Chapter 7 - DIP-Switch Settings

Switch #6

Slave Clocking

(Synchronous Mode/Leased Line/Dial-Up)

In Synchronous mode, DIP-Switch #6 controls the option of having timing controlled by the receive clock. The originate modem, in effect, adjusts to the answer (remote) modem. Place DIP-Switch #6 in the DOWN position to enable Slave Clocking. Place DIP-Switch #6 in the UP position to disable Slave Clocking.

Slave Clocking Enabled	=	Switch #6 DOWN
Slave Clocking Disabled	=	Switch #6 UP
Factory Default Setting	=	UP

Switch #7

Request To Send Forced - "RTS"

(Asynchronous/Synchronous Mode/Leased Line/Dial-Up)

If your computer or terminal uses RTS-CTS protocol (typically used in some synchronous applications, but also if using hardware pacing for V.42 error correction or speed conversion), you may want to set RTS to function independently of CTS (DIP-Switch #7 UP). For most applications, especially asynchronous, this switch should be set so that RTS is forced On (DIP-Switch #7 DOWN)

RTS functions Normally RTS forced On Factory Default Setting

=Switch #7 UP

=Switch #7 DOWN

=DOWN

Switch #8

Enable/Disable Command Mode -- "Com"

(Asynchronous/Synchronous Mode/Leased/Dial-Up)

In some applications you may want to disable the modem's Command mode so that the modem does not recognize or react to AT or V.25bis commands. This may be true in strictly auto-answer applications where no call origination is required. Place DIP-Switch #8 in the DOWN position to enable Command mode. Place DIP-Switch #8 in the UP position to disable Command mode. The factory default setting is Command mode enabled.

Disable Command Mode	=	Switch #8 UP
Enable Command Mode	=	Switch #8 DOWN
Factory Default Setting	=	DOWN

Switch #9

Digital Loopback Test

(Asynchronous/Synchronous Mode/Leased Line/Dial-Up)

When in Synchronous mode, this switch controls both Local Digital Loop and Remote Digital Loop tests while on-line. When the Voice/Data switch is toggled to the Answer mode position (UP) and DIP-Switch #9 is in the UP position, the modem performs the Local Digital Loopback test. When DIP- Switch #9 is DOWN and the Voice/Data switch is toggled to Answer mode position (UP), the modem performs the Remote Digital Loopback test.

Local Digital Loopback Test	=	Switch #9 UP
Remote Digital Loopback Test	=	Switch #9 DOWN
Factory Default Setting	=	DOWN
