1.3 FUNCTIONAL DESCRIPTION
ELTERM 24 Operator Interface Terminal
The ELTERM 24 is a simple operator interface "dumb" terminal designed to
operate with an intelligent control. The Terminal has two primary functions;
display data/messages sent from the control on its screen and transmit key-
presses to the control via its keypad.
All display maintenance is provided by the control. This includes displaying
characters, erasing characters, and cursor positioning. The ELTERM 24 does
not echo keypresses to its display. Therefore the control must transmit all
characters received from the ELTERM 24 back to the terminal for display.
The ELTERM 24 also has a key repeat feature which can not be disengaged.
When a key is pressed, the character is transmitted, then after a delay of about
0.5 seconds, if the key is still depressed, the same character is re-transmitted
at a speed of 10 per second.
Power Supply
The ELTERM 24 Operator Interface requires a 12-24VDC 300mA power
source. The recommended power supply is Part Number 227928-001 which is
a 24VDC 300mA switching supply. Wiring connections and dimensions are
given in Section 3, additional specifications are provided in Section 4.
