26 HDMI5 Component Video Switch
‘clt’ is a bitmapped parameter, mapped as follows:
Decimal Value +128 +64 +32 +16 +8 +4 +2 +1 Bit Position 76543210 Name 00000DJTHENVEN Factory Settings: 00000000
VEN - 0=Vertical sync pass through. 1=Vertical sync always low. HEN - 0=Horizontal sync pass through. 1=Horizontal sync always low. DJT - 0=Horizontal dejitter off. 1=Horizontal dejitter on. 0 - Reserved, always set to 0.
Switching Delays Allows setting of the Video and Audio switching delays.
SD video_delay,audio_delay,$ Set new settings SD ? Query for current settings SD Query for current settings Response String: =SD video_delay,audio_delay Where: video_delay = Video switching delay in 15.626 millisecond increments. audio_delay = Audio switching delay in 15.626 millisecond increments. $ = If present, settings are backed up in EEPROM.
Relay Control Controls the state of the relays.
RL rly_n,state,$ Set the state of relay ‘rln’ RL rly_n,? Read the state of relay ‘rln’ RL ? Read the state of both relays Response String: =RL rly_n,state

K.I.S.S.™ (Continued)
space before the comma is optional. Most commands can be queried for their current settings by substituting the ‘?’ for the parameter list, or by not supplying any parameters at all. For instance to request the current LED Intensity settings:
LI ?<CR>
or
LI<CR>
This would cause the device to issue a LED Intensity Response, (the Response String format is described in the section entitled: “The Response String”). The whitespace before the ‘?’ is optional. Most Zektor products use the K.I.S.S. command structure, the examples given here to describe syntax, may differ slightly from the commands used by your device. Please see the “Command Reference” section for the specifi c commands used by your device. Using Bitmapped Parameters Some commands accept “Bitmapped” parameters. These are decimal values that represent a series of fl ags, or bits, that control, enable and/or disable different device operations. Binary arithmetic is used to represent bitmapped parameters, it is assumed the reader has some familiarity with binary arithmetic. An example of a command that uses a bitmapped parameter is the CVS4’s “XS settings<CR>” command, which is defi ned like this:
XS settings<CR> Where ‘settings’ is a bitmapped parameter:
Decimal Value +128 +64 +32 +16 +8 +4 +2 +1 Bit Position 76543210 Name 0 CRC CSE IRJ IRS IRE FP AS Factory Settings: 00011110
AS - 0=Master / Slave mode. 1=Asynchronous Mode. KB - 0=Disable Front Panel. 1=Front Panel Enabled IRE - 0=Disable IR. 1=Enable IR. IRS - 0=Turn off IR Sensor. 1=Turn on IR Sensor. IRJ - 0=Turn off IR Jack. 1=Turn on IR Jack. CSE - 0=Disable CS and CRC-8 1=Append either Checksums or CRC-8 to responses. CRC - 0=Append Checksums or, 1=Append CRC-8’s to reponses. 0 - Reserved, always set to 0.
This indicates the parameter ‘settings’ is bitmapped parameter, followed by a description of what each bit represents. The ‘Decimal Value’ in the table’s header, refers to the values added together to create the deci-
