With thisfunction, Port 1 ~ Port 8 are customized whenselecting devices to install. NoneYou can program Port 1 ~ Port 8. KDS-100You can program the KDS-100 when connecting itto the TK-7100H/8100H using CN2/CN3.Configurations of External Devices and theKDS-100, are the same when configuring Port 1 ~Port 8 with the value set at the KDS-100 even ifthe External Devices is None.Refer to Section “15 KDS-100” for details. KGP-2A/2BYou can program the KGP-2A/2B whenconnecting it to the TK-7100H/8100H usingCN2/CN3.The programming of External Devices and theKDS-100 are the same when configuring Port 1 ~Port 8 with the value set at the KGP-2A/2B, even ifthe External Devices is None.Refer to “16 KGP-2A/2B” for details. SmarTrunkYou can program the SmarTrunk ST-865KW4when installing it using CN4.The SmarTrunk does not activate when theExternal Devices is None.Refer to Section “17 SmarTrunk” for details. ScramblerYou can program the Scrambler Board whenconnecting it to the TK-7100H/8100H usingCN2/CN3.The programming of External Devices and theKDS-100 are the same when configuring Port 1 ~Port 8 with the value set at the Scrambler Board,even if the External Devices is None.Note: You can connect the KDS-100 and KGP-2A/2B to thesame terminal. Therefore, you can connect theKDS-100 when the KGP-2A/2B is selected, and viceversa.
