Obtaining the Required Components
To install an RDAC with Octel’s proprietary modem for use with the Octel Overture 350,
you need the following components:
-
Dedicated telephone line
-
110-Vac (230 Vac in Europe) power receptacle
-
HP 700/43 or Wyse 55ES terminal (for RDAC SMT)
-
Octel’s proprietary modem, P/N 010–3600–000, or any V.23 compatible modem,
such as the Bocamodem (P/N 003–1424–000)
-
RS-232C male-to-male DB-25 cable
-
267A adapter
Optionally, you can attach a standard touch-tone telephone and a printer to the RDAC.
Installing the RDAC
To install the RDAC, do the following:
1. From the Octel Overture 350 location, connect the dedicated telephone line to pins 1
(ring) and 26 (tip) to the J25 connector on the main distribution board of the Octel
Overture 350. Pin 1, the ring side of the tip and ring, has a blue/white wire. Pin 26,
the tip side, has a white/blue wire. Use a hooded, 50-pin, male Amphenol-type
connector to connect the telephone line. Figure 5-1 shows the location of the J25
connector.
2. From the RDAC location, connect one end of the DB25 cable to the RS-232C
connector on the modem.
If you want to be able to access the Octel Overture 350 from the RDAC without a
telephone, you need a cable that does not have pins 6 or 8 on the RS-232 connector.
This type of cable allows the autodial characters to be displayed on the RDAC SMT.
3. Connect the other end of the cable to the port labeled DATACOMM on the HP
700/43 terminal or to the port labeled MODEM on the Wyse 55ES terminal.
4. Attach the 267A adapter to the RJ-11 connector on the telephone.
5. Connect a standard telephone cord from the 267A adapter to the connector labeled
PSTN on the modem.
