Monitor to pins labeled 15V 15V 5V and Ground Interface Connections General There are many potential sources of interference when testing ballasts particularly ballasts of the HID type This interference can severely affect interface cabling of poor quality or with insufficient shielding Particularly in a high volume production environment it is highly recommended that all cable lengths be kept to a minimum and that the highest quality fully shielded cables be used IEEEA88 Interface A standard IEEE488 interface cable the use of a high quality fully shielded cable is highly recommended should be attached to the IEEE488 connector on the rear panel of the 2574R RJ45 Style 1500 Chassis Interface If configured to control one or more 1500 chassis using this interface using the 1510 controller interface in the 1500 chassis then these should be connected to the RJ45 style LOAD connectors on the 2574R rear panel Other than the order in which redundant load and switches are selected there is no particular importance to which connector s are used Redundant loads and switches are selected first from the lowest numbered load connector and the lowest lettered slot in that chassis 92 2574 User s Guide When connecting or disconnecting a 1500 chassis the 2574R may take up to 5 seconds to recognize the change A straight through 8 wire RJ45 cable should be used For cable routing longer than 10 feet the use
