2. On-site Programming Via PC Terminal
On-site programming via a PC terminal has been incorporated into the NX-828H via the
communication (serial) R-MMC port on the optional SMDR/R-MMC card mounted in the base unit.
This port is fixed as a programming port only. The on-site programming capability of the NX-828H
can be used to add, delete or modify a customer database. While on-site programming gives
added flexibility to the NX-828H, it is not possible to upload to or download from a disk or tape.
ALL NX-828H MMCs may be accessed via on-site programming.
2.1 On-site Requirements
Before on-site programming can be used:
¡Ü
Install the optional SMDR/R-MMC card in the base unit.
¡Ü
Use a customer-provided PC terminal with communications software that can emulate a VT 103
type terminal.
NOTE
: Since communications software can vary, no assurance can be made that every
communications software package available will work.
¡Ü
Use MMC 80 to set the baud rate, Data bit, Parity bit, and Stop bit of the R-MMC port of the
optional SMDR/R-MMC card to match the customer's PC terminal. Baud rate speed selections
are 300, 600, 1200, 2400, 4800 and 9600. 8 bit / 7 bit data, No parity / Even parity / Odd
parity, and 1 stop / 2 stop bit are selectable.
¡Ü
Use MMC 80, Remote Station option: When on-site programming is used, it must reference an
installed NX24 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
assigned keyset will function as a normal keyset. No default data has been set and a keyset
port selection should be made that will offer the minimal inconvenience at the job site.
NOTE
: There are no physical connections to be made between the assigned keyset and the
communications 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.
¡Ü
A customer-provided cable must be connected between the PC terminal and the R-MMC port.
2.2 Begin Programming
Once communications have been established, press the TAB key on the PC keyboard and you will
receive the NX-828H header display (shown below). If you receive a "SORRY DESTINATION
PORT IS BUSY" display, the keyset assigned in MMC 80 is currently busy and no on-site
