RAMP Modules Vermeer Corporation RAMP (Range Amplified MultiPoint) modules are designed to provide robust wireless communications for any number of applications requiring a wireless transport for serial data. RAMP modules feature a Frequency Hopping Spread Spectrum (FHSS) protocol for excellent interference and multipath immunity. RAMP modules server/client architecture allows for more than 16 million clients to be addressed and communicating within the network.

Reset – Controlled by the RADIO APPARATUS for power-on reset if left unconnected. After a stable power-on reset, a logic low pulse resets the transceiver. Error! When logic Low, the transceiver interprets incoming OEM host data as command data. When logic High, the transceiver interprets OEM host data as transmit data.

Hardware Interface Pin Descriptions RXD and TXD The RADIO APPARATUS accepts 3.3 VDC TTL level asynchronous serial data from the OEM host via the RXD pin. Data is sent from the transceiver, at 3.3 volt levels, to the OEM host via the TXD pin. Pins should be left floating or high when not in use. Leaving the RXD tied low results in the radio transmitting garbage serial data across the RF.
In_Range The In_Range pin is driven low when a client radio’s frequency hopping is synchronized with that of a server. In_Range is always driven low on a server. Following boot, In_Range transitions low in approximately 12 milliseconds on a server. For a client, the In_Range takes an average of 500 milliseconds; this time is dependent on the signal strength of the received beacon, the presence and strength of interference, and randomness of the sync function.
Reflow Parameters Vermeer Corporation’s surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB. Ultimately, it is the responsibility of the customer to choose the appropriate solder paste and to ensure oven temperatures during reflow meet the requirements of the solder paste. Vermeer Corporation’s surface-mount modules conform to J-STD-020D1 standards for reflow temperatures.
