4.1 Data Rate Option (1)

The data rate can be set by the client for installations where the FMP software must gen-

erate the data clocking signal. If external clocking is provided by a modem or modem

eliminator, the conﬁguration of the data rate is not required. However, when transmit-

ting data, the data rate setting is used to calculate the amount of time to wait before

aborting a transmission with the

DLI_ICP_ERR_XMIT_TIMEOUT transmit timeout error.
