WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or
death. This device does not include the self-checking redundant circuitry necessary to allow its use in
personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized
sensor output condition.
CAUTION: Never Operate 1 Watt Radios Without Antennas
To avoid damaging the radio circuitry, never power up Sure Cross
Watt) radios without an antenna.
Setting Up Your MultiHop Network
To set up and install your wireless MultiHop network, follow these steps:
1. If your radios have DIP switches, configure the DIP switches of all devices. For DIP switch configurations, refer to the
product's datasheet.
2. Connect the sensors to the MultiHop radios if applicable. For available I/O, refer to the product's datasheet.
3. Apply power to all devices.
4. If your MultiHop radio has rotary dials, set the MultiHop Radio (Slave) ID. If your MultiHop radio has no rotary dials,
continue to the next step.
5. Form the wireless network by binding the slave and repeater radios to the master radio.
6. Observe the LED behavior to verify the devices are communicating with each other.
7. Configure any I/O points to use the sensors connected to the Sure Cross devices.
8. Conduct a site survey between the MultiHop radios.
9. Install your wireless sensor network components.
For additional information, refer to one of the following documents:

MultiHop Register Guide (End User Edition):
Configure the DIP Switches for Master, Repeater, or Slave Mode
Before beginning operation, select one radio to be the master radio. Set the other MultiHop radios to operate as either repeaters
(default setting) or slaves.
1. Remove the top covers of the MultiHop radios.
2. Set one unit to be the master radio.
3. Set the other MultiHop radios to be repeaters or slaves.
4. Set additional DIP switches now.
(See the DIP switches section of your specific devices' datasheets for the positions and descriptions. Battery-powered
radios may have different DIP switch settings than shown below.)
