P0 is display during POST - When the POST is complete, P1 appears and the RAN is ready for the following programming steps. - Press the LEFT ARROW to enter programming mode. The current NODE NUMBER (1n, 2n,3n or 4n) is displayed - Press the RIGHT ARROW repeatedly until the desired NODE NUMBER is displayed. - Press the left arrow to select the node number entered in the previous step. Pn will appear momentarily, meaning that the node has been successfully programmed. The display then return to P1 and awaits microcode download from the controller. - AC indicate that IPL is complete and RAN is ready. En error in RAN If En appears, the RAN has been improperly programmed in one of the following way. - The RANs have not been programmed in ascending order. That is, the RAN displaying the En has been programmed to a lower number than the preceeding RAN. - Two or more RAN have been programmed assigned the same number. The RAN displaying the En has been programmed to the same number as another node on the same controller line. NOTE: Node number should be assigned in ascending order on each controller line. The RAN closest to the controller being 1n, the second RAN 2n and so on. Numbers greater than 4 will not configured.

Neither the 128-port adapter or the RAN supply any handshake signals (CTS, RTS, DTR, DSR) to the DSU/CSU or modem. These cables may need to be customized based on the individual modems used. Often the DSU/CSU or modem needs to have Forced RTS or Forced DTR set. Digital Sync Modem (CSU/DSU) It is a requirement that in Digital circuits that the TxC be derived from the Network. The speed of the line, the modems and the SMIT setting for the adapter line should all be set to the same value. If the line is a 56 KB Both DSU/CSU (Local and Remote) need to be set to derive their clock signals from the line. This may require an EXTERNAL clock setting or a slave clock setting. Analog Sync Modems The first modem has the MASTER TxC CLOCK. This means that it is usually set to INTERNAL clocking. It is recommended that the HOST modem be the MASTER clock modem. The second modem is the SLAVE to the Clocking. This means that it is usually set to EXTERNAL clocking and sometimes to SLAVE clocking as well. Some modems use the term TRIBUTARY clocking.
