Question: Can the receiver be used with ST-C6HD-HDBT-LC?
Answer: Thank you for your inquiry,

The NTI ST-C6HD-394-LC receiver cannot be used with the ST-C6HD-HDBT-LC, but the ST-C6HD-394-LC would ship with both the transmitter and receiver, and would be a good replacement for the discontinued ST-C6HD-HDBT-LC.

We do also have a couple of sets of the discontinued ST-C6HD-HDBT-LC still in stock if you need a replacement for the ST-C6HD-HDBT-LC receiver. Please feel free to reach out to your KVM Switches Online sales representative directly for a pricing quote. Note, because the ST-C6HD-HDBT-LC is End-Of-Life, it would be a non-cancelable non-returnable order, and we are unable to provide discounts.

Please let us know if there is anything else we can help you with!
