Installing the Enwatch 11
Flash Memory
If it is necessary to change the firmware, the flash memory is located in
position U20 and U28 (see Figure 1.2 on page 4). This flash memory is socket
mounted to allow you to change the EPROM. Make sure that the orientation
of the chip is correct when installing.
On Board Monitor When you insert a jumper into JP21, the Enwatch unit operates in its internal
monitor mode. This enables you to change the IP address as well as modify
other options. To invoke monitor mode, connect a terminal (or PC computer
in terminal mode) to the serial port and insert a jumper at position JP21.
Remove the power and then reconnect the power to reset the unit. A sign-on
message appears on the terminal together with a list of options (described in
“Setting Up an Enwatch Unit”, below).
To exit monitor mode, simply remove the jumper at position JP21, then
remove and reconnect the power to reset the unit.
Setting Up an Enwatch Unit Before installation, make sure you have plant specific IP network addresses
available for each Enwatch unit. For convenience write them down here.
IP Address 1: ____________________ IP Address 6: ____________________
IP Address 2: ____________________ IP Address 7: ____________________
IP Address 3: ____________________ IP Address 8: ____________________
IP Address 4: ____________________ IP Address 9: ____________________
IP Address 5: ____________________ IP Address 10: ___________________
You should also know the Subnet Mask and Gateway IP address (if available)
for each Enwatch unit.
1. Attach the Enwatch unit to the test computer via the RS-232 (serial)
port using a null modem cable.
2. Make sure the jumper in the middle of the Enwatch unit board is
inserted (JP21).
3. Start up any terminal program (Winterm, QVT/Term, Procomm,
etc.…) and set it up to communicate through the serial port at 9600
Baud, No parity, 8 data bits, and 1 stop bit.
