5 Communications
5.1 RS232 Communications
Communication with TideMaster is via the TideMaster Express software. The unit can also be interrogated
by a terminal program such as HyperTerminal. Details of the commands that can be manually sent and
received are provided in Section 9
The data cable supplied with the TideMaster is terminated with a 9 pin serial connector. If no serial port is
available on the host PC then a USB-Serial adaptor is supplied with the unit.
Communication parameters are factory set to 115200 Baud, 8 data bits, 1 stop bit, no parity.
5.2 Bluetooth Communications
The TideMaster is also fitted with a Bluetooth communications chip. The system allows a wireless link to be
established between an instrument and the operator's PC, performing exactly as if the instrument were
connected to the PC via a serial cable.
Before Bluetooth communications can be established it is necessary to pair the TideMaster with the PC to be
communicated with. A TideMaster can be paired with multiple PC's but can only be connected to one PC at
a time.
Bluetooth communication will seriously deplete the battery lifetime.
It is recommended that unless mains powered, Bluetooth connections are disconnected when not
required
