Possible solutions
:
a) In the case where SSPA communication settings have been accidentally set to a random
configuration, establish a connection to the unit with a L207755 Quick Start cable in
conjunction with the Universal M&C software (see
Section 3.2.2.2
). After establishing a
communication link with the unit, adjust the following settings to the desired configuration:
Serial Network address, Communication Interface, Baud rate (if Serial was set in in the
Communication Interface), IP address, Subnet, Gateway, IP port and IP lock address (if
IPNet or SNMP protocols were selected), Community Set and Community Get strings (if
SNMP protocol was selected), web password (if IPNet was selected).
Disconnect the Quick start cable, and cycle AC power to the unit with the custom cable
harness plugged into the J4 M&C connector. Recheck custom control link.
b) In the case of a RS232 interface, make sure to use communication ground pin
d
from the
J4 connector as the RS232 ground. The SSPA RS232 port is electrically isolated from
chassis ground.
c) In the case of IPNet, use 10Base-T approved cables (CAT5, CAT6) to make a connection
to the unit. Maximum cable length should not exceed 300 ft. Use
Table 2-2
as a wiring
guideline. If an IP connection with custom IP addressing is desired, don’t make any
connection to interface selection pins j and e.
d) In the case of SNMP interface, make sure that the SNMP community strings match
between the SNMP NMS software and the unit. Default values for these strings are: Public
and Private. Connect to the unit via the Universal M&C to check or change string values.
e) In the case of IPNet or SNMP protocols, clear the PC ARP cache by issuing the following
command in a Windows command line interface:
arp –d
.
f) Binary and Terminal protocols are no longer supported by Compact Outdoor units. Use
the currently available interfaces instead.
6.3.5 The FSK link between a modem and the SSPB unit is not working
Possible cause
: The unit is set to use a different address.
Possible solution
: Set the SSPB address to 1. Reset AC power.
