Operations Manual, HPA2, Compact Outdoor SSPA 205486 REV F 103
11.0 Remote Operation
The Paradise Datacom Compact Outdoor SSPA utilizes Terminal Mode Serial Protocol
(TMSP) as a secondary serial protocol for Management and Control through a Remote Serial
Interface. TMSP allows the user to access internal SSPA functions via a remote ASCII
Terminal or its equivalent (such as HyperTerminal for Windows). TMSP is accomplished
through either the RS-232 or RS-485, half duplex, serial communication link.
U.S. ASCII encoded character strings are used to represent commands and data messages.
A remote terminal or controller initiates a communication session and the SSPA takes action
and returns a report of requested status. The SSPA will not initiate communication and will
transmit data only when commanded to do so. Prior to establishing a session with a SSPA,
this mode must be enabled through the front panel menu.
The remote terminal must be configured with serial settings that match the SSPA’s serial port
settings. For example, if the SSPA is set at 9600 Baud, the remote terminal must be also
configured as ASCII terminal at 9600 Baud, no parity, 8 bit data with 1 stop bit serial connec-
tion. The SSPA will not echo back any incoming characters, so local echo must be enabled
on the remote terminal.
To establish a remote control session with the SSPA terminal, the user must type UNIT#XXX
in the terminal window, where XXX is the SSPA unique network address or the global call ad-
dress (255). Press “Enter” on the Remote Terminal keyboard.
The Compact Outdoor should answer with Unit#XXX OnLine and display the first menu
screen on the following lines. After a remote session is successfully established, the unit will
remain connected as long as needed.
The session is organized in as menu selection with active keys. To help the user navigate
through the menu, a help string with the list of active keys always follows the menu strings.
For example:
“Active Keys(U)p+Enter; (D)own+Enter;(C)learFlt; (M)enu+Enter; (E)nd+Enter”
will be the last transmission string on all informative menu screens.
Note: All letters must be in upper case!
To refresh the screen on the remote terminal, simply press the “Enter” key. To end a session
with the Compact Outdoor SSPA, press the “E” and then “Enter” keys.
Important! If multiple SSPA units are networked on the same serial link, do not estab-
lish a session with more than one SSPA at a time. If you do so, you will not get a valid
response from the SSPA.
