2. ON-SITE PROGRAMMING VIA PC TERMINAL

On-site programming via a PC terminal has been incorporated in the NX-SERIES via
serial communication port R-MMC of the SMDR/R-MMC board mounted on the Base
board. This port is configured as a programming port only. The on-site programming
capability of the NX-SERIES can be used to add, delete, or modify the customer
database.  While on-site 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 on-site programming.

2.1 ON-SITE REQUIREMENTS

Before on-site programming can be used, the following requirements must be
fulfilled:

●

An installed optional SMDR/R-MMC board in the base unit.

●

A customer-provided PC terminal with communication software that an

emulate a VT-103 type terminal. 

NOTE: Since communication software can vary no assurance can be made that

every communications software package available will work.

●

MMC 80 Change Baud Rate: This MMC sets the baud rate, data bits, parity

bit, and stop bit parameters of the R-MMC port on the SMDR/R-MMC board 

to match the customer's PC terminal. Baud rate speed selections are 300,
600, 1200, 2400, 4800 and 9600. 8 data bits, 7 data bits, No parity, Even
parity, Odd parity, 1 stop bit, and 2 stop bits are selectable.

●

MMC 80 Assign Remote Port: When on-site programming is used, it must

reference an installed NX 24 keyset at the customer site. This assigned keyset 
will be disabled for the duration of the on-site programming session. When 
on-site programming is not in use, this keyset will function normally. A keyset
port selection should be made that will offer minimal inconvenience to
personnel site. 

NOTE: There are no physical connections between the assigned keyset and 

the communication port. The assigned keyset is used as a software
reference point only. If the assigned keyset is a display keyset, it will
echo the programming keystrokes from the PC terminal.

●

A customer-provided cable must be connected between the PC terminal

and COM R-MMC port.

2.2 BEGIN PROGRAMMING
