Page 34: Flow Control
RV-M7 Technical Manual utilization is only about 50%. But, if the serial port baud rate is set much higher, say 2-8X the over- the air rate, the channel utilization becomes near 100%. Because the M7 can handle serial-port data rate far in excess of the over-the-air rate, the efficiency of the M7 in Packet Mode is approximately the same as other brand modems that cannot operate in a Packet Mode —... -

Page 45: Setting The Over-The-Air Data Rate
RV-M7 Technical Manual Setting the Over-The-Air Data Rate The M7 has programmable over-the-air baud rates. The over-the-air rate is stored in register R2, and is programmed with the ATR2 x command, where x is a number corresponding to the rate. The are many possible baud rates, but not all rates may be used with all radio modem models. - Page 46 RV-M7 Technical Manual Other data rates of 0(800bps), 2(2400bps), 3(4800bps), and 7(9600bps) will work, but have a less optimal bit-error-rate vs. receive sensitivity. RV-M7-UC-W (wide-band version) For high-speed operation, set R2 to 5 (9600 baud). For best range (longest distance), set R2 to 1 (1200 baud) Other data rates of 0(800bps), 2(2400bps), 3(4800bps), 7(9600bps), and 6(19,200bps) will work, but have a less optimal bit-error-rate vs.

The M7 RF modem has built-in compatibility with a radio modem made by Sonik Technologies, Vytek Wireless, and Cal Amp called the SkyLine. In most applications, Raveon’s M7 modem can communicate with SkyLine modems, provided the M7 is properly configured. There are two versions of the Skyline, a wide-band version running at 9600 bps over the air, and a narrow-band version running at 5142bps over the air. - Page 57 RV-M7 Technical Manual Note: The maximum Permissible Exposure (MPE) for this product was computed using a 0dB gain antenna, and must be recalculated if a gain antenna is used.

Page 58: Appendix A. Serial Port Hardware
RV-M7 Technical Manual Appendix A. Serial Port Hardware 15.1 Serial Port Data and Handshaking Signals In computer terminology, the RF modem is considered a “Data Communications Equipment” device, or DCE. The user’s hardware that the modem is connected to is considered “Data Terminal Equipment”, or DTE. -
Page 59: Dtr
RV-M7 Technical Manual On this line the modem indicates to the DTE that it has received a carrier from a remote device. It will assert this signal any time there is a carrier detected. The modem may be configured to assert this when an RF carrier is detected (any on-channel RF, voice or data), assert it only when another RF modem signal is detected, or always assert it. -
Page 60: Null Modem Without Handshaking
RV-M7 Technical Manual 15.2 Null modem without handshaking Sometimes, a “Null Modem” cable may be required to connect the M7 modem to another device. The specific connections are very dependent upon the type of hardware and handshaking used, but the following sections should help in configuring a null-modem cable. -
