When reassembling please note that the top and bottom are keyed to fit in only one direction. Electrical Interface Selection Each of the two ports on the SeaPORT+2 can be individually configured as an RS-232, RS-422, or RS-485 interface. This is selectable via the DIP switches and DIP shunts. Each of the switch positions is described on the following page. - Page 8 No effect ON : Adds a 1 K ohm pull-down resistor to RX- 422 and 485 option. OFF: No effect ON : Adds a 120 ohm termination resistor between RX+ and RX- © Sealevel Systems, Inc. 2203 Manual | SL9098 9/2022...
