Serial Pass-Through Mode

NOTE Serial pass-through functionality is available only with the ConnectUPS Card

firmware v3.20 and higher (with older, non-RoHS hardware) and v4.20 and higher (with RoHS

hardware). Updates to the ConnectUPS Card firmware are available at

http://powerquality.eaton.com/Support/Software-Drivers/default.asp.

During normal operation, the ConnectUPS Card controls the

communication path to the UPS and allows network-based access to

UPS data through the Web and SNMP. Some situations require direct

serial communication to the UPS in a pass-through mode, such as:

S The UPS firmware requires a field upgrade with a 9600 baud serial

port connection to the UPS.

S The user wants to run a local copy of LanSafe software with serial

communication to the UPS.

The card's Normal mode of operation must be disabled for Serial

Pass-Through mode to be available.

Reconfiguring the Card for Serial Pass-Through Mode

NOTE In Serial Pass-Through mode, communication through the ConnectUPS Card Ethernet

port stops, and any existing connections (such as to NetWatch software clients or SNMP

management tools) cease. However, the Ethernet switch functionality of the ConnectUPS

Card continues to function.

The following steps disable Normal mode by changing the switches on

the ConnectUPS Card and restarting the card in Serial Pass-Through

mode.

To reconfigure the card for Serial Pass-Through mode:

1. Note the current position of DIP switches on the card [the default

setting for both switches is the 0 (off) position]. Write them here for

later reference.

DIP Switch 1 _____ 0 (off) _____ 1 (on)

DIP Switch 2 _____ 0 (off) _____ 1 (on)

2. Set both DIP switches to the 1 (on) position for Serial Pass-Through

mode.
