Allows Ethernet connection to a PC running Statesman Indigo 1AE 1U frame with active front panel for up to six Crystal Vision modules. Allows Ethernet connection to a PC running Statesman Indigo 1SE 1U frame with passive front panel fitted with Statesman CPU for up to six Crystal Vision modules. Allows Ethernet connection to a PC running Statesman Indigo 1-DP 1U frame with power supply redundancy and passive front panel for up to six Crystal Vision modules. Includes two fixed PS-80i power supplies Indigo 1AE-DP 1U frame with power supply redundancy and active front panel for up to six Crystal Vision modules. Includes two fixed PS-80i power supplies. Allows Ethernet connection to a PC running Statesman Indigo 1SE-DP 1U frame with power supply redundancy and passive front panel fitted with Statesman CPU for up to six Crystal Vision modules. Includes two fixed PS-80i power supplies. Allows Ethernet connection to a PC running Statesman Indigo DT Desk top box with passive front panel for up to two Crystal Vision modules. Includes fixed power supply Indigo DTSE Desk top box with passive front panel fitted with Statesman CPU for up to two Crystal Vision modules. Includes fixed power supply. Allows Ethernet connection to a PC running Statesman PSU-160i 160 Watts power supply for 1U, 2U and 4U frames. 1U frames require one PSU-160i (no redundancy). 2U frames require either one PSU-160i (no redundancy) or two PSU-160i if power supply redundancy is required. 4U frames require minimum of two PSU-160i (with compulsory redundancy) or four PSU-160i if the power consumption in the frame exceeds 150W You need a rear module to access your inputs and outputs... RM01 Single slot frame rear module. Allows maximum number of DADA208 in frame (24 in 4U, 12 in 2U, six in 1U, two in desk top box). Two 75 ohm AES (BNC) inputs and two 75 ohm AES (BNC) outputs of each channel RM02 Four slot frame rear module. One rear module used for three DADA208, allowing 18 DADA208 in 4U and nine in 2U. Two 75 ohm AES (BNC) inputs and three 75 ohm AES (BNC) outputs of the first channel and four of the second RM03 Single slot frame rear module. Allows maximum number of DADA208 in frame (24 in 4U, 12 in 2U, six in 1U, two in desk top box). Two 110 ohm AES (D-Type) inputs and four 110 ohm AES (D-Type) outputs of each channel RM12 Single slot frame rear module. Allows maximum number of DADA208 in frame (24 in 4U, 12 in 2U, six in 1U, two in desk top box). Used for impedance conversion. Two 75 ohm AES (BNC) inputs and four 110 ohm AES (D-Type) outputs of each channel RM13 Two slot frame rear module. Allows 12 DADA208 in 4U, six in 2U, three in 1U and one in desk top box. Used for impedance conversion. Two 110 ohm AES (D-Type) inputs and three 75 ohm AES (BNC) outputs of each channel RM16 Two slot frame rear module. Allows 12 DADA208 in 4U, six in 2U, three in 1U and one in desk top box. Two 75 ohm AES (BNC) inputs and four 75 ohm AES (BNC) outputs of each channel with an AES (BNC) loop-through of the first RM21 Single slot frame rear module. Allows maximum number of DADA208 in frame (24 in 4U, 12 in 2U, six in 1U, two in desk top box). Used for impedance conversion. Two 110 ohm AES (D-Type) inputs and two 75 ohm AES (BNC) outputs of each channel RM35 Single slot frame rear module with 'easywire' DIN 41612 connector. Allows maximum number of DADA208 in frame (24 in 4U, 12 in 2U, six in 1U, two in desk top box). Two 110 ohm AES (D-Type) inputs and four 110 ohm AES (D-Type) outputs of each channel The DADA208 is controlled by board edges switches - therefore you will not require a control panel or PC software.
