Abstract

This specification describes the functionality of an XFS compliant Cash-In Module (CIM) Service Provider. It defines the service-specific commands that can be issued to the Service Provider using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions.Persistent values are maintained through power failures, open sessions, close session and system resets.This specification covers the acceptance of items. An "item" is defined as any media that can be accepted and includes coupons, documents, bills and coins. However, if coins and bills are both to be accepted separate Service Providers must be implemented for each.All currency parameters in this specification are expressed as a quantity of minimum dispense units, as defined in the description of the WFS_INF_CIM_CURRENCY_EXP command.There are two types of CIM: Self-Service CIM and Teller CIM. A Self-Service CIM operates in an automated environment, while a Teller CIM has an operator present. The functionality provided by the following commands is only applicable to a Teller CIM:WFS_CMD_CIM_SET_TELLER_INFOWFS_INF_CIM_SET_TELLER_INFOIt is possible for the CIM to be part of a compound device with the Cash Dispenser Module (CDM). This CIM\CDM combination is referred to throughout this specification as a “cash recycler”. For details of the CDM interface see [Ref. 3].If the device is a cash recycler then, if cash unit exchanges are required on both interfaces, the exchanges cannot be performed concurrently. An exchange on one interface must be complete (the WFS_CMD_CIM_END_EXCHANGE must have completed) before an exchange can start on the other interface. The WFS_ERR_CIM_EXCHANGEACTIVE error code will be returned if the correct sequence is not adhered to.The CIM interface can be used for all exchange operations on cash recycle devices, and this interface should be used for cash units of multiple currencies and/or denominations (including multiple note identifiers associated with the same denomination).The event WFS_SRVE_CIM_COUNTS_CHANGED will be posted if an operation on the CDM interface affects the recycle cash unit counts which are available through the CIM interface.The following commands on the CDM interface may affect the CIM counts:WFS_CMD_CDM_DISPENSEWFS_CMD_CDM_PRESENTWFS_CMD_CDM_RETRACTWFS_CMD_CDM_COUNTWFS_CMD_CDM_REJECTWFS_CMD_CDM_SET_CASH_UNIT_INFOWFS_CMD_CDM_END_EXCHANGEWFS_CMD_CDM_CALIBRATE_CASH_UNITWFS_CMD_CDM_RESETWFS_CMD_CDM_TEST_CASH_UNITSXFS 3.40 has been designed to minimize backwards compatibility issues. This document highlights the changes made to the CIM device class between version 3.30 and 3.40, by highlighting the additions and deletions to the text.
