PRL-1600 SYSTEM DESIGN AND
PLANNING
Revision: 4/10/22
SYSTEM CONFIGURATION - The PRL-1600 can be used in one of two configurations: 4 Form A pulse
channels or 2 Form C pulse channels. The entire system operates in either one mode or the other. They cannot
be mixed.
Form A Configuration: The Form A configuration will transmit four 2-Wire (KY) pulse channels.
Form C Configuration: The Form C configuration will transmit two 3-wire (KYZ) pulse channels.
Determine the desired mode for the system.
Dip Switch DS1's switches #1 through #3 set the channel # or "hop" sequence. Both the PRT Transmitter and
the PRR Receiver units must be set to the same channel or hop sequence. See Table 1 at left.

SYSTEM CHANNEL - The PRL-1600 System operates on one of 6 hop sequence channels. Each channel
consists of 50 unique frequencies out of 64 frequencies available in the 902MHz to 927MHz range. This allows
great reliability since RF transmissions are transmitted on one of the channel frequencies until they are received
by the receiver. Set the Transmitter and the Receiver to the same channel number. Multiple PRL-1600 systems
can operate in the same radio airspace by each system having a different channel number. Once you have
determined the channel # that you will use, configure Dip Switch S1's switches #1 through #3 on the PRT-16 or
16S Transmitter Base board and the PRT-16 Receiver Base board. Table 1 shows the dip switch combinations
for each channel.

SYSTEM OPERATING MODE - The PRL-1600 System operates in a near real-time operational mode, where
the PRT-1600 Transmitter transmits one transmission every 10 seconds with the pulse data it has received from
the meter over the previous 10-second period. When the transmission is received by the PRR-1600 Receiver,
pulses are generated over the next 10-second period. Additional error checking and pulse verification are used
in this mode for the highest possible accuracy. Packet Transmissions and Receptions are visually indicated
with an LED on both base units.

#7 are specific to the
Transmitter or
Receiver.
