Partyline: MS-704, RM-704, SB-704 Internal IFB J10 Jumper settings
IFB ModeThe MS-704 and RM-704 support two different modes of operation for the internally generated IFB function. J10 on the main PC board (in the lower left hand corner of the board just behind the DIP switches) selects this mode. If an interrupt enable DIP switch is enabled for a channel, the operation will be as follows: • LOCAL (Talk Function Activated): Jumper between Pins #1 and #2, factory default. When a talk is active on the channel on which the interrupt has been enabled, the program will be interrupted for the duration of the talk from only this local panel. Other panels talking on the same channel will not interupt the program. • REMOTE (Call Signal Activated): Jumper between pins #2 and #3. When a call is received on the channel on which the interrupt has been enabled, the program will be interrupted for the duration of the call signal on that channel. To cause an interrupt of the program from this station a call signal must be sent by pressing the call button or enabling the auto-call DIP switch option for that channel and activating a talk on that channel.
Channel "A" is the only channel that can't be interrupted.
Product Affected:
- MS-704
- RM-704
- SB-704
J10 is a 3 pin header with two positions: remote & local
- Jumper between Pins 1 & 2 = local
- Jumper between Pins 2 & 3 = remote
With J10 in local position, program feed dip switches and program interrupt dip switches in "on"position:
- this tells the logic circuit(s) the interrupt the program signal when any one of the talk buttons on the front panel is activated.
Channel "A" is the only channel that can't be interrupted.
