Ramac / GPR Control Unit II & MULTI-CHANNEL Add-on

Control Unit II (CU II)

The RAMAC/GPR Control Unit II (CU II) connects to any of the standard RAMAC/GPR antennas without any mechanical modifications. It supports parallel ECP communication ensuring high transfer rate of data. The CU II becomes a Multi-Channel system by adding an optional module (MC4 or MC16 - see below).

Multi-Channel Add-on to CU II

The RAMAC/GPR Multi Channel Unit (MC4 & MC16) is an optional add-on module to the Control Unit II (CU II). The Multi Channel module comes in two versions, MC-4 with up to 4 recording channels or the MC-16 with up to 16 recording channels (The MC-16 connects 4 receivers and 4 transmitters). The multi channel unit has the capability to operate any of the optional receiver inputs to any transmitter (controlled through software). The repetition rate of the control unit is shared among the defined channels, i.e. the effective repetition rate equals 100kHz (standard) over the numbers of channels defined.
