2. The TTY and Modem function cannot
operate on separate RSIU/RSIS/RMDS/
RSSU/PIOU/PIOLJS ports simultaneously;
if both functions are programmed at the
same time on separate ports, the function
of the lowest numbered RSIWRSIW
RMDS port (TTY or Modem) will be active.
3. System power must be turned off/on or
Program 91-2 must be run to transfer
Program 76- 1 anytime Program 76-1 is
changed.
4. If code Y=l is set to enable the RSIU,
RSIS or RMDS to function as a TTY RS-
232 maintenance port, turn Program 77- 1,
LED 14 off. To enable the RMDS remote
modem operation, Program 77-l LED 74
must be ON.
Program 76-2(X-Z)-RSIU/RSIS/RMDS Port
Assignments
Assigns each installed RSIU port to operate at a
specified transmission rate. Where X identifies the
RSIU/RSIS/RMDS Port No.1 - 4 and Z identifies the
RSIU/RSIS/RMDS port transmission rate in bits-per-
second (bps) as shown below.
H Z=l ,960O bps
n
Z=2,4800 bps
4 Z=3,2400 bps
q Z=4,1200 bps
Note:
The sum of the transmission rates of
equipped RSIWRSISIRMDS ports cannot
exceed 9600bps. Ports assigned "no-function"
(code 0) in Program 76-2X-Y will not be
included in the transmission rate sum. The
RMDS will only function at 1200 or 2400 bps
(see Program 77- 1 LED15).
Program 77-1 -Peripheral Options
(Initialized data reads all LEDs OFF.)
n
Door Lock Time, LED 20-The Door Lock Relay
contact may be programmed to operate for either
three or six seconds (applies to PIOU, PIOUS,
PEPU, DDCB, and HDCB door lock controls).
n
Port Number/Door Phone/Lock Control Units,
LEDs 16 - 19-Door phone/lock existence is
defined by this program. Door phone/lock
controllers (DDCBs and/or HDCBs) can only exist
at Ports 004, 012, 020 and 028, and can only be
installed on Circuit 5 of a PDKU, RDSU, PEKU
and/or PESU. PDKUs and RDSUs support
DDCBs, but not HDCBs. PEKUs and PESUs can
support HDCBs, but not DDCBs. After assignment
of a DDCB or HDCB, door phone numbers (#151
- #159, #161 - #163) will effectively replace the
station number assignment in Program 04. The
door lock option is set via Program 77-2.
n
RMDS or IMDU Modem, LED 14-This program
enables the DK280 built-in maintenance modem
function: RMDS or IMDU. If the RMDS or IMDU
remote modem is used, turn "On" LED 14, if the
RMDS or IMDU is not used, turn "Off" LED 14.
Only one DK280 built-in modem RMDS or IMDU
can be used in the DK280; if both are installed,
RMDS will be accessed when a CO line direct
rings the modem or is transferred to the modem
by dialing Cnf/Tm+M9.
If LED 14 is off, the RSIU Port (l-4) which is set
for TTY operation (Code 1 in Program 76-l) will
operate as a local RS-232 maintenance port. If
RSIU is not configured as TTY, then the
PIOU/PIOUS/RSSU that has code 41 set in
Program 03, will operate as a local TTY
maintenance port.
Other system Programs that are related to the
system modem are: Program 76, RMDSJTTY
assignments on RSIU PCB; Program 78-51-53,
system CO line to modem ringing assignments;
Program 71-1, DNIS line to modem ringing
assignments: Program *09, DID line to modem
ringing assignments: Program 77-1, LED 15,
RMDS modem Protocol/speed assignments.
W RMDS Protocol, LED 15-This program sets the
RMDS communications standard type to
CCIlTN.22bis (2400bps) or Bell 212A (1200bps).
The standard set in this program must match the
standard of the modem that will be used to
communicate with the DK280 RMDS.
If the RMDS modem standard should be
2400bps/CCITT/ V.22bis, turn LED 15 on; if the
RMDS standard is a 1200 bps/Bell 212A, turn LED
15 off. Most Hayes compatible modems will
function with either standard; check with the
modem manufacturer's documentation to verify
which protocol should be used. When the system
is initialized the Bell 212A (1200 bps) standard is
set (LED 15 off).
