Installation 2-3PRISM 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.

ATA

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-

-CTS D

ELAY

Position S2-4 sets the delay on an RTS-to-CTS transition as

shown in Table 2-J.

OOP

ODE

Position S2-5 selects the loopback method as shown in

Table 2 -K.

OWNLOAD

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.
