A Serial 1-Wire
that LOG08-II is now discontinued. This information is provided for reference only.
This is the second generation of 1-Wire
logging devices (LOG08 was the first) and this project builds on the success of it's
predecessor, TEMP08. LOG08-II retains many of the previous features of the
TEMP08, and adds some extras.
Features of the LOG08-II include;
Standard RS232 serial interface between the
Dallas/Maxim 1-Wire bus and a host PC
provides real-time relief for the host PC
by removing the burden of providing the precision timing required by the 1-Wire bus
No connection to PC required for
Polling display and logging support for the following 1-Wire
DS18S20, DS18S20-PAR, DS1822, DS18B20 and DS1920
DS2438 based Sensors
DS2423 based counters
DS2450 based voltage sensors
Easy option programming (Set and Forget)
- NO option jumpers required.
Capability to interface up to 60
different sensors and log up to 24 of them
Optional on-board DS2438 or DS18S20 temperature sensor
Optional on-board humidity sensor
Connectivity to 1-Wire bus via either
terminal strip or RJ-12 connector
capability for sensor logging
Discrete commands for
setting all important parameters
Battery backed up Real Time Clock for
displaying time of day with results of sensor polls or logs
PCB Size fits into
optional PacTec CM5-125 case
EASY software upgrades
via recyclable processor changes
Here is what LOG08-II looks like (may not
be exactly as shown):
J1 Power Input connection. 12 to 16
Volts AC or DC required
J2 Serial Interface connector.
Standard DB-9 female connection.
J3 1-Wire and external interface. +5V, GND and
J4 RJ-12 interface for 1-Wire
bus. +12V, +5V, GND and DQ provided.
