Main Functions Main functions are as following： 1. Wireless receiving function. The host can receive the signals from call button and palm transmitter with feature code, and transmit the message to corresponding pager. 2. The pager has to be MMC-NC-8E, which can display numeric and english message. 3. Text preprogrammed function. The paging unit, such as, table, room, bed etc. and the paging category such as call, bill, water can be preprogrammed to the host and related with corresponding call button. When the button is pressed, the pager will display a complete message, such as Table No.5 calls for service. 4. Repage function. Repage times and interval can be setup between the waiter and his directors. If repaging is not finished yet while you cancel it, the message already sent will be automatically deleted. 5. Palm transmitter can be used for dispatching or urging dishes function. 6. Software sending message function. With computer software, the preprogrammed message can be edited to page the programmed pager for interior staff management. 7. Monitoring function. Connected directly with the computer through USB interface, it can monitor the messages from call buttons and palm transmitters for evaluating staff’ working efficiency. If the installation position of the host can not be connected with the computer, the monitor box can be used for the monitoring function. 8. USB data download and upload , program update function available. 5. Software setup Before using the paging host, please first setup the host parameter, pager, call button and palm transmitter. Use the CA software to edit and download the information. The software communication with the paging host is USB mode. Notes: While using, USB can not power on the host, so please connect it with power supply. Otherwise the transmitting and receiving function can not be used. 5.1 Function Introduction The software interface as picture 5.1 shows, mainly includes pager list, palm transmitter list, call button list and manual send data. In the setup column, there are file, system setup, read data, download data. Picture 5.1 TA Software Interface 1、File As picture 5.2 shows, it’s mainly the database operation, including New file, Open, Save as, Delete and Exit. Notes: There should be a database while using the software. For the first time use, it’s necessary to setup a new database, you can choose TA or CA database. The two kinds of database are not compatible with each other. Picture 5.2 File 2. System Setup System setup including initialization, host parameter, program update, call type registration and pager check time. Picture 5.3 System Setup （1）Initialization It will initialize all the host parameters. （2）Host Parameter Host parameter as picture 5.4, room No. Switch is temporarily invalid, the monitor function needs to work with monitoring software, it can be setup as transmitting data, USB passback, net page passback(customization required), among which transmitting data monitor needs to setup pager receiver No., other modes do not need to setup the No. Repage setup, it can setup the pager and its director repage times and interval. Transmission mode, there are two modes: inner transmission mode and 485 output, this is valid only for CA. For …
