Line 1 shows an outbound or desk set-initiated PTT ID. Line 5 shows an outbound Call Alert. Line 6
shows the inbound acknowledgment for the Call Alert on line 5.
Lines 7 through 12 show an outbound Call Alert that did not receive an acknowledgment. Line 12 shows
that the Call Alert failed. If during the retry sequence, the operator terminated the Call Alert, the status
would show ABORT.
If an alias of “SHERIFF” is programmed for the unit ID 1234, the printout contains the alias name instead
of the actual unit ID as seen below.

RS-232 Input or PC Control
The RS-232 input feature allows a computer to send information, which causes the desk set to initiate a
MDC1200 message, page (without talk time), frequency change or custom tone transmission.
In order for the desk set to expect data from the RS-232 port and lock-out the desk set keyboard, a “^”
(caret) and a
in normal operation, it returns the ASCII string “018”. At this point, control of the desk set from the front
panel is not possible; however, it is recommended that the keyboard not be used during a PC direction of
the unit. After the PC has received the “018”, data may be sent to the desk set.
The functions of PC Control are described below. Note that all bytes are represented in ASCII format.
