Q & A

Q: What’s the difference between different functional versions?

A: The PQ1 is available in N1 and N2 version, N1PQ1 is discontinued. Differences are as below:

E13 functionNot supportedSupported
CRC functionNot supportedSupported

Q: What's the difference between D75S and D12S?

A: D75S and D12S are E1 interface boards for PQ1, D75S is 75ohm, D12S is 120ohm.

Q: Can I use 120ohm cable connect on D75S?

A: No, you can’t, if you use 120ohm cable, please choose D12S interface board. To avoid incompatibility, please tell sales team your resistance.

Q: Does D75S /D12S come together with PQ1 board?

A: Yes, D75S / D12S price is inclusive in PQ1 board.

Q: Does E1 cable come together with PQ1 board?

A: No, you need purchase separately. To avoid incompatibility, please tell us your resistance

Q: How many E1 cable do I need?

A: PQ1 E1 cable is 8*E1 per PCS, you need 8PCS per each PQ1 board; length is 3m, 5m, 10m as per your needs. But in normally condition, 5 meter per each is enough.

Q: How could I do, if I have PQ1+D75S, but my DDF is 120ohm?

A: You may choose a 75ohm/120ohm converter, it looks like a DDF panel, can fix on your DDF rack to convert 75ohm to 120ohm.

Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before your purchase.

Q: The board is new or refurbished?

A: Yes, it is original new, not been used.
