iHP Manual 36 | P a g e
User Configurable Commands – Commands that can be configured based on the user operation
requirements. The user configurable commands are the commands that can be read or written by the
user.
Notes for Module User Configurable Command:
The user needs to send the save command (Using ISOCOMM command D7h) in order to retain the
command on the next power-up. ISOCOMM command is required to change the module’s D3h
(MODULE_CONFIG), B5h (MODULE_VRISE_TIME), B6h (MODULE_IRISE_TIME). When the user
sends these commands, the setting will be AutoSaved to the module and there is no need to send
a separate save command.
Manufacturer Commands – Commands used by the manufacturer. The user is not allowed to use
these commands.
Read-Only commands – Commands for iHP system reporting and fixed configuration settings. The
user can only read these commands.
Voltage, current, power, and temperature reporting
Status reporting
Fixed configuration settings
Special Command – Commands that have special function in the operation of the iHP system.
3.3 Interval Between User Commands
To communicate properly there should be a time interval between user commands.

3.4 Ethernet Communication
The iHP Ethernet connection can support up to 10/100Mbps link speed. The iHP IP setting can be configured
to static IP or Dynamic Host Configuration Protocol (DHCP). By default, the Ethernet communication is set to
DHCP, which requires connection with a router to assign an IP address.
If a router is not being used, the iHP will not have an IP address to allow communication, so the user will need
to use the LAN RESET button to set the iHP to known state, which is static IP with IP address of 192.168.2.100.
