APPENDIX A REMOTE PROGRAMMING
Remote programming capability has been incorporated in the NX-SERIES via the R-MMC
serial port on the SMDR/R-MMC board option mounted on the base unit. This port is
configured as a programming port only. The remote programming capability of the NX-
SERIES can be used to add, delete, or modify a customer database. While remote
programming gives added flexibility to the NX-SERIES, it is not possible to UP/DOWN load
from or to a disk or tape. All NX-SERIES MMCs may be accessed via remote programming.
1. SITE REQUIREMENTS
1.1 CUSTOMER SITE REQUIREMENTS
Before using remote programming, the following requirements must be met at
the customer site:
Install the optional NX-SMDR/R-MMC board in the base unit.
MMC 80 Change Baud Rate: This MMC will set the baud rate of communication
R-MMC port to match the customer site's modem. Baud rate selections are 300,
600, 1200, 2400, 4800, and 9600. 8 Data bits, No parity, 1 stop bit is default.
MMC 80 Assign Remote Port: When remote programming is used,it must
reference an installed N X 2 4 E keyset at the customer site. This keyset will be
disabled for the duration of the remote programming session. When remote
programming is not in use, this assigned keyset will function normally. The keyset
port selection should be made considering minimal inconvenience to site
personnel during programming sessions.
NOTE: There are no physical connections between the keyset and modem or
keyset and communication port. The assigned keyset is used as a software
reference point only.
A customer-provided modem and cable connected to R-MMC comm port, as
shown below:
A voice grade dial-up line on which the modem may be called.
1.2 REMOTE SITE REQUIREMENTS
Personal computer (PC) with communication software that can emulate
VT-102 terminal.
NOTE: Since communication software can vary, no assurance can be made
that every communications software package will work properly.
Internal or external modem able to match baud rate speed with the modem at
the customer site
Voice grade dial line to call customer modem.
