3.5 DIGITAL COMMUNICATIONS
A second digit number 2 thru 6 in the part number indicates that the controller has been specified and manufactured with a
Digital Communications option.
To enable Digital Communications, push the YES key at this display. See
OPERATOR Flow Chart in Section 7.2.
To disable Digital Communications, push the NO key to this display.
The host cannot enable digital communications. This can only be accomplished by a key press on the front keypad of
the controller. Even after communications is enabled, local control is still allowable.
During host-controlled operation, the front keypad remains active so that you can override the host and can take
control if necessary.
The REM indicator light will flash when the communications is enabled. The REM indicator light will continue to flash
until communications is disabled via the keypad. The host can also turn the REM indicator full on as part of the
STATUS INPUT (PSW) command to inform you that the host is in control. Also included in the host command
structure is manual control of the controller output(s).
