36. IP Firmware
If new K-1900-8-IP firmware is available, after opening the programming software a pop window will come up asking
you if you would like to update firmware. An alternative method of updating can be done by clicking the IP firmware
"Update IP" button. You can then browse to the folder that contains the PIP file for updating the unit's IP firmware. This
method is typically only used when Viking Technical Support has sent you updated IP firmware.
37. Unit Firmware
If new K-1900-8-IP firmware is available, after opening the programming software a pop window will come up asking
you if you would like to update firmware. An alternative method of updating can be done by clicking the Unit firmware
"Update Unit" button. You can then browse to the folder that contains the HEX file for updating the unit's firmware. This
method is typically only used when Viking Technical Support has sent you updated firmware.
Note: Export your phone settings before updating firmware.
38. Import/Export
The Import/Export feature is useful for backing up all the K-1900-8-IP Series phone's programming or for importing
programming when installing multiple units with a majority of the same programming.
39. Clear Phone Settings
Clicking on the "Clear Phone Settings" button in programming will reset all of the Programming Features back to their
factory default settings. Note: This command will not change or reset your IP settings.
40. Clear IP Settings
Clicking on the "Clear IP Settings" will reset all of the IP settings back to their factory default settings. This also clears
paging Group settings and Addresses. Note: This will not effect any speaker or paging settings.
41. Diagnostics
The Diagnostics section in the Viking IP Programming can be used to test the functionality of the two relays, read
current relay status, or to display information on the last card or fob detected by the card reader.
42. REX Input
The K-1900-8-IP has one Request for Exit (REX) trigger input. The REX switch must have a momentary, normally
open contact. When the K-1900-8-IP Series phone detects a contact closure on the REX trigger input it performs one
of the following actions, based on the Relay Mode settings for each relay (see section 17):
NOTE: For security reasons the REX input is only enabled when the relay is set to "Internal".
Relay 1 "Door Strike", relay 2 other: Relay 1 will be activated for the programmed Relay 1 Activation Time.
Relay 1 other, relay 2 "Door Strike": Relay 2 will be activated for the programmed Relay 2 Activation Time.
Relay 1 "Door Strike", relay 2 "Door Strike": If the Relay Activation Delay is disabled, Relay 2 will be activated for
the programmed Relay 2 Activation Time. If Relay Activation Delay is not disabled, Relay 2 will be activated for the
programmed Relay 2 Activation Time, then after the Relay Activation Delay time has passed, Relay 1 will be activated
for the programmed Relay 1 Activation Time. This is useful in two door vestibule applications where Relay 1 is used to
unlock the outside door, and Relay 2 is used to unlock the inside door.
