Peripherals Specifications

Introduction

This appendix provides details on the IGX peripherals specifications.

Note EIA/TIA-232 and EIA/TIA-449 existed as recommended standards RS-232 and RS-449 before the Electronics Industries Association (EIA) and Telecommunications Industry Association (TIA) accepted them as standards.

Network Management Terminal

StrataView Terminal

A Cisco WAN Manager workstation is required for managing an IGX network. Refer to the Cisco WAN Manager Installation publication for setup instructions and specifications for the Cisco Network Management Terminal. The Cisco WAN Manager Installation publication has all the necessary information for obtaining network alarm, control, and statistics from IGX switch software for Cisco WAN Manager.

Control Terminal

Table B-1 lists the control terminals requirements.

The High Speed Serial Interface DIP Switch consists of two DIP switches, SW1 and SW2, located on a serial-board that is attached to the printer's main board. Set switches 1 and 2 as indicated in Table B-4 and Table B-5.

Table B-4: Switch 1 Settings—Okidata 184 Printer

Switch 1	Setting	Description

2	On
3	On
4	On	DSR active.
5	On	Buffer = 32 bytes.
6	On	Timing = 200 ms.
7	On	Space after power on.
8	Don't care	Not used.

Modems

In general, a dial-out connection to a modem uses the AUX port on the SCM. A dial-in connection from a modem uses the Control port on the SCM. Refer to Table B-6 for interface requirements.

Table B-6: Modem Interface Requirements

Parameter	Requirement
IGX port used:	Control port on SCM is used for auto-answer modem. AUX port on SCM is used for auto-dial modem.
Code:	Standard 8-bit ASCII, 1 stop-bit, no parity.
Interface:	EIA/TIA-232 DCE.
Cable:	Null modem cable.
Phone lines:	Dedicated, dial-up business telephone line for TAC-to-IGX modem and auto-dial-to-TAC modem.
Data rate:	Standard, asynchronous rates 3.0-19.2 Kbps, independently software-selectable.
Supported modems:	Motorola Model V.34R 9600 baud modem.

Motorola V.34R IGX Dial-In/Out Configuration

IGX Auto-Answer

Auto-answer is a setup in which the TAC can dial into the your switch. Using the cnfterm command, set the IGX Control port speed to 9600 bps. Using the cnftermfunc command, set the terminal type to VT100/StrataView. To program the modem, temporarily attach a terminal to the modem using a null modem cable. The modem EIA port automatically match the 9600 bps setting of the terminal. Enter the commands listed in Table B-7 to set up the modem for proper operation.

Table B-7: Setting Up the Motorola V.34R Modem for Auto-Answer mode

Step	Command	Function
1.	AT&F&W	Reset to factory default and save.
2.	ATSØ=1	Enables Auto-Answer Mode (answer on first ring).
3.	ATL1	Modem speaker at low volume.
4.	AT*SM3	Enables automatic MNP error correction.
5	AT*DC0	Disables data compression.
6.	AT*FL0	Disables XON/XOFF flow control.
7.	AT&S1	Sets DSR to "normal".
8.	ATEØ	Disables local character echo.
9.	ATQ1	Disables result codes. (Modem will appear "dead").
10.	AT&W	Saves current configuration settings in non-volatile memory.

IGX Auto-Dial

Using the cnfterm command, set the IGX Auxiliary port (AUX port) speed to 9600 bps and enable XON/XOFF flow control. Using the cnftermfunc command, select option 7, Autodial Modem, then enter the Cisco-designated Network ID and the Cisco modem phone number. Attach a 9600 bps terminal to the modem using a cross-over cable and enter the following commands (Table B-8).

Table B-8: Setting Up the Motorola V.34R Modem for Auto-Dial mode

Step	Command	Function
1.	AT&F	Initializes factory defaults.
2.	ATL1	Modem speaker at minimum volume.
3.	AT*SM3	Enables automatic MNP error correction.
4	AT*DC0	Disables data compression.
5.	AT*SC1	Enables DTE speed conversion.
6.	AT*FL1	Enables XON/XOFF flow control.
7.	AT*SI1	Enables 5-minute inactivity disconnect.
8.	AT&C1	DCD controlled by modem.
9.	AT&D2	Modem disconnects when node toggles DTR.
10.	AT&V	Verifies entries.
11.	AT&W	Saves current settings to non-volatile memory.

Connect the modem to the IGX AUX port using the cable shown in Figure B-1. Ask the Cisco TAC to assist in the modem testing.

Modem Cables

The IGX Auto-Dial to Cisco application (also called "call home") and IGX Auto-Answer (call from Cisco) application use different modem cables. Figure B-1 shows the modem cable pinout for IGX Auto-Dial to Cisco's TAC. Figure B-2 shows the modem cable pinout for IGX Auto-Answer (call from Cisco TAC).
