By selecting the proper impedance for each drop, there may be up to 50 receivers in one application. Each of the DIP switches on the Model 2085RC function card is a S1-1 Setting 4-position switch. -
Page 5: Switch Setting - Modem A
The setting for switch S1-4 determines whether the Model 2085RC echoes data back to the transmitting device (half-duplex mode only). Switches S2-3 and S2-4 are set together to determine whether the Model 2085RC is in 2-wire or 4-wire operating mode. Note: 2-wire S1-4 Setting mode is half-duplex only. - Page 6 S4-3* 2-Wire/4-Wire 2-Wire 4-Wire The setting for switch S3-2 determines the amount of delay between the time the Model 2085RC “sees” RTS and when it sends S4-4* 2-Wire 4-Wire 2-Wire/4-Wire CTS.
