Table 4.4-1 lists the errors which are specific to a request. For example, LJE_INVALID_CHANNEL_NUMBER. If this error occurs, other requests are not affected.
Table 4.4-2 lists errors which cause all pending requests for a particular Go() to fail with the same error. If this type of error is received the state of any of the request is not known. For example, if requests are executed with a single Go() to set the AIN range and read an AIN, and the read fails with an LJE_COMM_FAILURE, it is not known whether the AIN range was set to the new value or whether it is still set at the old value.
