6.120 DIP Switch Options
6.121 Each of the PDIU-DI and the PDIU-DS data
units has a four-control DIP switch which can be
configured for signaling options. The switch is
located on the bottom of the PDIU-DI, and on the
back panel of the PDIU-DS (see Figure 4-55).
l
SW1 -1: Normally, this switch is set to OFF. When
set to ON, it automatically disconnects devices
from the PDlUs if no data is exchanged between
the devices and PDIU for an interval of eight to
nine minutes.
l
SWl-2: This switch is placed in the ON position
when the PDIU-DI (or PDIU-DS configured like a
DCE) must hold DCD and DSR on continuously.
Sometimes, a computer may use DTR/DSR for
Ready/Busy flow control; in these cases, this
switch should be OFF. Consult the DTE/DCE
device or application software documentation to
determine which type of flow control is required.
l
SWl-3: The PDIU-DI (or PDIU-DS configured as
a DCE) sends the Ring Indicate signal (RI) to the
computer to tell the computer (DTE) that the
PD.lU is receiving an incoming call. SW1 -3should
be set to ON for the DCE to send RI continuously,
and OFF to send at one-second-ON/three-sec-
onds-OFF intervals. Consult the DTUDCE de-
vice or application software documentation to
determine which type of flow control is required.
l
SWl-4: This switch is placed in the ON position
if the computer does not output the RTS signal.
Sometimes, the computer may use RTS/CTS for
Ready/Busy flow control; in these cases, SW1 -
4 should be OFF. Consult the DTE/DCE device
or application software documentation to deter-
mine which type of flow control is required.
6.130 PDIU-DI INSTALLATION
6.131 The PDIU-DI (Figure 4-56) mounts directly
on the bottom of a digital telephone (forming a
single unit) as follows:
1) Remove the digital telephone base (see Para-
graph 6.12).
2) Replace the telephone base with the PDIU-DI.
