For example, if Master Packet Repeat = 3, the radio will wait for 6 slots, gathering ...16With a setting of 2 and higher, the radio will wait for a number of slots calculated by the following formula:17(Modbus RTU Setting + Master Packet Repeat Setting + 1) x 217For example, in a radio where the Modbus RTU setting = 2 and the Master Packet Repeat setting = 3, the radio will wait for (2+3+1) x 2, or 12 slots.17Call Book18Radio Transmission Characteristics19Edit Radio Transmission Characteristics19Setting Xmit and Rcv Frequencies19(1) and (2) Max Packet Size and Min Packet Size19(3) Xmit Rate20(4) RF Data Rate20(5) RF Xmit Power21(6) Slave Security21(7) RTS to CTS21(8) Retry Time Out22(9) Lowpower Mode22Important Notes23(A) High Noise23(C) Remote LED23MultiPoint Parameters24Edit MultiPoint Parameters24(0) Repeaters24(1) Master Packet Repeat24(2) Max Slave Retry25(3) Retry Odds25(4) DTR Connect25(6) Network ID25(8) MultiMaster Sync25(9) 1 PPS Enable/Delay25(A) Slave/Repeater26(B) Diagnostics26(C) Subnet ID26The respective Subnet ID diagram and settings are shown below.27(D) Radio ID27(E) Local Access27(G) Radio Name27Radio Information28Number of Disconnects28Antenna Reflected Power28Average Noise Level28Average Signal Level29Overall Rcv Rate (%)29Radio Temperature29Operational RS-422 and RS-485 Information31RS-422 and RS-485 Full Duplex Pin-Outs32RS-485 Half Duplex Pin-Outs32RS232 Pin Assignments32RF Board Pinout33FreeWave Technical Support33Errata38Firmware Version 1.7038Firmware versions 1.67o and lower38Размер: 562,6 КБСтраницы: 38Язык: EnglishПросмотреть
