14.6 SSBM Setup Configuration
Connect the modem to the SSBM by connecting one end of the serial cable to the
UPS Port 2 DB---25F connector and the other to the modem (refer to Chapter 13,
“Serial Communications”). If using a standard serial cable, a null modem adapter
is required for the connection to the modem.
The Powerware 9315 SSBM can only use serial Port 2, DB---25F, for the Remote
Notification option. This connection is located on the Customer interface Panel at
the top right of the SSBM cabinet.
The remote modem operates at only 2400 baud.
Following the instructions in Chapter 9, “Using the Control Panel” and Chapter 13,
“Serial Communications”, use the LCD screen and pushbuttons on the Monitor
Panel to access the setup screen and configure Port 2 as follows.
NOTE: The modem should be connected to the SSBM as described in the modem
manufacturer’s manual before configuring the SSBM communications port.
<MODE> Remote Notify
<RATE> The baud rate at which the modem will communicate
to other modems, 2400 baud.
<DATA/STOP> 8 1 Standard 8 data bits, 1 stop bit, no parity.
<HANDSHAKING> Disabled
<SAVE> Yes. To save new configuration.
The handshaking feature listed is for SSBM-to-terminal handshaking, not
SSBM-to-modem handshaking. Setting the handshaking to “modem” has no
effect. If the remote terminal has buffering problems because of excessive data
transfer rate from the SSBM, XON/XOFF handshaking can be selected to resolve
this issue. The user must make sure that the modem (not the remote terminal) at
the remote terminal end of the connection is configured for either hardware
handshaking or none at all. This is required so that the modem does not attempt
to trap the XON/XOFF characters and prevent them from being transmitted to the
SSBM.
