Verilink PRISM 4001 (34-00244) Product Manual - Manual (Page 13)

Installation 2-3 PRISM 4001
If in Standard mode, set the DTE Rate as shown in Table 2-F.
Configuration Switch S2
Switch S2 (Figure 2-3) is used to set the configuration
parameters listed in the following paragraphs.
DTE M ODE
Position S2-1 sets the unit to one of two general modes:
Sync or Async (Async is allowed only in the TxPORT-pro-
prietary mode) as shown in Table 2-G.
D ATA M ODE
Position S2-2 sets the communication link to proprietary
mode (TxPORT equipment must be located on both ends) or
to industry-standard mode (it interoperates with standard
equipment from another vendor) as shown in Table 2 -H.
RTS C ONTROL
Position S2-3 sets the behavior of the RTS and CTS as
shown in Table 2-I.
RTS- TO -CTS D ELAY
Position S2-4 sets the delay on an RTS-to-CTS transition as
shown in Table 2-J.
L OOP M ODE
Position S2-5 selects the loopback method as shown in
Table 2-K.
D OWNLOAD ON R ESET
Position S2-6 is used in conjunction with the front panel
FAR/LOC switch to force the 4001 into a software down-
load mode as shown in as shown in Table 2-L. The FAR/
LOC switch controls the download baud rate as shown in
Table 2-M. If S2-6 is in the Up position at power up, the
4001 enters download mode at the rates specified by the
FAR/LOC switch.
