PN-CK00 (PLO)

Note 1: When the power is on, flip the MB switch ON (UP position) before plugging/unplugging the circuit card.

Note 2: When using this card, set the SW2 switch on the PN-CP00/PN-CP00-B/PN-CP03 (MP) as follows.

SW2-2: OFF

SW2-3: ON

Note 3: When using this card for providing a master office clock signal, set the SW0 switch on the PN-CK00 and the SW switch on the PN-24DTA/PN-24DTA-A or the PN-30DTC/PN-30DTC-A mounted in PIM0 as fol- lows.

• PN-CK00 card	• PN-24DTA/PN-24DTA-A card	• PN-30DTC/PN-30DTC-A card
SW0-1: OFF	SW-1: OFF	SW-1: OFF
SW0-2: OFF	SW-2: OFF	SW-2: OFF
SW0-3: OFF
SW0-4: OFF
SW0-8: ON

Note 4: When using this card as a sub-master, set the SW0 switch on the PN-CK00 and the SW switch on the PN-24DTA/PN-24DTA-A or the PN-30DTC/PN-30DTC-A as follows:

For 1.5MHz interface:
• PN-CK00 card	• PN-24DTA/PN-24DTA-A card
SW0-1: OFF	SW-1: ON
SW0-2: ON	SW-2: OFF
SW0-3: OFF
SW0-4: ON*
SW0-8: ON

*Set to ON, when more than one DTI card is mounted in PIM0, or set to OFF when only one DTI card is mounted in PIM0.

For 2MHz interface:
• PN-CK00 card	• PN-30DTC/PN-30DTC-A card
SW0-1: ON	SW-1: ON
SW0-2: ON	SW-2: OFF
SW0-3: ON
SW0-4: ON*
SW0-8: ON

*Set to ON, when more than one DTI card is mounted in PIM0, or set to OFF when only one DTI card is mounted in PIM0.
