Hooking Up The Modem
Sending status notifications and alarms via satellite can be accomplished by hooking up the satellite modem to the MODBUS/RS-485 port of the RIO xR3.
Optima recommends installing a zener barrier or surge protector wherever the wiring leaves the shelter for added safety.
The examples below depict how to power the satellite modem from the built-in power supply, or an external source.
Using the built-in source has the added advantage that the power output is backed up by the built-in standby battery.
This allows sending a ‘last gasp’ message before everything shuts down in case of prolonged power outages.
Satellite modem and MODBUS devices can be mixed and matched on the same bus.
Mounting The Modem
Follow these simple recommendations when mounting the modem:
- Affix the satellite modem to the mounting bracket, using the supplied hardware.
- Mount the bracket to a pole or cell tower.
- The modem requires an unobstructed view of the sky.
- Do not mount indoors.
- Do not install close to tall buildings, solid structures or trees.
- Use supplied bracket for easier installation.
- Ensure to mount the modem on a level plane.
- Do not affix to walls or under roof overhangs.
- Fill connector with gel to create a water tight seal.
- Securely attach the outdoor cable to the satellite modem.
