Upgrading Monitor
Firmware using the IR
Connect Software
This section describes upgrading the Monitor’s firmware using the IR Connect
Software.
Upgrade may be product improvements to add additional features or to enhance
monitor performance. Most firmware upgrades are not required unless notified by us.
To determine if your monitor has the most current revision, please contact us.
1 Position the monitor in front of the IR Connect. Perform a READ DEVICE prior to
performing any upgrades to ensure a connection has been established.
2 After a successful READ DEVICE has been acknowledged, click on the Folder
icon located in the bottom right of the screen. Then select the firmware file
(Pro_ZM_vX.X.img format) to upgrade to and then click UPGRADE
FIRMWARE. This takes about 30 seconds to perform. See Figure 37.
Do not move the monitor during the firmware upgrade. Also, note the location of the
file.
(If applicable) If the monitor has been exposed to gas exceeding the low
alarm set point, a value appears with MAX next to it. This represents the
peak value (highest) that the monitor has seen. After this screen, another
appears displaying a value with (hours, days, or months), this represents
the amount of time past since the peak reading.
(If applicable) After the peak reading and time since screens, another
screen displays with CLP (Clear Last Peak).
If you press the button while this is displayed, the peak value on the
monitor resets.
Note: The value is cleared from the display, but the value is stored in the
monitor’s event log. This value may be cleared on the next screen.
