EX1 Port Expander
(actual size 7.0 x 2.50 inches)
The Arcom EX1 Port Expander allows you to connect up to 3 additional full-duplex/half-duplex/simplex radios to the RC210 while using only 1 Port on the RC210 itself. Each additional Port is enabled/disabled by the Logic Outputs (UF) of the RC210 and may be used individually or simultaneously.
Additionally, the EX1 may be used to link more than one RC210, effectively providing more Ports to be used any way you need.
Polarity of each transceiver’s COS signal is easily selectable by push-on jumpers on the pc board and audio levels (both RX and TX) are adjustable as well.
