Low Power
Modem
MICRO‑AIDE's Low Power Modem (LPM) is used by nearly every DOT in the country. Unlike commercial modems, the LPM is designed to operate in harsh environments as typically found in most roadside applications. While in standby mode, the LPM's extremely low current draw makes it an ideal device in solar power applications. Numerous profiles allow the LPM to work with a variety of vehicle counter and weigh-in-motion products.
Limited
Distance
Modems
In applications where copper pairs are embedded alongside the roadway, the MICRO‑AIDE Limited Distance Modem (LDM) products are an ideal communications solution. They can facilitate RS-232 communications over simple twisted pairs at distances exceeding several miles. Their completely asynchronous design provides operation from 300 to 19,200 baud. Point-to-point and multi-drop networks are supported.
Indication
Support
Devices
MICRO‑AIDE's Indication Support Devices are used primarily in lane control applications. Both the HACS and LOD-1 operate as light out detectors in LED and incandescent applications, respectively. The RLS is a relay-based load switch that is ideally suited to low current LED applications.
Local
Control Unit
The TLCU is a legacy product still used by the Texas DOT. Its 192 optically-isolated inputs and outputs can be connected to a variety of vehicle sensor, signal and lane control products. A pair of RS-232 ports provide both local and remote communications and diagnostic capabilties.
