Hey Ken, Per the ebay listing web picture...
The Arcom RC-210 repeater controller now sports (has) RJ-45 (the larger telephone type used in computer networks) type jacks on the pc board along with what appears to be the silk screen locations for the original D-9 (aka db-9) jacks/plugs. When you have time would you please comment on the change? ... reason and thinking behind the option/change? Can the db-9 jack/connector locations still be used? thanks skipp
