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-SERIESMMCs 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 24keyset 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

Once communications has been established, press TAB on the PC keyboard to
receive the N X - S E R I E S header display (below). A "SORRY DESTINATION
PORT IS BUSY" display indicates that the keyset assigned in MMC 80 i s
currently busy, and no on-site programming can be done at this time. When the
NX-SERIES header is displayd, enter MMC 20 and the necessary passcode to
