7.5 Terminal Mode Serial Protocol for Paradise Datacom SSPA
The Teledyne Paradise Datacom Rack Mount 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. US ASCII
encoded character strings are used to represent commands and data massages.
A remote terminal or controller initiates a communication session and the SSPA
Terminal takes action and returns a report of requested status. The SSPA terminal will
not initiate communication and will transmit data only when commanded to do so. Prior
to establishing the session with the SSPA Terminal, this mode must be enabled
through the SSPA 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 connection. 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 (all letters must be in upper case), where XXX is the RM SSPA
unique network address or the global call address (255). Press the "Enter" key on Re-
mote Terminal keyboard.
The SSPA should answer with words "Unit#XXX OnLine" with the first menu screen on
the following lines. After a remote session is successfully established, the unit will stay
connected as long as needed. The session interface mimics the SSPA's front panel
menu. To help the user navigate through the menu, the help string with the list of
active keys always follows the menu strings. For example:
"Active Keys:(U)p+Enter;(D)own+Enter;(C)lrearFlt; (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 current screen on the Remote Terminal simply press "Enter" key. To end a
session with RM SSPA, press "E" and then "Enter" keys.
