IMl66-107
Data Device Connections
The system provides two RS232 Data Ports for use.
0
When you use a video display terminal (VDT) to
perform class of service programming, connect it to
RS232 Data Port A.
0
When you use a serial data printer for SMDR,
SMDA, and COS printout, connect it to the RS232
Data Port B.
0
When you use a Caller ID Interface (product code
CID08) to identify incoming calls, connect it to
RS232 Data Port B using the special cable provided
with the CID08. Refer to the paragraph titled
C&r
Identification Service Support (located on page
4-40) for installation details associated with this
feature.
The distance between a data device and the common
equipment can be up to 500 feet in a quiet electrical
environment. Some sites may require shielded cable
for long runs. For longer distances, you must install
limited distance modems to relay the data
communications between the common equipment and
a data device.
When preparing a cable for connection to a data
device, refer to the manufacturer’s manual for the
equipment being interfaced and make the following
wiring connections:
0
Wire the common equipment RD (data from device
to common equipment) connection to the device TD
(transmit data) connection.
0
Wire the common equipment TD (data to device
from common equipment) connection to the device
RD (receive data) connection.
0
Wire the common equipment SG (signal ground)
connection to the device SG (signal ground)
connection.
0
If required for proper operation, wire the common
equipment CTS (clear-to-send status from device to
common equipment) connection to the device RTS
(request-to-send) connection.
NOTE: The common equipment requires a positive
voltage, with respect to signal ground, in order
to send data.
The default data communications format is as follows:
0
7-bit data with 2 stop bits and no parity
0
Baud rate of 300 baud
Configure a data device to match Jhis format for initial
operation or reprogram the system’s data format to
match those of a data device.
The system’s data ports are located as follows and are
connected as illustrated in
