Toshiba Perception E Ex Digital Pbx Installation And Maintenance Manual

							IMPORTANT NOTE! 
To use the PDIU-DI or PDIU-DS with AT 
commands, communications software or 
some program that performs “terminal 
emulation”must be loaded in the computer. 
The AT commands cannot be issued from 
the computer’s operating system prompt. 
6.100 Common DIU Connections 
6.101 The block diagram in Figure 4-51 illustrates 
common DIU connections. In this example, PDIU- 
Dls are connected to laptop personal computers 
(PC1 and PC2), and the PDIU-DS’s are connected 
to a serial printer and modems. The PC users can 
transfer files internally, print files on the same 
printer, and access the modem to send/receive 
data to/from an external personal computer, or dial 
up a data service. 
6.102 To access these devices, a data call connec- 
tion must be established between the DIUs. This is 
accomplished by dialing the destination DIU from a 
digital telephone dialpad or from a PC keyboard 
using standard AT dial commands. PDIU-Dls have 
port and DATA DN assignments adjacent to the 
digital telephones that they are connected to, while 
PDIU-DS’s have separate port and DATA DN as- 
signments. The 
q and m buttons on the digi- 
tal telephone tell the system whether a voice or data 
call is being made: The 
q button indicates voice 
calls, and the m button indicates data calls. 
When dialing from a keyboard with AT commands, 
enter 
ATD for data calls. Only DATA calls can be 
made through keyboard dialing. 
6.103 Installation instructions for these devices are 
provided in Paragraphs 6.140 w 6.160. Call paths 
and scenarios for four types of data calls are 
provided in Paragraphs6.181 m 6.185. Step-by-step 
data calling procedures are provided in the PDlU 
User Guide. 
6.110 EIA interface Leads (Signals) 
6.111 Both DIUs operate with the ten standard EIA 
M-232 interface leads (signals) on which signal- 
ing data is transmitted and received. DlUs connect 
to serial data devices’ signals with standard RS- 
lNSTALLATlONlNSTRUCTlONS 
SECTION 200-255-204 
FEBRUARY1992 
232 cables, available from telephone supply stores. 
The PDIU-DVPDIU-DS Data Units require ten sig- 
nals for some applications, but can function with 
sight, using modular cords and connectors with 
RJ45/DB25 adapters for other applications (Fig- 
.rres 4-52 and 4-53). If uncertain which signals are 
iecessary for an application, all ten should be 
connected. 
IMPORTANT NOTES.’ 
1. The PDIU-DI is always a DCE device; 
the PDIU-DS may be a DTE or DCE, 
depending on how its in ternal jumpers 
(1 - 9) are configured (see Figure 4-54). 
2. In the descriptions below, when a sig- 
nal is ON, its potential is about seven 
volts positive, relative to signal ground 
(pin 7); when a signal is OFF, it is about 
7 volts negative, relative to the signal 
ground 
(pin 7). 
Frame Ground (FG, Pin 1): 
The FG 
signal (EIA circuit AA) is a protective or 
safety ground which is bonded to the 
PDIU-DVPDIU-DS. If required by local 
codes, the FG may be connected to 
external ground. 
Transmit Data (TD, Pin 2): DTE devices 
transmit, and DCE devices receive data 
on theTD lead (EIA circuit BA). Before the 
DTE device can transmit the TD signal, 
the RTS, CTS, DSR, and DTR signals 
(all discussed later in this section) must 
be ON. The TD signal is 
OFF in the idle 
state. 
Receive Data (RD, Pin 3): The DCE 
device transmits data to the DTE device 
on the RD lead (EIA circuit BB). 
Request to Send (RTS, Pin 4): Some DTE 
devices send an RTS signal (EIA circuit 
CA) to the DCE device when they are 
ready to transmit data on the TD lead. If 
the DTE device generates the RTS signal, 
the DIU DIP switch 
SWI-4 should be set 
to ON to inform the PDIU. Sometimes, the 
DTUDCE device may use RTSKTS for 
Ready/Busy-type flow control. In these 
cases, DIP switch 
SWl-4 should be set to 
OFF (see Figure 4-55 for the DIP switch 
information).

l Clear to Send (CTS, Pin 5): The DCE 
device sends the CTS signal (EIA circuit 
CB) which indicates that it is prepared to 
transmit data to the DTE device. The 
DCE device sends this signal, only when 
it receives the RTS signal from the DTE 
device. Sometimes, the DTE/DCE de- 
vice may use RTS/CTS for Ready/Busy- 
type flow control; in these cases, dip 
switch SW1 -4 should be set to OFF (see 
Figure 4-55 for the DIP switch informa- 
tion). 
l Data Set Ready (DSF?, Pin 6): When 
connected to the communication chan- 
nel and prepared to exchange control 
characters to initiate data transmission, 
the DCE device sends the DSR signal 
(EIA circuit CC) to the DTE device. If the 
PDIU DIP switch SWl-1 is set to OFF, 
DSR and DCD (see DCD description 
below) will be ON continuously; if the 
switch is set to ON, the PDIU generates 
DSR only after receiving the DTR signal. 
Sometimes, DTE/DCE devices use DTW 
DSR for Ready/Busy flow control; in these 
cases, DIP switch SWl-2 should be set 
to OFF (see Figure 4-55for the DIP switch 
information). 
l Signal Ground (SG, Pin 7): The SG 
signal (EIA circuit AB) establishes the 
common ground reference for all other 
PDIU and data device signals, and must 
be wired for all applications. 
l Data Carrier Detect (DCD, Pin 8): The 
DCE device sends the DCD signal (DCD, 
Pin 8) when receiving the carrier signal 
on the line side. Before transmitting or 
receiving data, most DTE devices re- 
quire that the DCD be ON. If the carrier 
signal is removed by the remote end or 
lost due to a fault condition on the line, 
the DCE notifies the DTE device by an 
OFF condition with the DCD signal. To 
set the DCD on continuously, PDIU DIP 
switch SW1 -2 is set to ON; if set to OFF, 
the DCD signal will be on during the communication state only. SWl-2 is set 
to OFF when the DTE/DCE uses the 
DTFUDSR signals for Ready/Busy flow 
control(seeFigure4-55fortheDIPswitch 
information). 
l Data Terminal Ready (DTR, Pin 20): 
The DTE device sends the DTR signal 
(EIA circuit CD) to the DCE device, 
prompting the DCE device to open the 
communication line. The line is closed 
and the call disconnected when the DTE 
device quits sending the DTR signal. 
DTR may be sent any time to indicate 
that the DTE is ready to transmit or re- 
ceive data. Sometimes, DTE/DCE de- 
vices use DTWDSR for Ready/Busy flow 
control; in these cases, DIP switch SWI- 
2 should be set to OFF (see Figure 4-55 
for the DIP switch information). 
l Ring Indicator (Rl, Pin 22): The RI 
signal (EIA circuit CE) is sent by the DCE 
device to the DTE device. Whenever the 
DCE device receives a ringing signal on 
the line side, it turns the RI signal on. If 
PDIU DIP switch SWI-3 is set to ON, the 
RI signal will be on continuously; if the 
switch is set to OFF, the RI signal will be 
one second on/three seconds off.

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:

6.140 PDIU-DI to Personal Computer (PC) 
Installation 
6.141 The PDIU-DI always functions as a DCE 
device; it transmits data on the Receive Data lead 
(RD) and receives data on the Transmit Data lead 
(TD). Most personal computers function as DTE 
devices; PCs transmit data on the TD lead and 
receive data on the RD lead. Follow the steps below 
to install the PDIU-DI to a DTE or DCE PC: 
NOTES: 
1. 
2. 
1) 
2) 
Use the steps below when installing an 
ASCII terminal, orany other DTE device to 
a PDIU-DI. 
The PDIU-DI can connect to a DCE com- 
puter or any other DCE-type device using 
a specially configured M-232 cable or 
adapter; however, this applica tion is rarely 
required. 
lnstall the digital telephone that is to be 
aquipped with PDIU-DI in accordance with the 
i nstructions in Section 200-255-205, MDF 
Jrrangement, Paragraph 1.01 and in Figure 
5-2. 
nstall the PDIU-DI in the digital telephone’s 
)ase in accordance with the instructions in 
‘aragraph 6.130. 
NOTE: 
The PDIU-DI operates only as a DCE device; 
therefore, unlike the PDIU-DS, it has no inter- 
nal jumpers. 
3) Connect the appropriate RS-232 cable be- 
tween the PDIU-DI DB-25 female connector 
and the PC’s appropriate asynchronous serial 
communications port connector. 
IMPORTANT NOTE! 
Check the PC manufacturer’s serial com- 
munication port interface documentation

SECTION 200-255-204 
FEBRUARY1992 
for correct RS-232 pin requirements; re- 
quirements vary with each manufacturer. 
The number of EIA RS-232 signals re- 
quired (8,9, or 10 wires) will depend on the 
application. When EIA signal requirements 
are not known, connect the 10 EIA signals 
listed in Paragraph 6.110. Figures 4-57,4- 
58, and 4-59 provide diagrams for con- 
necting RS-232 cables between PDIU-Dls 
and a Toshiba printer and laptop com- 
puter, IBM XT-type and A T-type personal 
computers. 
4) 
5) Set the PDIU-DVPDIU-DS DIP switch (SWl- 
1 - 4) for the desired application. Figure 4-55 
shows the DIP switch locations and Para- 
graph 6.120 describes the switch functions. 
Access the DEKT and DDIU Programs for 
PDIU port connection and data button assign- 
ments. 
l The port number entered for the PDIU-DI 
in the DDIU Program is the adjacent port 
number of the digital telephone. 
Example: DKTportnumber= L024, PDIU- 
DI port number = LO34 
IMPORTANT NOTE.’ 
The eighth port (circuit) of the NDKU can- 
not be used for data switching connections 
(PDIU-DI or PDIU-DS). 
6.150 PDIU-DS To Printer Installation 
6.151 PERCEPTIONeLex enables serial printers 
(laser, dot matrix, or other types) to be connected 
to stand-alone data interface units (PDIU-DS). 
Digital telephones equipped with PDIU-DI and 
Electronic Telephones equipped with DDIU-MAT 
can share access to these printers. Serial printers 
operate as DCE or DTE devices, depending on the 
vendor. The PDIU-DS can be connected to either 
type, since it can be configured as a DTE or DCE 
device. (The PDIU-DS comes from the factory 
configured as a DCE device.) Follow the steps 
below to install the PDIU-DS to a serial printer.
