Operation
IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller
03/12 34
RS-232 Input or PC Control
The RS-232 input feature allows a computer to send information, which will cause the desk set to initiate
a 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 <CR> (carriage return) must be sent to the desk set. If the desk set is not currently busy and
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.
Paging
Paging allows the PC to direct the desk set to transmit a paging sequence using a preprogrammed alias or
a specified cap code. The behavior of each specific page type is controlled by the CARD Suite
programmed parameters.
Byte Value Description
0 2
‘2’ (0x32): Always for Paging
1
0 or 1
‘0’ (0x30): Indicates an alias number is used
‘1’ (0x31): Indicates a capcode is used
2 Page
Type
‘1’ (0x31):
DTMF
‘2’ (0x32):
2-Tone
‘3’ (0x33):
Plectron
‘4’ (0x34):
5/6 Tone
‘5’ (0x35):
2805
‘6’ (0x36):
1500
Y1
First ASCII digit of capcode or alias number (Most significant digit)
4
Y2
Second ASCII digit of capcode or alias number
5
Y3
Third ASCII digit of capcode or alias number
6
Y4
Fourth ASCII digit of capcode
7
Y5
Fifth ASCII digit of capcode
8
Y6
Sixth ASCII digit of capcode (Least significant digit)

Example:
To send a 2-Tone page using capcode 123 and the CARD Suite programmed settings for 2-Tone paging:
PC to IPE2500A:
‘^’, <CR>
IPE2500A to PC:
‘0’, ‘1’, ‘8’ (Response)
PC to IPE2500A:
‘2’, ‘1’, ‘2’, ‘1’, ‘2’, ‘3’, ‘~’ (Page transmitted)
IPE2500A to PC:
‘~’ (Acknowledgment to PC that page is complete)
Alias paging works similarly to DTMF signaling with the alias number being as listed in the CARD Suite
software for page aliases.
