Configure line interface between LP200 and the attached CU200
For AE200 see special instructions.
Measure the line attenuation at 1000 Hz and 3000 Hz in each direction of the line.
In LP200 the amplification (at 1000 Hz) and equalization (additional amplification at 3000 Hz) is adjusted
by straps, as well as proper connection for 4-wire or 2-wire line.
In CU200 the selection of 4-wire or 2-wire line is done by straps.
In CU210 the selection of 4-wire or 2-wire line is done via personality programming of Area 1 TAB 30.
In each CU connected to the LP, following coding has to be done in the local EEPROM (Area 1):
•
A unique ID-digit 1 - 6 has to be dedicated for each CU200, see specifications "CU ID NUMBER" in
MRS3000 PROGRAMMERS REFERENCE MANUAL
.
If you have a CU210 used as interface to the public telephone network or a local telephone
exchange, it shall be given the ID number 0.
•
Line amplification and equalization; see specification "LINE LEVEL" in
MRS3000 PROGRAMMERS
REFERENCE MANUAL.
Software in the LP200/210 has to be informed if the connection is 4-wire or 2-wire.
Programming of Area 2 TAB 02 does this.
Configure radio interface
The used radio-type shall be specified, see specification "RADIO" in
MRS3000 PROGRAMMERS REFERENCE MANUAL.
The frequency divider constant given to the radio for each channel shall be specified in 2 tables, RX and
TX separately. See specification "RADIO RX" and "RADIO TX" in
MRS3000 PROGRAMMERS
REFERENCE MANUAL.
For each channel, the following specifications must be given:
- If it exists
- If it is tone-scanned
- If simplex/duplex radio channel
- If repeater traffic allowed
- If open traffic is allowed
- Signalling system options
- If automatic select table for tone transmission
- If squelch controlled repeater when isolated base
- If 2-tone or 5-tone repeater start
See "CHANNEL INFO" in
MRS3000 PROGRAMMERS REFERENCE MANUAL
for further specification.
Max. 15 channels (= radio frequencies) could be used.
If less than 15 frequencies are used, different channel numbers could select the same frequency at the
radio, but with different options. For example you could select either of the signalling systems A and C
by specifying different channel numbers.
