8. If you are not using all three RLDS units you can dis able them on the Gateway see Section 11 2 RLDS Enable Screen If they are disabled on the RLDS Gateway then the corresponding addresses are free to be used by other 16AI boards RLDS I amp O Manual Note that because the Gateway reserves three 16AI Board numbers for its own use an I O Network with a Gateway is limited to thirteen 13 16AI boards Note also that since 16 is the highest board number possible a Gate way s dip switch may not be set to any number above 14 Einstein Mode In the Einstein mode the Gateway board responds as a series of three IRLDS units numbered in succession Ad dressing the boards represented by the Gateway is achieved by setting dip switches 1 through 4 to the first unit number to be used When this number is set the Gateway will also use the next two board numbers above the first board number For example if a Gateway dip switch is set to board number 4 the Gateway will use IRLDS numbers 4 5 and 6 Once the RLDS Gateway has been added to the network the Connected I O Boards and Controllers screen in E2 from the E2 Main Menu press 7 7 2 will also need to be adjusted to show the correct number of IRLDS units This number should be the total number of RLDS IRLDS IL and MRLDS up to 16 can be mapped to one IRLDS units being used on that Einstein E2 Since the RLDS Gateway can support up to three 3 RLDS units the first RLDS

The first step is to determine whether the RLDS Gate way should emulate 16AI boards known as the RE FLECS mode or if the RLDS Gateway should emulate IRLDS units in Einstein E2 known as the Einstein mode When dip switch 8 is in the ON position it selects the RE FLECS mode and when dip switch 8 is in the OFF position it selects the Einstein mode REFLECS Mode In the REFLECS mode the Gateway board responds as a series of three 16AI Analog Input boards numbered in succession Addressing the boards represented by the Gateway is achieved by setting dip switches 1 through 4 to the first board number to be used When this number is set the Gateway will also use the next two board numbers above the first board number For example if a Gateway dip switch is set to board number 3 the Gateway will use board numbers 3 4 and 5 on the I O Network Once the RLDS Gateway has been added to the net work the O Board Device Numbers screen in REFLECS from the REFLECS Home screen press 7 7 2 will also need to be adjusted to show the correct number of input boards This number should be the total number of input boards plus the number of RLDS units Since the RLDS Gateway can support up to three 3 RLDS units the first RLDS unit maps to the first RLDS Gateway address and the second RLDS unit maps to the second RLDS Gateway address therefore if the RLDS Gateway address 3 then RLDS unit 1 will appear on 16AI 3 and so forth
