Program 20: Port 04. LEDs 01, 02, 03, 04, 06, and 17 ON; all other LEDs OFF.

Program 21: Digital port 04 assigned with PSTU port 08.

Program 39: Port 00. Data Call (56),

Data Release (54), and Modem (55) buttons should be provided.

Program 81: Port 08. LED 01 ON (CO line 01 rings QSTU/KSTU port 08).

Internal modem: set to auto answer (S0=1).

Default settings for PDIU-DI and PDIU- DS, S-Registers.

2)Make sure PC 1 and PC 2 are on-line with a communications software package and that the communication parameters of each PC and communication software package are set to the same values (data transmission rate, parity, data bits, stop bits, flow control, etc.).

3)From PC 2’s keyboard, type A T D T 5 8 3 3 7 0 0 and press ENTER.

The external modem originates the call to STRATA DK16 CO line 01.

CO line 01 rings incoming to the internal modem (QSTU or KSTU port 08).

The internal modem rings and auto an- swers; the modems handshake and es- tablish communications.

If the modems send result codes, the PC’s screens display, CONNECT XXXX, where XXXX is the data transmission speed set by the communications soft- ware.

At this time, PC 2 is connected to PDIU- DS (14), as shown by the thick lines above (PDIU-DS 14 is in the command mode). PC 2 can now issue AT com- mands to PDIU-DS 14.

If Digital/PDIU-DS port 04 is the only PDIU port connected to a modem (Pro- gram 20, LED 03 ON), then the Modem LEDs on all DKTs will light.

4)From PC 2’s keyboard, type A T D D 1 0 and press ENTER (AT commands must be capi- tal letters); this prompts PDIU-DS (14) to dial and connect to PDIU-DI (10).

INSTALLATION-PERIPHERALS

SECTION 100-816-207

MARCH 1993

The CONNECT LED on the PDIU-DS (14) will be lit; the Data Call and Modem LEDs on DKT 10 will also be lit.

The screens on PC 1 and PC 2 display, CONNECT XXXX, where XXXX is the data transmission speed set by the com- munication software.

At this time, PC 1 and PC 2 are con- nected, as shown by the thick lines, to exchange data (file transfers, typed mes- sages, etc.).

5)To terminate the call: Press the telephone

Data Release button, and

a) Type + + + from PC2 keyboard.

The PC screen displays, OK.

b) Type A T H from the PC keyboard used in step 5a.

PC 1’s and PC 2’s screens both dis- play, NO CARRIER.

The DATA and MODEM LEDs on DKT 10 will turn off.

10.86PC Auto Dial Voice Call Test (see Figure

7-38)

There are many off-the-shelf, IBM/MS-DOS com- patible, desktop organizer software packages that provide an auto dialer function. One of these is the terminal resident SideKick. It is used in this section for test explanation purposes only. If you choose another auto dialer software package, the detailed response may be different than that shown here.

1) DIU Programming:

Program 20: Port 01. LEDs 01, 02, and 17 ON; all other LEDs OFF.

Program 39: Port 01. Data Call (56) and Data Release (54) buttons are optional; if the PDIU-DI is only used for the PC auto dial application, the Data Call and Data Release buttons are unnecessary.

2)Make sure that the auto dial application soft- ware is installed on the PC root directory and that the communication parameters of the PC and application software are set to the same values (in this test example, Sidekick “SKINSTAL” program).
