Connection Points For The Data LinkNote: These descriptions are for the EMCP II+ for applications with the EUI.There are four serial data links. The preceding illustration shows the connection points at the GSC+. The data links provide the means for the GSC+ in order to communicate with other devices. The data links are defined in the following list:ALM Data Out - This serial data link is a single directional link. The GSC+ uses this data link for one-way communication with the optional Alarm Modules (ALM) or with the optional Customer Interface Module (CIM). The data link for the ALM consists of a single wire that connects the GSC+ (connector contact 35) to an ALM or CIM. A return connection between the GSC+ and the module is also required. For more information, see Systems Operation, "Alarm Modules" or Systems Operation, "Customer Interface Module".RDM Data Out - This serial data link is a single directional link. The GSC+ uses this data link for one-way communication with the optional Relay Driver Module (RDM). The RDM data link consists of a single wire that connects the GSC+ (connector contact 30) to the RDM. A return connection between the GSC+ and the module is also required. An RDM is used in conjunction with the optional Customer Communication Module (CCM). For more information, see Systems Operation, "Relay Driver Module". CAT Data Link (ECM) - This serial data link is bidirectional. The GSC+ uses this data link for two-way communication with the engine ECM. The CAT data link consists of a cable that connects the GSC+ (connector contacts 19 and 20) to the engine ECM. The GSC+ expects to receive the data from the engine ECM on these pins. Customer Communication Module (CCM) Data Link - This data link is also bidirectional and the data link connects the GSC+ to the Customer Communication Module (CCM). The second CAT data link allows eight generator set controls to be connected. The GSC+ expects to receive data from the CCM on these pins.
