These functions are determined by the corresponding EEPROM / Register setting. Therefore the operations
of “
“ depend on the user’s setting.
*2
In Burst mode setting (RE_BURST_SET
“1”, RE_SFP_SET
”1”), it is assumed that only APC_FF
function is used and no APC_FB function is used (Monitor PD, CURRALM and OPTALM are not used).
[*3] Setting of RE_SFP_SET
“0” and R_PWR_LVL1_SET
“1“ is prohibited.
