibility of the installer. Using good judgment in antenna place-
ment will help decrease service related issues and increase reliability. This product is NOT TO BE USED in situations where life
safety issues may arise. AIC Wireless makes no claims, expressed or implied, of the products usefulness with regard to spe-
