BPX Peripherals Specifications
This appendix provide details on the specifications for peripherals used with the BPX.
A StrataView Plus workstation is recommended for managing a BPX network. Refer to the StrataView Plus Operation Manual and StrataView Plus Installation Manual for setup instructions and specifications for the StrataCom Network Management Terminal, one of which is required to provide network alarm, control, and statistics monitoring for IPX, IGX, and BPX nodes.
The control terminal connected to the CONTROL port can be used on BPX nodes for local configuration and monitoring as long as there is at least one StrataView Plus workstation attached to a node in the network. Local control is especially useful during installation, initial power-up, and configuration. See Table A-1 for configuration data.
Table A-1 : Control Port Parameters for StrataView Plus
| Parameter | Setting |
|---|---|
| BPX Port Used: | Serial CONTROL port, located on the LM-BCC card, is used for the local control terminal. |
| Code: | Standard 7 or 8-bit ASCII; 1 or 2 stop-bits; even, odd or no parity. |
| Interface: | RS-232 DCE. |
| Data Rate: | All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable. |
| Supported Terminals: | Any terminal compatible with DEC VT-100. |
| Cable Required: | Straight-through RS-232 cable. |
The standard maintenance printer that is currently being shipped with the BPX is the Okidata Model 184 dot matrix printer. This printer may be connected to any node. Refer toTable A-2 and Table A-3 for printer configuration requirements. Note that this is not the same as the printer that may be provided with the StrataView Plus NMS terminal but in addition to it.
Table A-2 : Auxiliary Port Parameters for OkiData 184 Printer
| Parameter | Setting |
|---|---|
| BPX Port Used: | Serial AUXILIARY port, located on the LM-BCC card, is used for the maintenance printer. |
| Code: | Standard 8-bit ASCII; 8 data bits, 1 stop-bit, odd parity. |
| Interface: | RS-232 DCE. |
| Data Rate: | 9600 baud. |
| Supported Printer: | Okidata 184. |
| Cable Required: | Straight-through RS-232 cable |
DIP Switch Settings for Okidata 184
DIP Switch A is an 8-section DIP switch located on the printer's main circuit board. Access to the configuration switches is made by sliding back the switch cover at the top, rear of the printer case. Set Switch A as indicated in Table A-3.
Table A-3 : Switch A Settings---Okidata 184 Printer
| Switch A | Setting | Description |

| 1 | Off | ASCII with |
| 2 | Off | non-slashed |
| 3 | Off | zero. |
| 4 | Off | 11-inch |
| 5 | On | paper. |
| 6 | Off | No Auto Line Feed. |
| 7 | On | 8- bit data. |
| 8 | Off | Enables front panel. |
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 A-4 and Table A-5.

Table A-5 : Switch 2 Settings---Okidata 184 Printer
| Switch 2 | Setting | Description |
|---|---|---|
| 1 | Off | Transmission |
| 2 | On | Speed = 9600 baud. |
| 3 | On | Speed = 9600 baud. |
| 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. |
StrataCom ISC uses modems for diagnosing and correcting customer problems with installed BPX systems. The modem that is currently recommended for use with the BPX is the Codex Model V.34R.
In general, a dial-out connection to a modem uses the AUX port of the BPX. A dial-in connection from a modem uses the CONTROL port of the BPX. Refer to Table A-6 for interface requirements.
Table A-6 : Modem Interface Requirements
| Parameter | Requirement |
|---|---|
| BPX Port Used: | CONTROL port on SCC card is used for auto-answer modem.
AUX PORT on SCC card is used for auto-dial modem. |
| Code: | Standard 8-bit ASCII, 1 stop-bit, no parity. |
| Interface: | RS-232 DCE. |
| Cable: | Null modem cable. |
| Phone Lines: | Dedicated, dial-up business telephone line for ISC-to-BPX modem and auto-dial-to-ISC modem. |
| Data Rate: | All standard asynchronous data rates from 300 to 19200 bps, independently software-selectable. |
| Supported Modems: | Motorola V.34R modem. |
Motorola V.34R BPX Dial-In Configuration
This is a setup for StrataCom ISC to dial up the customer's BPX. Using the cnfterm command, set the BPX 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 will automatically match the 9600 bps setting of the terminal. Enter the commands listed in Table A-7 to set up the modem for proper operation.
Connect the modem to the BPX CONTROL PORT. Ask StrataCom ISC to assist in testing the operation of the modem setup
Table A-7 : Setting Up the Motorola 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). |
