7.3.3 SSPA unit powers up, LED lamp glows green, but no RF output signal is present

Possible causes: The SSPA is muted by an external signal or by an internal setting. The
input RF signal is too low. The input signal is out of band.

Possible solutions: Make sure the J4 connector has a jumper installed between pins B and
V (refer to Table 3-1 or Table 3-2). Connect to the unit via the Universal M&C and set the
Mute setting to Off. Check the input RF signal level and frequency. Make sure the signal
properties are appropriate for the unit.

7.3.4 Cannot connect to SSPA through remote control interface

Possible causes: The SSPA remote control is set to a different interface setting. The
interface cable is not wired properly or has a broken wire harness. A PC interface port
malfunction. An incorrect version of the software is being used to control the unit. The
selected SSPA protocol is no longer supported by the SSPA firmware. In the case of RS232
interface: the wire harness is using the Chassis ground rather then a Com ground pin. In case
of IPNet or SNMP interface: PC ARP cache entry is set for different MAC/IP address pair.

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 3.3.2). After establishing a
communication link with the unit, adjust the following settings to the desired configuration:
Serial Network address, Protocol Select, Baud rate (if Normal protocol was set in in the
Protocol configuration), 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. In order to use the Quick Start cable from previous generations of
Compact Outdoor SSPAs (PN L202151), the cable harness will need to be modified. To
do so, open the MS connector shell and connect the chassis and communication ground
pins together (Pins V and d).

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 Figure 3-7 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.
