Portable Digital Pressure Gauge
CPG2300 Series
Battery Charging: The CPG2300 has a built-in battery charger that will take approxi-
mately 8 hours with an input supply of 12VDC to fully recharge a battery. The built-in
charger will switch from fast charge to maintenance mode automatically when a full
charge is achieved. It is acceptable to leave the wall transformer connected to AC
power indefinitely.
Charge Voltage vs. Temperature: The battery can be charged over an ambient
temperature range of 0 to 40 degrees C with a supply voltage of 9 to 12 VDC.
3.5 Serial In/Out Communications
The serial port is configured as RS-232, 9600 baud, 8 data bits, 1 stop bit and no parity.
It is designed as a 9-pin DCE device, so that a straight pin to pin cable can be used to
connect it to a standard PC serial port. The serial port can be used to configure and
calibrate the CPG2300 or to read the output of its sensors.
Wiring requirements are provided in the Installation section and a list of valid commands
and responses (Table 7.2.3) is provided in the Remote Operation section.
