Page 114 Channel configuration Chapter 9 9.7.11 Set sampling rate Each channel of the D telemetry system is assigned the same sampling rate (except for the additional channels Reference Temp. and Supply Voltage). If you want to change the sampling rate of the D telemetry system, each D -SCT transmitter unit must be reprogrammed individually.
Page 115 Channel configuration Chapter 9 For example: When configuring 2 D -SCT 868 MHz transmitting units, the first D -SCT is assigned 3 channels, the second only 1 channel. The higher number is decisive. This results in a maximum sampling rate of 1200 Hz. When configuring via a web browser, click Set to apply the settings.
