In this Sim26-44, set the channel (A channel) where the SCSI cable will be
connected to 1 (SC PRINTER).

already been completed,the above operation is not necessary. That is, the channel
where the printer kit has already been connectedautomaticallybecomes a channel
for the SCSI cable.

*2) If the ICU ROM installed in the ROM Writer is version 3.xx for the AR280/285/
335 or any version for the AR250/286/336/405, the OPE and PCU ROMs
need not be installed on the machine when the program data is written to the flash
ROM, and the versions of the OPE and PCU ROMs can be upgraded separately.
If the ICU ROM installed in the ROM Writer is version 2.xx for the AR280/285/
335, the OPE and PCU ROMs should be installed on the machine when the
program data is written to the flash ROM. Therefore,be sure to upgrade the ICU
ROM version first, and then upgrade the versions of the OPE and PCU ROMs
using the upgraded ICU ROM.
