COM320 Voice Communications Modem
The datalogger’s voice code is created along with the measurement program
using the CRBasic editor. It is recommended to finish and debug the voice
portion of the program first, and then add the measurement code.
The example CR1000 voice callback/callin program that follows supports the
following functions:
• Voice callin
• Voice callback
• Auto-disconnect
• Auto redial
• Alarm reset
The following steps show how to build a station to demo the example voice
callback/callin program. The voice station can further serve to test/debug a
custom voice program and merge it with an application program.
Step 1 – LoggerNet Setup
1) In LoggerNet Setup create the following device map
2) Configure ComPort and PhoneBase for your PC’s phone modem.
3) Configure PhoneRemote to include the COM320’s analog phone number
followed by six commas and a 9.
4) Click on CR1000phone (renamed) and verify that the PakBus Address is 1.
Step 2 – Hardware Setup
1) Start with a CR1000 having factory settings. If unsure of settings, close
LoggerNet, connect SC12 cable from PC ComPort to CR1000 RS-232
port, run Device Configuration Utility, set Serial Port to match the PC
ComPort, Connect and click on the Factory Defaults button, Apply
settings and Disconnect.
2) Turn off PS100 if it isn’t already.
3) Connect CR1000 to PS100 (turned off).
4) Connect SC12 cable from COM320 to CR1000 CS I/O port.
5) Connect analog phone line to COM320.
6) Turn on PS100.
7) Connect prepared TC to CR1000’s DIFF 7 analog input.
8) Connect LED with 1000 Ohm resistor connected to anode lead from C1 to
G (resister to C1).
