Hotels / motels using PMS (Property Management System) to manage operating data and billing guests (on transparencies / room, convenience and other costs). Interface interfaces to PMS billing systems, such as valuable call records, are sent directly to guest diaries.
Different PMS uses different interfaces. The interfaces differ in how the call record data is packaged. Some accounting accounting systems come pre-programmed from production, while others have to be configured on site. Most call counting systems use one of three different types of interfaces: MR (rarely used) and the two most popular HB and HX covered here.
PMS-HB. These systems require a line-up (LF) before the call record, before the call record and three control characters (line load / LF, carriage return / CR and form print / FF). The PMS-HB systems must recognize that one of the three is the "end". During testing, FF can grab installers / technicians – FF form and send paper or monitor "top of page" – look back at a page!
PMS-HB supports bi-directional ("manual shake") and 1-way communication between PMS and call counting systems ("CAS"). In bidirectional mode, PMS and CAS can acknowledge or acknowledge each call record. CASs are "told" to send or whether the call record is OK or if not, hold or the call record must be resubmitted. The handshake control characters are ACK (ASCII hex 06) and NAK (ASCII hex 21) – (or lowercase "y" and "n"). Typically, PMS-HB systems do not require manual shake, so if not, CAS systems send call records and the reception is OK.
PMS-HX. HX call counting systems are given permission to send call records in order for the PMS to be ready to send an ENQ (ASCII hex 05) query for the first time. When done, the PMS sends an ACK (ASCII hex 06) message so that CAS sends an STX (ASCII hex 02) text input before the call record, followed by an ETX (ASCII hex 03) end-of-text and block check character. The block check character allows PMS to perform parity check on CR's received accuracy. If the PMS "likes" the call record, it sends an ACK to the CAS.
Useful for installers / technicians using a laptop or monitor on the PMS-CAS connection (Laptops are even better with communication software than HyperTerminal – available on most Windows systems). Some communication packets display control characters as icons; eg. the ENQ club, ACK ace, etc. Software often allows you to send control characters by pressing ctrl () and another key. Example: To send ACK, press ctrl with F.
If communication parameters and handshake characters are matched between CAS and PMS, you are running. Call Handling Manuals generally include a detailed description of PMS interface protocols. Manuals or special technical information can often be downloaded from CAS vendors & # 39; site.
