Serial Interface Operation 5–4 MN-LPOD
5.2.7 End-of-Life Commands/Queries
Certain commands/queries are marked by CEFD as End-of-Life (EOL). Noted with an asterisk (*) in the Parameter Type column (full
details are available in Section 5.4), these commands are fully supported in this product, although CEFD strongly recommends that you
use the equivalent new commands for new implementations:
EOL-designated Command/Query
New Command/Query / Comment
Functionality not included in any other remote command/query
PNM. New query provides more exact unit hardware information.
Functionality not included in any other remote command/query.
5.3 Remote Control Protocol and Structure
The electrical interface is either an EIA-232 connection (for the control of a single device) or an EIA-485 multi-drop bus (for the control of many
devices). Data is transmitted in asynchronous serial form using ASCII characters. Control and status information is transmitted in packets of
variable length in accordance with the structure and protocol defined in this chapter.
5.3.1 EIA-232
This is a simple configuration in which the Controller device is connected directly to the Target via a two-wire-plus-ground connection.
Controller-to-Target data is carried, via EIA-232 electrical levels, on one conductor, and Target-to-Controller data is carried in the other
direction on the other conductor.
