Operations Manual, HPA3, Mini Compact Outdoor SSPA 208143 REV - 55

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.
