Receive Data Mode (SW18-7)
Setting switch SW18-7 to ON sets the 3040/V35 (CTS MD-V.35/TCB) into the Gated Mode. Only the Sub-Channel that is currently active will receive the data from the master port. Setting position 7 to OFF enables the Broadcast mode. Receive Data from the Master Port is sent to all Sub-Channels.
Control Turn-Off Delay in “DATA” Switching Mode (SW15-3,4)
When configured to switch on DATA, switch SW15-3 and 4 set the Sub-Channel release time in clocks. The value selected is the number of clocks at the current baud rate that must occur without any data transitions on the Sub-Channel to indicate that Sub-Channel has completed its transmission and the 3040/V35 (CTS MD-V.35/TCB) can resume servicing the other Sub- Channels. The following table should be used to set this time period.
SW15-3 SW15-4 CLOCKS
ON | ON | 16 |

ON | OFF | 64 |

Switch on Data / Control (SW17-5,6,7,8)
Each sub-channel is independently selectable for switch on data or switch on an active interface control lead. Set SW17 pos 5 to OFF if sub-channel 1 switch on Data is required. Set pos 5 to ON if switch on interface control lead is desired. Position 6 thru 8 are associated with sub-channels 2 thru 4.
Internal Baud Rates (SW15-5,6,7,8)
Switch SW15-5, 6, 7 and 8 select the master clock rate when Internal Clock Source is selected on TX Clock Source or RX Clock Source. In addition the Fallback clock rate is also selected with this option. When Fallback clocking is required, the RX Clock Source and TX Clock Source should not be set to INTERNAL. SW15-5, 6, 7 and 8 selects the clock rate of the Fallback Clock when Internal Clock Fallback is selected. The following table shows the available rates.
