ersion: TEX0 V500R002C00SPCb00, VPT300 V500R003C10SPC100 (With 2 VPC600: VPC620 V500R002C00SPC300)
Customer deployed VPT300 and connect to TEX0, but the Video parameters do not allow adjustments specific to the unit. The camera is recognized VPT300 as VPC620 with no access to the parameters.
1. Check the cable, make sure the cable is correctly connecting with VPT300 instead of one of two VPC620
2. Check VPT300 release note, we found the matched version should be V600R006C00.
TEX0 V5R2 doesn't support control VPT300, in this old version, can only choose VPC300 instead to view the image instead of control.
Only version after V600R006C00 support control the VPT300.
Upgrade TEX0 to version V600R006C00 or later version
