DIP switch 2 settings
DIP switch (SW2) position 1 selects the daisy chain's baud, 9600 or 2400 bps.
SW2 position 2 selects the daisy chain's parity, number of data bits, and number
of stop bits—the daisy chain's terminal settings. SW2 position 3 selects the
HLC's firmware execution mode: allow FLASH or force E-PROM. SW2
position 4 designates the PBX as either a Meridian 1 or an SL-100 switch. SW2
positions 5–8 of are not used for release 4 of the HLC.
Note: For firmware upgrades, SW2 position 2 must be OFF, providing for
terminal settings of N81 (no parity, 8 data bits, and 1 stop bit). See "UPLOAD
(U) command" on page 159 for further requirements to execute a firmware
upgrade via this MMI command.
The following table lists the function of each position on DIP Switch 2 (SW2).
