25. ng for propagation delays While the falling edge of the ST signal from the DCE is ideally located mid bit of the SD signal coming into the DCE it is not necessary for it to be mid bit In fact it s usually not mid bit due to delays This is often misunderstood The actual requirement is that the set up time for the register that the SD signal is being loaded into be met and this is usually a fraction of the available bit time The only time there is a problem is when the falling edge of the ST is too close to the SD transitions at the DCE interface and this prevents the set up time from being met If the ST falling edge is far enough away from the SD transition edges when the new SD data bit has met the set up time the DCE will still clock the data reliably even though it isn t mid bit This is why many ST timing set ups will work with no regeneration required at all When the edges are too close at the DCE the FOM will need to retime the data on the opposite edge of the ST signal by setting switch 1 8 to ON This will allow that when the propagation delays are taken into account the edges have skewed enough to meet the set up time at the DCE Note that in installations where the data rate may be changed or the cable lengths may change due to patch panel routing of equipment it s entirely possible that a combination of switch settings that works in one scenario will not work in another The only solution to these situations is to insert more de

28. s The drivers and receivers for V 11 signals are compatible with the MIL STD balanced specifications and the V 10 interface is similar to MIL STD unbalanced MIL STD 100 signals use the same negative MARK condition as TIA circuits so there is no need to invert the TD and RD signals MIL STD 188 114A is set up for user control of the MARK level so the need for data inversion at the FOM will need to be made on a case by case basis If the MIL STD interface uses any unbalanced signals such as MIL STD 188C note that this standard uses a positive MARK then provisions will need to be made to externally bias one side of the receivers on the FOM to use them single ended Note that the MIL standards are only an electrical specification and do not specify a pin out or connector type so a custom cable will be required in many cases Asynchronous Isochronous or Synchronous operation The FOM is transparent to data and clocking formats so there are no switch settings for distinguishing the different modes of operation When a pair of FOM 1090 units is used as modem link between two DTEs all of the input signals are transferred to the crossed over corresponding outputs i e TT from the DTE is provided as RT out of the FOM 1090 at the opposite end When the FOM is used in Send Timing applications certain switch options may be used to eliminate clocking issues that may arise Those options are explained below Send Data Regeneration when using Send Timin
