Lot No: 20Z9 Manufactured on December 20th, 1999
The year is indicated with the last digit. In this case, "9" indicates "1999."
Month of manufacture. October, November, and December are indicated
with X, Y, and Z respectively. In this case, the month is "December."
Day of manufacture. In this example, the day is "20."
NT31/631(C)-V2 are the only PTs for which high-speed NT link is supported.
Except for the baud rate, the 1:N NT Link communications specifications are
fixed. Therefore, the port settings, start bits, stop bits, and parity need not be
set. Even if they are set, they are ignored.
Set the serial communications mode to 2 Hex to use 1:N NT Link mode.
With 1:N NT Links, up to eight Programmable Terminals (PTs) can be con-
nected. The highest connected unit number is set here.
This section describes the bits and words used by the Serial Communications
Board and Serial Communications Units in the Auxiliary Area and the Status
Area allocated in the CIO Area. The Software Switches allocated in the CIO
Area are not used for 1:N NT Links.
