As with any electronic device, you should take care while handling to avoid damage from static 
electricity. Before removing the 

UCERB 24 from its packaging, ground yourself using a wrist strap or 

by simply touching the computer chassis or other grounded object to eliminate any stored static charge. 

If your 

UCERB 24 is damaged, notify CyberResearch, Inc. immediately by phone, fax, or e-mail.

The 

UCERB 24 has two on-board switches that you set to configure the relay logic polarity and the 

resistor pull-up/down configuration. Configure these switches before you connect the external power 
supply to the 

UCERB 24. Factory-configured default settings are listed in Table 2-1. Refer to Figure 3.1

 

for the location of each switch on the
