DUET
This is the Date and Time format where, MM= Month, DD= Date, YY= Year, WD= Weekday,
HH= Hours MM= Minutes, SS= Seconds (24 hour clock), DS= Daylight Savings= Y, N.
SERIAL PORT
The DUET has one serial port setting that must be properly configured in order to communicate with a
communications port or modem. If a modem is used press the up key to edit the modem initialization string.
The PC (personal computer) serial port communicates with a computer or modem and is used
for data communications including scheduling and verification logs. It consists of a pair of RJ-
11 / RS-232 plugs located on the rear panel of the DUET labeled THRU/COMM IN. The right
port (facing the rear) is the "IN" plug and has an arrow pointing up. The left port (facing the rear)
is the "THRU" plug and has an arrow pointing down. The "IN" plug connects to a computer or
modem.
The "THRU" plug is provided so that multiple (unlimited) DUET's can daisy chain off a single
host computer or modem. When multiple DUET units are daisy chained together, the "THRU"
connection of the upstream unit connects to the "IN" connection of the downstream unit. No
termination is required on the last DUET in the chain.
The PC (COMM IN) on the DUET and the host PC (personal computer) must have matching
BAUD, DATA BITS, STOP BITS and PARITY settings to ensure proper communications.
The format of the serial port settings is
BBBBB = Baud
300 – 1,036,800 baud (bits per second)
D = Data Bits
S = Stop Bits
P = Parity
Note:
When the select key is pressed to edit the PC serial port, the cursor defaults to the baud field. To
edit other fields use the left or right key to enter the field.
Note: If more than one DUET is connected to a PC or modem (via a daisy chain connection), all the Duet's
must have identical PC SERIAL PORT settings.
