Toshiba DK8, DK 16 manual Important Note

NOTE:

The PDIU-DI always operates as a DCE de- vice; therefore, unlike the PDIU-DS, it has no internal jumpers.

3)Connect the appropriate RS-232 cable be- tween the PDIU-DI’s DB-25 female connector and the PC’s appropriate asynchronous serial communications port connector (COM port).

IMPORTANT NOTE!

Check the PC manufacturer’s serial com- munication port interface documentation for correct RS-232 pin requirements; re- quirements vary with each manufacturer. The number of EIA RS-232 signals required (8, 9, or 10 wires) depends on the applica- tion. When EIA signal requirements are not known, connect the 10 EIA signals listed in Paragraph 10.20. Figures 7-25 and 7-30 provide diagrams for connecting RS-232 cables between PDIU-DIs and Toshiba lap top, and IBM, XT and AT PCs.

4)Set the PDIU-DI DIP switch (SW1-1~ 4) for the desired application. Figure 7-32 shows the DIP switch locations and Paragraph 10.30 describes switch functions.

5)Access Program 20 to configure the PDIU-DI for DTE-type connection and Program 39 for data button assignments of the digital tele- phone connected to the PDIU-DI.

Program 20

•The port number entered for the PDIU-DI in Program 20 is the port number of the digital telephone to which the PDIU-DI is connected.

•LED 01: Should always be ON for PDIU- DI ports.

•LED 02: Should be ON for PDIU-DI ports, unless the PC user will never use DIU AT commands (other than ATDD, ATDT, and ATD) and never require the PDIU-DI to send result codes to display on the PC display screen. Frequently, it is difficult

to determine the full extent of these requirements; so it is recommended to turn LED 02 ON. See the Data Interface User Guide for information regarding DIU AT commands and result codes.

•LEDs 03 and 04: Should be OFF for PDIU-DI ports.

•LED 05: Should be ON if the system is installed behind a PBX or Centrex that uses access codes to make external calls or to insert a pause following DIU access of an outside line.

•LEDs 17 ~ 20: Used to establish data security groups. PDIU stations are only allowed to make calls to PDIUs in the

same data group to which they are as- signed.

Program 39

•The following data call buttons can be assigned digital telephones equipped with PDIU-DIs: Data Call, and Modem. Assign SD buttons to data devices as required. Do not assign DSS buttons to data devices; DSS buttons are used for voice calls only.

10.50PDIU-DS to Printer Installation

10.51STRATA DK8 and DK16 enables serial print- ers (laser, dot matrix, or other types) to be con- nected to stand-alone data interface units (PDIU- DSs). Digital telephones equipped with PDIU-DIs 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.

NOTES:

1.Only serial printers (not parallel) that con- form to EIA RS-232 signaling require- ments can be connected to PDIU-DSs.

2.In rare applications, it may be desired to connect printers to PDIU-DIs. Refer to the printer’s installation instructions.
