EIA Interface Leads (Signals)
Both DIUs operate with 10 standard EIA RS-232 interface leads (signals) on which signaling data 
is transmitted and received. RPCIs and DIUs connect to serial data devices with standard RS-232 
cables, available from telephone supply stores (see Figures 10-24~10-29 and 10-31). The RPCI-
DI/PDIU-DI/PDIU-DS requires 10 signals for some applications, but can function with eight using...

Clear to Send (CTS, Pin 5)
The DCE device sends the CTS signal (EIA circuit CB) which indicates that it is prepared to 
transmit data to the line side. The DCE device sends this signal only when it receives the RTS 
signal from the DTE device. Sometimes, the DTE/DCE device may use RTS/CTS for Ready/Busy 
type flow control; in these cases, DIP switch SW1-4 should be OFF.

Notes
lNever use modular cords and adapters when connecting a RPCI-DI/PDIU-DI/PDIU-DS to a modem.
lConnection examples 1 and 2 work when using the RPCI-DI or PDIU-DI to make calls with personal computer applications 
(auto-dialers, printer sharing, outgoing modem calls, etc). If the PC RPCI-DI or PDIU-DI must receive calls, the RI...

lMode select (P1~P9) “A-B” if PDIU-DS is connected to a terminal-type device (DTE).
lMode select (P1~P9) “B-C” if PDIU-DS is connected to a modem-type device (DCE).
lDo not cut the Perception strap when installing a PDIU-DS in Strata DK Systems.
