Environment:
Hyper Terminal

Cause:
To troubleshoot internal ION Modems, complete the following procedure then analyze the different strings.

Resolution:
Make two connections to the meter: COM1 via RS232/485 and the modem via RJ11

  1. Switch COM1 protocol to Modemgate
  2. Open a HyperTerminal session to COM1
  3. To see the typed text and responses, select File > Properties > ASCII Setup > and check the 'Echo typed characters locally' box > click OK

  4. Log the entire connection (Transfer> Capture Text)
  5. Power cycle the meter. In HyperTerminal there will be some init strings with some OK responses, wait until it is done
  6. Type ati0 (to get the modem type)
  7. Type at&v (to get the current settings)
  8. Dial into the meter via modem. In HyperTerminal you should see RING, then hear a bunch of squawking (the modem establishing a connection) if there is a speaker. At this stage do not press any keys; it will list the negotiation parameters.
  9. Disconnect the site. You should see a disconnect message in HyperTerminal
  10. Ensure the LED lights on the side of the meter go out. If they don't type ath0
