CAUTION – Equipment damage. The RS-485-to-RS-232 converter cables have 1 or 2 batteries (9 Vdc) which
supply power to the boards during direct connection. No additional voltage source is required during direct
connection for configuration.
Do not use two batteries to supply power to boards with part number 2104836-001. The boards will be damaged
when the supplied power is greater than 15 Vdc (2 fully charged 9 Vdc batteries can supply up to 18 Vdc).
To prevent battery drain when converter cables are not in use, make sure the red wire is removed from the
positive terminal contact on the battery holder.
