Option 5
This option allows you to configure the RS232 port parameters. This menu is a chained input which means it
prompts for multiple entries one after the other before returning to the communication menu.
These settings only apply when the iRIS has its Power Save mode set to “RS232 Only” and it
is actually in Telemetry mode. Otherwise the RS232 port operates normally at 38400bps.
The first RS232 port setting field is the speed in bits per second.
> RS232 Speed (0:1200,1:2400,2:4800,3:9600,4:19200,5:38400bps)=
The second parameter is the address of the base station to use when calling back using the RS232
telemetry mode. The base address is normally set to zero.
> Base Address=
If the unit will be expected to call back to HydroTel via a gateway site elsewhere, the base
address will need to be set to a suitable value (normally the gateway setting in the gateway
logger). If the base address is left set to zero, call-back will fail.
Finally, the third entry field is for the RS232 gateway offset. Use 0 to disable gateway communication. If this
is not zero, then a gateway block of 100 locations is set up starting from the offset. E.g. If the gateway offset
was set to 3000 then any address between 3000 and 3099 inclusive would be retransmitted back out the
RS232 port with aliasing applied.
> Gateway Offset=
The RS232 Only gateway mode is different to the wireless IP to RS232 bridge mode that
requires a special cable to invoke. See Section 2.3.10 and RS232 Interface Telemetry for more
detail on using gateway communication.
Option 6
Select this option to enter the Phone List menu. This menu enables the entering of up to two phone numbers
to use as destinations for either SMS text messages or CSD dial-up call-back.
Option 7
This option prompts you to enter a number representing the call-back mode for the wireless modem. This is
the mode to use when the iRIS notifies an alarm notification or a test call is initiated from the keypad.
> Mode (0:IP, 1:CSD, 2:SMS)=
Option 8
By using this terminal mode, it is possible to perform two distinct functions depending on the state of the
internal modem. If the terminal is available, this message is displayed.
> Terminal Mode active. Press <ESC> and then <Enter> to exit.
If the internal modem is powered down then terminal mode is unavailable and this message will appear.
> Wireless module inactive. Terminal unavailable.
Assuming the modem is active, the two scenarios are as follows:
 If the internal modem is powered up, but an IP or CSD session is not in progress, then it is possible
to interact with the modem using the standard AT command set.
 If the internal modem is powered up and an IP or CSD session is currently in progress, then it is
possible to interact with a terminal at the remote end of the connection.
