NOTES
1. For more information, see the instructions preceding the record sheets. Copy this page if more than three D/Us are installed.
2. Initialized data: LED 17 ON, all others OFF.
3. Auto pause will be inserted after a Centrex or PBX access code is dialed by a DIU: CO line must be assigned in Program
42-O and must have access code assigned in Program 42 (1 - 8). Pause time is determined by Program 12-3. A pause will
also be inserted after the DK CO line access code is dialed (by the DIU) in all cases if LED 05 is turned on.
4. DlUs can connect to any digital circuit in the Base Unit and on the PDKUZ and KCDU, but it can only connect to Circuits 1
- 7on the PDKUl.
5. If a PDIU-DS is connected to a modem, turn LED 06 ON to cause the modem to disconnect the line when the user presses
the Data Release button. Modem should be sent AT Command ‘AT & 02” so it can recognize DTR pulse, and the PDIU-DS
SWI-2 switch must be off (in the up position). This feature is for outgoing modem calls only-DTR will not pulse on incoming
modem calls. Always change the modem escape sequence from “+ + +” to some other character using the “ATSZ=-”
command; this allows AT commands to be sent to the modem or DIU independently.
6. The PDIU-DI connects to IOOO-series Digital Telephones, and the PDIU-Dl2 connects to ZOOO-series Digital Telephones.
