Lode BV Excalibur Sport
40
The setting of the RS232 port when the LODE 38k4 PROT is used:
Baud rate : 38400
Parity : none
Data bits : 8
Stop bits : 1
The setting of the RS232 port when the LODE WLP protocol is used:
Baud rate : 9600
Parity : even
Data bits : 7
Stop bits : 2
The settings belong to each protocol. The other protocols have their own specific settings.
The RS232 signals CTS, DCD and DSR are hardwired within the Excalibur Sport. The RS232
signals RxD and TxD are isolated through opto couplers from the Excalibur Sport itself. The
interface part has its own galvanic isolated supply.
8.4 Analog in/out
This connector can be used to connect the Excalibur Sport to other analog controlling
instruments.
Note: analog workload input is only active if the Excalibur Sport is in Analog Mode.
Analog in/out specifications:
! Readout RPM 1V = 100 RPM
! The workload scaling is selectable, see specifications:1V ^ 100 W, 1V ^ 200 W, 1V ^
500 W. The input voltage is limited to maximal 5V. Do not exceed this limit.
! The maximal voltage at the analog workload output is maximal 10V. The load scaling
adjustment holds both for load input and output.
Note for analog control: With digital control the set workload is exact defined. An analog
signal can in principle take every value and it is more sensitive for noise than digital. This can
give rise to a small error. In the ergometer it is converted to a digital value and rounded to
watts. The actual workload is that one indicated on the ergometer.
