Understanding Write Protection; Table 39: Write Lock - Honeywell SLG 700 Option Manual

7.7 Understanding write protection

The hardware and software write lock features are controlled using the FEATURE_SEL
parameter in the resource block. The software write lock feature can be enabled, only if the
hardware write lock feature is disabled. If the software write lock feature is enabled without
disabling the hardware write lock feature, then the software write lock feature gets disabled
automatically. The hardware write lock feature must be enabled before placing the hardware write
lock jumper in the On position. If the hardware write lock feature is selected with the hardware
jumper being enabled, the selection is rejected. See Figure 37 for jumper location.
For more information on write protection, see Table
