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" protocol.
Protocol description is available in BK Precision User Manual (for 8500 series DC electronic loads).
