Can SYNEL terminals be used on their own or do they require a host computer?
SYNEL SY-XXX series terminals have the ability to collect, validate and store transactions as an off-line, or ‘stand-alone’ unit, provided they are equipped with batteries. These terminals can perform in on-line mode (with host validation), off-line mode (batch processing), and/or a combination of both. In the off-line mode, if the terminal cannot communicate with the host, it automatically validates and stores transactions internally. When a transaction cannot be validated locally it will request validation directly from the host database, and reject the request if the host is not available. When host communications are re-established, the terminal can be configured to automatically send the stored transactions to the host. In an on-line mode, all transactions performed at the SY-XXX series terminals will be sent immediately to the host for validation, processing, and return messaging.
