The 53A-311 FET Scanner Slave Card is designed to be used with the 53A-310 FET Scanner Card to form a single scanner system with the capability to multiplex up to 256 differential analog input channels. Each FET Slave Card provides an additional 32 differential input channels to the 310/311 scanner system without any degradation or loss in system performance specifications.
Up to seven 53A-311’s may be controlled by a single 53A-310. The base address for each Slave Card is set by three rocker switches. Once the base address has been set, the 53A-311 requires no direct programming. All of its commands are received directly from the 53A-310 using a dedicated 8-bit data bus. Addresses o n the data bus are decoded, along with the base address select switches. to determine which of the Slave card’s 32 differential analog input channels to connect to the 53A-310 Card common analog output.
