10 RS232 Interface Telemetry / Gateway Comms
Overview
The iRIS may be used to communicate via external telemetry devices such as data radios or modems using
its RS232 port. When an external RS232 communication device is connected, the iRIS is also capable of doing
“store and forward” or “gateway” communications. This feature allows data packets that are not addressed
to this logger to be redirected to other HyQuest Solutions devices. This chapter describes using the RS232
Telemetry function and also explains the gateway communications functionality.
RS232 Port Telemetry
If the RS232 port is to be used for telemetry, then its normal terminal/binary mode at 38400bps is disabled
and the port becomes fixed to iQuest binary protocol at the user configured port speed. There are two
methods of enabling the RS232 telemetry mode.
RS232 Only Telemetry Mode
If the iRIS does not have an internal wireless modem or else the internal modem is unused, the iRIS can be
configured for “RS232 Only” telemetry mode. This mode is controlled by the iRIS software based on various
actions (see table below) and the RS232 port does not need a special cable for connection to external
communications devices.
In RS232 Only telemetry mode, any call-back messages will always be directed out the RS232 port.
This is why telemetry mode is enabled when a user is logged in. It allows call-back testing to be
done using the LCD/keypad.
Switching between telemetry and “normal” modes is controlled by the following actions:
Action
Mode
Key pressed when user is not logged in
Normal
User is logged in
Telemetry
User has just logged out
Normal
RS232 port activity in terminal or data download modes
Kept in Normal
At least 2 minutes of no activity on keypad or RS232 port
