Communication
The serial DB9 (female) is wired so that it is not necessary to use a null cable with a cellular
modem. This means that standard local serial communication would require a null adapter.
However, it is anticipated that local communication will be with USB (male DB9). The change
in the serial DB9 also means that cables used with the Mini-Seis are not compatible with the
Mini-Seis III Pro.
The male DB9 connector is for USB data transfer. There are two USB cables supplied. One
cable is for computer communication, the other cable is for data transfer to a USB thumb
drive. While we have tested many thumb drives, it is possible that not all USB thumb drives
will function with the Pro. White recommends avoiding low priced generic cables in favor of
known brands. Mini-Seis III USB cables are not compatible with the Pro and vice versa.
Charging
The standard instrument will contain a sealed rechargeable lead acid battery. The Mini-Seis
III Pro has circuitry which helps prevent overcharging. It is harder on the internal battery to
let it discharge than to keep it charged.
