1)Consult the serial printer’s documentation and determine if the printer operates as a DCE or DTE device:

•If the printer is a DCE device: Disas- semble the PDIU-DS and configure it to operate like a DTE device by placing the jumper plugs (P1 ~ P9) in the “B-C” (MODEM) position. Reassemble the PDIU-DS, and mark “B-C” on the bottom identification label for future reference. (Paragraph 10.70 provides PDIU-DS dis- assembly/assembly instructions, and Fig- ure 7-31 provides jumper plug informa- tion.)

•If the printer is a DTE device: It may not be necessary to disassemble the PDIU- DS, since it comes direct from the factory configured as a DCE device. However, if uncertain, disassemble the PDIU-DS and verify that jumper plugs (P1 ~ P9) are in the “A-B” (DTE) position. Reassemble the PDIU-DS and mark “A-B” on the bottom identification label for future ref- erence. (Paragraph 10.70 provides PDIU-DS disassembly/assembly instruc- tions, and Figure 7-31 provides jumper plug information.)

2)Connect the PDIU-DS to the appropriate digi- tal telephone circuit per wiring diagrams in Section100-816-208and information provided in Section 100-816-206.

3)Connect the appropriate RS-232 cable be- tween the printer and the PDIU-DS (see Fig- ure 7-27 and 7-29 for an example printer cable connection).

4)If steps 2 and 3 are done properly, the Power and Ready LEDs on the PDIU-DS should light when the printer is turned on and ready.

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

NOTE:

If using Toshiba computers and printers with X-On/X-OFF flow control, set SW1-(4) “ON” on the DIU connected to the computer and DIU connected to the printer.

IMPORTANT NOTE!

Check the printer’s serial documentation for correct RS-232 pin requirements. The requirements vary with each manufacturer.

6)Use Program 20 to configure the PDIU-DS to connect to a serial printer (see Programming Section 100-816-302for instructions and record sheets).

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

•LED 02: Should be OFF for PDIU-DS ports connected to printers.

•LED 03: Should be OFF for PDIU-DS ports that connect to DTE- or DCE-type printers.

•LED 04: Should always be ON for PDIU- DS ports.

•LED 05: Should be OFF for PDIU-DS ports connected to printers.

•LEDs 17 ~ 20: Data security groups can be used to allow or deny digital tele- phones equipped with PDIU-DIs access to PDIU-DS ports connected to a printer. DIU stations can only make data calls to DIUs in the same data security group.

7)Program 22 should be used to configure PDIU-DSs to hunt if more than one PDIU-DS connected to the same printer/server.

10.60PDIU-DS to Modem Installation

10.61STRATA DK16 enables asynchronous-type (not synchronous) modems to be connected to PDIU-DSs. This allows PDIU-DI equipped digital telephones that are connected to personal comput- ers, terminals, and other devices to share access to a modem or modem pool.
