The ITECH IT8511+ is a programmable DC electronic load (150W 0~30A 0~120V) with TTL (serial) connectivity.
See ITECH IT8500 series for information common to all devices in this series.
NOTE! DB9 connector on this device is not RS-232, but non-isolated TTL-serial connection. To connect load safely to a computer,
an isolated TTL to RS232/USB interface is needed.
Hardware
TODO...
Protocol
Early units support only proprietary binary protocol, while apparently newer units have updated firmware that supports also SCPI "style" protcol.
