Wiring an asynchronous serial link
The shielded serial link cable with the reference HG2829A is used to connect asynchronous data
terminals to the CA1 card in V24/V10 mode.
The following tables give a list of the circuits in the V24 junction on the CA1 card.
Connecting a DCE (CA1) to a DTE (PC or VT100 console)
Note: Circuit 107 “Data set ready” (PDP or DSR) is not present on the CA1 card. The straps
are not shown in this table.
Connecting a DTE (CA1) to a DCE (modem or V24 adapter)
Note: Circuit 107 “Data set ready” (PDP or DSR) is not present on the CA1 card. The straps
are not shown in this table.
